Soft rot chryseobacterium indologenes ,Antibacterial activity ,Ferula communis - Abstract
In this study, it was aimed to determine essential oil and extracts, which are known as Ferula communis and obtained from naturally grown giant fennel plants in A?ri province, antioxidant effects and antimicrobial effects against Chryseobacterium indologenes which cause soft rot in certain vegetables and fruits in vitro. Also was determined the chemical composition of essential oils used in this study. For this purpose, 8 C. indologenes isolates, which were determined to be soft decay agents in cucumber, tomato, pepper and squash, were used in previous studies. Laboratory trials were established in triplicate and penicillin and kanamycin antibiotics, which are commercially available, were used as positive controls in the experiments. According to the obtained results; It has been observed that essential oils gained from F. communis plant have bactericidal activity against bacterial pathogens in the ratio of 12-21 mm. However, none of the extracts obtained from the F. communis plant used in the study were found to have antibacterial activity against C. indolenes species. Antibiotics used as positive controls have also been observed to have no effect against pathogens as in the extracts. As a result, it has been determined that the essential oil used in the study has a lethal effect against 8 different C. indologenes which have soft caries pathogens, but the extracts and antibiotics used have no antimicrobial effect. In addition, the chemical composition of essential oil determined to be effective in the study has been determined. For this reason, it is considered that the essential oil obtained from F. communis plant can be used successfully in the control against C. indologenes pathogens. This result shows how much the F. communis essential oil has a great importance in control against these pathogens very resistant to chemical drugs. In this study, antioxidant capacity of F. communis methanol, acetone, chloroform, hexane extract and essential oil was determined by DPPH and ABTS method, phenolic substance contents and folin was determined by cycaltio method. Water extract had highest ABTS free radical scavenging activity with 88.07% (0.05 mg/ml), (DPPH) capacity with 52,04% (50 ?g/ml) and highest amound of phenolic compound with 13,25 (mg GAE/gr). © by PSP.

The present study aims to identify Pectobacterium carotovorum, known as one of the most common soft rot causative agents using classical and molecular methods. Four different P. c. subsp. carotovorum strains from various hosts were obtained, two of which are causative agents of soft rot disease in potato and the other two in onion or pepper. These strains were confirmed as P. c. subsp. carotovorum by microbial identification system (MIS). In addition, BIOLOG system was used to identify these strains and the results were found to be inconsistent with those of microbial identification system. Test results of hypersensitive reaction (HR), pathogenity a nd pectolytic activity proved that all strains were pathogens. A number of biochemical and molecular analyses (16S rDNA and specific PCR) were conducted for identification and characterization. The strains were identified in genus level by means of 16S rDNA PCR method. Identified as P. c. subsp. carotovorum according to MIS results, these four strains were analysed in specific PCR tests and found to give 434 bp-long band with Y1-Y2 primers. This is the first study to reveal that these four strains are causative agents of soft rot disease in potato, onion and pepper in East Anatolia and also in Turkey. © 2017, Pakistan Agricultural Scientists Forum.

The aim of this study was to test for antibacterial efficiacy and potential use as seed disinfectants of extracts and essential oils of Satureja hortensis, Satureja spicigera, Origanum onites and Origanum rotundifolium against Xanthomonas axonopodis pv. vesicatoria causes of bacterial leaf spot of pepper and tomato. According to the in-vitro test results, the essential oils showed a strong antibacterial activity based on the zone of inhibition against pathogen on Petri plates. The inhibasyon zones and MIC values of the essential oils ranged from 29-42 mm and 15.62-125 mu l/mL, respectively. However, the extracts showed weak or no antibacterial activity. According to the results on petri plate assays of O. rotindufolium and S. spicigera essential oils, some of the concentrations (31.25 and 62.50 mu L/mL) had toxic effect on the pepper seed germination, but the concentration of the oil with 15.62 mu L/mL had not toxic as compared to only the pathogen application. This application caused a decrease on the number of the infected seedlings with X. axanopodis pv. vesicatoria. Furthermore, this decrease was statistically significant compared to both streptomycin sulfate and only pathogen applications. On the other hand O. onites hexane extract had a toxic effect on the pepper seed germination, but all concentration of the acetone extract and chloroform extracts (except 20 mg/mL) had no toxicity. According to the results on pot assays, essential oils used in the best germination and disease control was observed at lower doses. In the application of the O. onites extracts onites the best germination and best disease control have changed according to the dose used. Our results showed that some of the concentrations of the essential oils and/or extracts from S. hortensis, S. spicigera, O. onites and O. rotindufolium can be used as a seed disinfectant and as potential control agents for management of the bacterial disease., Scientific and Technical Research Council of Turkey (TUBITAK) [TOVAG-107 O 525]; Ataturk University Research Foundation [BAP: 2009/53], This study was supported by The Scientific and Technical Research Council of Turkey (TUBITAK) under the project TOVAG-107 O 525 and by Ataturk University Research Foundation (BAP: 2009/53).

