A report from the University of Novi Sad discusses research on gold nanoparticles and their potential use in detecting Trichoderma species in mushroom cultivation. Trichoderma species can negatively impact mushroom production and cause economic losses. The researchers developed a loop-mediated isothermal amplification (LAMP) assay coupled with gold nanoparticles for rapid colorimetric detection of Trichoderma. The assay is based on the aggregation of gold nanoparticles, which can be observed with the naked eye, providing a simple initial screening for the presence of Trichoderma in mushroom cultivation substrates.

Effect of bio-controllers isolated from onion production fields on white rot disease (Sclerotium cepivorum). To evaluate the effect of Trichoderma sp., Clonostachys spp., and Beauveria bassiana on white rot disease (Sclerotium cepivorum) on onion, a greenhouse experiment was conducted. Isolates used were recovered from sclerotia collected from onion production fields, in the highlands of Cartago, Costa Rica. Onion seedlings were cultivated in 3.5 kg pots with inoculated soil (0.06 sclerotia.g-1 of soil). Individual or mixed bio-controllers were applied at 3 different times: first at potting time (230 g.pot-1), second and third 4 and 8 weeks afterwards (500 ml of substrate.pot-1, with 5x106 cfu.ml-1). Disease incidence was evaluated at 18 weeks. Results showed a p=0.0117 statistical difference between the control treatment (without bio-controllers) and the other treatments. Disease incidence showed the following pattern: control 46%; Beauveria bassiana 17%; Clonostachys spp. 8.3 and 7.1%, respectively; Trichoderma spp. O%. The ANOVA showed no differences (p=0.5883) among leaf-size values. These results indicate that all bio-controllers evaluated exert some level of disease control, particularly Trichoderma spp. [ABSTRACT FROM AUTHOR]

The discovery of disease suppression in certain bark composts increased the interest in using compost as growing substrate to control root rot diseases caused by Phytophthora cinnamomi. Disease suppression mechanisms include antibiosis, competition, hyperparasitism, and induced systemic resistance. Although abiotic factors may influence disease suppression, the latter is often based on microbial interactions--the two common mechanisms being general for pythium (Pythium spp.) and phytophthora root rot (Phytophthora spp.) and specific for rhizoctonia (Rhizoctonia solani). The discovery of disease suppression agents in compost led to the development of biocontrol agent-fortified compost during the last decade of the 20th century. The suggested recommendations for future research and extension outreach may include 1) development of methods to manage bacterial and viral diseases through the use of compost; 2) exploration of the potential effects of fortified compost on insect pests suppression; 3) improvement of inoculation methods of composts with biocontrol agents to produce consistent levels of disease suppression at the commercial scale; 4) development of effective fortified compost teas for suppressing foliar diseases; 5) education of compost producers on methods of production of fortified compost that suppress specific diseases; and 6) education of end-users on uses of fortified