In this study, 5 bacterial strains (Bacillus cereus, Bacillus atrophaeus, Bacillus globisporus, Brevibacillus brevis, and Alcaligenes denitrificans subsp. xylosoxydans), isolated from different insect species in the Eastern Anatolia region of Turkey, were identified on the basis of fatty acid methyl ester analysis and carbon source utilization profiles by using Microbial Identification System (MIS) and/or MicroPlate Systems (BIOLOG). Their insecticidal effects were tested on adult Caliroa cerasi on Petri dishes, in vitro. Seven days after application, all of the tested strains showed more or less insecticidal activity against this pest. The highest activities were obtained from Brevibacillus brevis strain FD-1 and Bacillus cereus strain FD-63 causing 86.7 and 100% mortality, respectively. These values were not statistically different from that of the positive control (Kingbo). The mortality rates of the other bacterial applications were lower than that of the positive control, but not that of the negative control. In conclusion, Bacillus cereus strain FD-63 and Brevibacillus brevis strain FD-1 are good candidates for use as biological control agents against this economically important pest. © by PSP.

POTATO scab , *BIOLOGICAL pest control agents , *STREPTOMYCES , *POTATO diseases & pests , *POTATO yields - Abstract
Common scab caused by Streptomyces species is an important disease worldwide. Huge economic losses are faced because of the disease every year and control options are scant. This study was conducted to develop effective biocontrol agents, which have capability of enhancing potato yield. A total of 1048 bacterial isolates from former studies were tested against S. scabiei in-vitro and 22 out of these strains were found to be effective. Most effective four strains (KBA- 10, K-19B, TV-91C and RK-92) were chosen for field trials. All four strains can fix nitrogen and dissolve phosphate. According to the result, KBA-10, TV-91C, RK-92 and K-19B have biocontrol efficacy of 60.35%, 37.2%, 33.5% and 18.7%, respectively. They increased potato yield 40.0%, 41.1%, 25.52% and 20.42 %, respectively, compared to control. Increases provided by KBA-10, K-19B and TV-91C were found to be statistically significant. Biocontrol efficacies of K- 19B, TV-91C and RK-92 were of lesser degree, compared to KBA-10. Additionally, KBA-10 generated an extensive rise (71.7%) in tuber number. KBA-10 can be a good biocontrol agent for reducing potato scab disease and enhancing crop yield. Moreover, KBA-10 can be used in tuber seed production. [ABSTRACT FROM AUTHOR]

fungi ,food and beverages - Abstract
The essential oil isolated from the aerial parts of wild Turkish Satureja hortensis L. (summer savory) was analyzed by GC-MS, and carvacrol (54.7 %), gamma-terpinene (20.9 %), p-cymene (12.3 %), alpha-terpinene (2.0 %), and thymol (2.0 %) were found to be major components of the oil. Post-harvest decay of fruits caused by some fungi is still a most important problem and causes major crop losses during storage and shipment. High relative humidity during storage and marketing conditions accelerate development of fungal disease and decay of the grapes. The six different concentrations of the oil (0.01, 0.02, 0.04, 0.11, 0.22 and 0.45 mu L/cm(3)) were tested for their effectiveness in reducing decay of strawberry and grape fruits at three storage temperature (5, 10 and 20 degrees C). The oil tested reduced decay of strawberry and grape fruits compared to controls, in particularly at low temperatures (5 and 10 degrees C). Decay reducing effect of the oil on strawberry and grape fruits increased with increase in doses of the oil. However, microbial development in the fruits increased with increase in temperature. Nevertheless, the present results showed that S. hortensis essential oil has a significant reducing effect on the decay of strawberry and grape fruits during storage at low temperatures. Therefore, the essential oil of summer savory may be a potential source of alternative fungicides to protect strawberry and grape fruits as well as other stored products from pathogens and saprophytes.

16S rDNA sequence analysis ,pine sawfly ,Biocontrol ,Bacillus ,Biopesticide - Abstract
Diprion pini is one of the most important pests in forest trees around the world. Also the pest was determined in pine forests around the Turkey, causing outbreaks in some regions. Therefore, this study aimed to develop bacterial biopesticides, which can be used to control Diprion pini remarkably and at the same time which do not threaten the environment and human health. Bacterial strains which were effective against different pests in some studies were used. Their insecticidal effects were tested on larvae of Diprion pini in vitro on petri dishes. Seven days after applications, some of the tested strains showed more or less insecticidal activity against this pest. The highest activity was obtained for strains FD-17 and FD-1causing 66.7-80% mortality, respectively. The activities of the other bacterial applications were not statistically different from that of the negative control. In conclusion, strains FD-17 and FD-1 are good candidates for use as biological control agents against this economically important pest. These effective strains were characterized to the species level by 16S rDNA sequence analysis. According to the results, both strains have been identified as Bacillus atrophaeus.

Nine bacterial strains isolated from different insect hosts were identified by using Sherlock Microbial Identification (MIS) system. Cell suspensions of the bacteria were tested for their larvicidal activity against the larvae of Culex pipiens L. (Diptera: Culicidae) under laboratory conditions. Fatty acid methyl esters (FAMEs) profiles and profiles of nutrient substrate utilization by the most effective strains were determined. Nitrogen fixation, antibiotic resistance and salt tolerance of these strains were also investigated. Separately, they were tested for toxicity in non-target aquatic organisms, including common water fleas, Daphnia magna and Nile tilapia (Oreochromis niloticus L.). Tested strains were identified as Bacillus thuringiensis (6 strains), Bacillus sphaericus (2 strains) and Brevibacillus brevis (1 strain). The identification was also confirmed by BIOLOG system. A mortality of 100% of Culex larvae was observed after 24 and/or 48 hrs, following treatment with the cell suspension of Brevibacillus brevis FD1, B. sphaericus FD48 and B. sphaericus FD49 strains. Major fatty acids of B. sphaericus FD48 and FD49 strains were C15:0 iso, C15:0 anteiso and C16:1 w7c alcohol. Major fatty acids of the B. brevis FD1 strain was C15:0 anteiso, C15:0 iso and C17:0 anteiso. B. sphaericus FD48 and FD49 strains had similar substrate utilization patterns. Methyl pyruvate was the only substrate utilized by FD1, FD48 and FD49 strains. The strains grew in N-free Döbereiner culture medium, toleranced to salt and were resistant to amikacin, kanamycin, penicillin, tobramycin, ofloxacin and sulphamethoxazole. B. brevis FD1, B. sphaericus FD48 and FD49 whole culture gave an LC50 of approximately 103 cells/ mL for susceptible C. pipiens larvae, whereas a concentrated 109 cells/ml culture had not affected any in common water fleas and Nile tilapia survival. No mortality was observed throughout the 3-week experiment. In conclusion, B. brevis FD1, B. sphaericus FD48 and FD49 strains can be developed and recommended for biocontrol of mosquitoes. © 2013, Egyptian Society for Biological Control of Pests.

Artemisia spp ,chemical composition ,Antibacterial activity ,essential oil - Abstract
This study was carried out to determine antibacterial activity of essential oils, extracts and major components of three Artemisia species (A. absinthium, A. santonicum and A. spicigera) against to some seed borne bacterial plant pathogens. According to our results, essential oils and some major components of Artemisia species have antibacterial activities at varying rates while extracts have shown no activity against any of the pathogens. Disc-diffusion method was used to test antimicrobial activity of the essential oils and extracts According to the results obtained, essential oil of A. santonicurn has antibacterial effect against to 24 of 25 bacterial strains, essential oil of A. absinthium has antibacterial effect against 15 of 25 bacterial strains and essential oil of A. spicigera has antibacterial effect against only three of 25 bacterial strains. Additionally, constituents of the essential oils were analyzed by GC MS method. Camphor, caryophyllene oxide, linalool, 1,8-cineole, teminen-4-ol, borneol and alpha-terpineol were determined as predominant components. Minimum-maximum inhibition zones and MIC values of linalool were 8 mm (C. violaceum RK-231) - 45 mm (X campestris pv. vitians RK-Xcvi), 50-110 mg/ml; terpinen-4-ol 8 mm (B pumilus RK-106) - 43 mm (X campestris pv. vitians RK-Xcvi) and MIC values 60-110 mg/ml; alpha-terpineol 8 mm (P.cichorii RK-166 and X axamopodis pv. vesicatoria RK399) 10 mm (P. huttiensis RK-260 and P. syringae pv. syringae RK-204) and 60-70 mg/ml, respectively. But caryophyllene oxide, bomeol, camphor and 1,8-cineole didn't show activity against any of the pathogens. In sum, our findings suggest that essential oils may be valuable as potential antibacterial agents against some plant pathogens., Scientific and Technological Research Council of Turkey (TUBITAK) [TO-VAGT-107 O 525], The research is financed by Scientific and Technological Research Council of Turkey (TUBITAK) (project TO-VAGT-107 O 525).

- Abstract
The chemical compositions of hydrodistilled essential oils and n-hexane extracts from Origanum acutidens, O. rotundifolium and O. vulgare were analyzed by GC and GC-MS. Essential oils and hexane, chloroform, acetone and methanol extracts were tested against 25 plant pathogenic bacterial strains. Essential oils showed a wide spectrum of antibacterial activity, probably due to the phenolic components such as carvacrol and thymol. It was also shown that carvacrol, thymol and other main components such as terpinen-4-ol and linalool possess antimicrobial activity. Plant extracts, however, did not show any antibacterial activity, with the exception of the acetone and hexane extracts from O. rotundifolium. Our findings suggest that the essential oils may be valuable as potential antibacterial agents against plant pathogens, and show the potential value of Origanum oils as seed disinfectant.

International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 18-21, 2017 -- Antalya, TURKEY, Peroxidases (EC: 1.11.1.7) are haem proteins and contain iron (III) protoporphyrin IX (ferriprotoporphyrin IX) as the prosthetic group [1]. They are found in all cells and play a critical role in many biological processes, such as the host-defense mechanism [2]. Peroxidases (PODs) are widely used in clinical biochemistry, enzyme immunoassays, synthesis of various aromatic chemicals, treatment of waste water containing phenolic compounds [3, 4]. In this study, peroxidase enzyme was purified with Para amino benzohydrazide (PABH)-L-Tyrosine Sepharose 4B affinity chromatography to investigate the inhibitory effect of hydrazide derivatives on Turnip (Brassica rapa L.). IC50 values and Ki constants were calculated for the molecules of 6-Amino nicotinic hydrazide, 6-Amino-5-bromo nicotinic hydrazide, 2-Amino-5-hydroxy benzohydrazide, 4-Amino-3-hydroxy benzohydrazide on purified enzyme and inhibition type of these molecules were determined., Agri Ibrahim Cecen Univ, IC Fdn

International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 18-21, 2017 -- Antalya, TURKEY, Magnesite, the main source for magnesium and magnesium derivatives, are also commonly used in the production of caustic, dead-burned and fused magnesia. World magnesite resources are estimated to be at 12 billion tonnes mostly located in China, Russia, North Korea, Australia and Turkey. Turkey is the second producer of the magnesite. Magnesite deposits in Turkey are sedimentary magnesite which have been formed in specific conditions as high concentrations of MgSO4 and CO2 and presence of certain organic salts or created by hot or cold dissolution connected with carbonate rocks mainly with dolomites. According to the genesis of magnesite deposits, they have some impurities as calcium, quartz, iron, etc. Impurities of magnesite, especially CaCO3, reduce its economic value and industrial usability. In our previous study, we have performed biotechnologically enrichment of magnesite by Lactococcus sp., which gave significantly important results. However, we had no information about carbonate dissolution mechanism of bacteria. Therefore, it is aimed to reveal the metabolites of Lactococcus sp. and mechanism leading to the carbonate dissolution (MgCO3 and CaCO3)., Agri Ibrahim Cecen Univ, IC Fdn

International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 18-21, 2017 -- Antalya, TURKEY, Like most cultivated crops, onions (Allium cepa L.) are plagued by phytopathogenic bacteria. Although bacterial diseases of onion occur sporadically, they can cause loss of yield, in the range of a few percent up to 40%. Center rot of onion caused by Pantoea ananatis is the one of the major bacterial disease. Cultural methods and copper compounds often are recommended for control of bacterial diseases, but these are insufficient and the use of some chemicals has adverse effects. For these reasons, biological control is important manner for control of plant disease. In this study; it was researched that in-vitro inhibition effect of 271bacterial strains on P. ananatis in-vitro. Commercially available streptomycin, kanamycin and tetracycline disks were used as control. In consequence; three isolates show more or less inhibitory effect against P. ananatis., Agri Ibrahim Cecen Univ, IC Fdn

International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 18-21, 2017 -- Antalya, TURKEY, Carbonic anhydrase (CA) is a family of metalloenzymes that requires Zn as a cofactor and catalyze the quick conversion of CO2 to HCO3- and H+. Inhibitors of the carbonic anhydrases (CAs) have medical usage of significant diseases such as glaucoma, epilepsy, gastroduodenal ulcers, acid-base disequilibria and neurological disorders. The most useful radioisotope, Tl-201, decays by electron capture, emitting Hg X-rays (similar to 70-80 keV), and photons of 135 and 167 keV in 10% total abundance. Therefore, it has good imaging characteristics without excessive patient radiation dose. It is the most popular isotope used for thallium 201 nuclear cardiac stress tests. In the present study, In vivo inhibitory effect of Tl-201 (Thallium-201) on human erythrocyte carbonic anhydrase (CA) activity were investigated., Agri Ibrahim Cecen Univ, IC Fdn

The essential oil and methanol extract of Satureja hortensis were tested for antifungal activity against Aspergillus flavus in vitro on Petri plates and liquid culture, and under storage conditions. The oil showed strong antifungal activity based on the inhibition zone and minimal inhibitory concentration values against the pathogen on Petri plates assays. The very low concentrations of them also reduced wet and dry mycelium weight of pathogen fungus in liquid culture. When the oils at 25, 12.5 and 6.25 µl/mL concentrations were applied to lemon fruits before seven days of pathogen inoculation on storage conditions, the decay on fruits caused by the pathogen could be prevent completely. The results in this study showed that the essential oil of S. hortensis had strong antifungal activity against pathogen fungi tested. So, the essential oil of S. hortensis could be used for management of this pathogen as a potential source of sustainable eco-friendly botanical fungicides. © 2008 Elsevier B.V. All rights reserved.

International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 21-23, 2016 -- Antalya, TURKEY, In this study we examined and compared the three different probabilistic distribution methods for determining the best suitable model in probabilistic assessment of earthquake hazards. We analyzed a reliable homogeneous earthquake catalogue between a time period 1900-2015 for magnitude M >= 6.0 and estimated the probabilistic seismic hazard in the North Anatolian Fault zone (39 degrees-41 degrees N 30 degrees-40 degrees E) using three distribution methods namely Weibull distribution, Frechet distribution and three-parameter Weibull distribution. The distribution parameters suitability was evaluated Kolmogorov-Smirnov (K-S) goodness-offit test. We also compared the estimated cumulative probability and the conditional probabilities of occurrence of earthquakes for different elapsed time using these three distribution methods. We used Easyfit and Matlab software to calculate these distribution parameters and plotted the conditional probability curves. We concluded that the Weibull distribution method was the most suitable than other distribution methods in this region.

International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 21-23, 2016 -- Antalya, TURKEY, Herd management requires multidisciplinary practices including animal feeding, gynecology, artificial insemination, immunology, and similar topics. Animal feeding is the most delicate subject as the fodder expense is 70% of the farm cost and as nearly all of the metabolic diseases arising out as health problem are because of misfeeding. However, a business organization's being able to maintain making profit will be possible by taking a healthy calf from breeding herd every year. For this reason, precision registrations of birth and artificial insemination, following-up pregnant state of animals, and making the other animals pregnant as soon as possible should be primary aim. It should not be forgotten that diarrhea and pneumonia in calves are among the most frequently witnessed infection related health problems. Mastitis, metritis and foot diseases take an important place in mature cows. These diseases can be minimized by vaccinations that are done properly and in suitable time, in-service training of staffs, making shelters suitable for animals welfare, and improving the hygienic conditions.

International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 21-23, 2016 -- Antalya, TURKEY, We investigated earthquake hazard parameters for Eastern part of Turkey by determining the a and b parameters in a Gutenberg-Richter magnitude-frequency relationship. For this purpose, study area is divided into seven different source zones based on their tectonic and seismotectonic regimes. The database used in this work was taken from different sources and catalogues such as TURKNET, International Seismological Centre (ISC), Incorporated Research Institutions for Seismology (IRIS) and The Scientific and Technological Research Council of Turkey (TUBITAK) for instrumental period. We calculated the a value, b value, which is the slope of the frequency-magnitude Gutenberg-Richter relationship, from the maximum likelihood method (ML). Also, we estimated the mean return periods, the most probable maximum magnitude in the time period of t-years and the probability for an earthquake occurrence for an earthquake magnitude >= M during a time span of t-years. We used Zmap software to calculate these parameters. The lowest b value was calculated in Region 1 covered Cobandede Fault Zone. We obtain the highest a value in Region 2 covered Kagizman Fault Zone. This conclusion is strongly supported from the probability value, which shows the largest value (87%) for an earthquake with magnitude greater than or equal to 6.0. The mean return period for such a magnitude is the lowest in this region (49-years). The most probable magnitude in the next 100 years was calculated and we determined the highest value around Cobandede Fault Zone. According to these parameters, Region 1 covered the Cobandede Fault Zone and is the most dangerous area around the Eastern part of Turkey.

International Conference on Advances in Natural and Applied Sciences, ICANAS 2016, Oxidative stress can be defined as the instability between antioxidant defense of the body and the production of free radical that causes peroxydation on the lipid layer. Free radicals are reactive oxygen species that are produced in the course of normal metabolisms of aerobe organisms and they may cause disorders in cell structure and organelles by interacting macromolecules, like lipid, protein, nucleic acids. Therefore, they may cause cardiovascular, immune system, liver, kidney illnesses and many other illnesses like cancer, aging, cataract, diabetes. It is known that many drugs used for the purpose of anesthetizing may cause lipid peroxidation in organism. For these reasons, determining the Oxidative stress index of anaesthetic stress chosen in the ones that are exposed to long term anaesthetic agents and anaesthesia appliccations, is so substantial., Agri Ibrahim Cecen University;IC Foundation

International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 21-23, 2016 -- Antalya, TURKEY, The AIP Successive ionic layer adsorption and reaction (SILAR) is an economic and simple method to growth thin films. In this study, SILAR method is used to growth Selenium (Se) and Tellurium (Te) doped zinc oxide (ZnO) thin films with different doping rates. For characterization of the films X-ray diffraction (XRD), absorbance and scanning electron microscopy (SEM) are used. XRD results are showed well-defined strongly (002) oriented crystal structure for all samples. Also, absorbance measurements show, Te and Se concentration are proportional and inversely proportional with band gap energy, respectively. SEM measurements show that the surface morphology and thickness of the material varied with Se and/or Te and varying concentrations.
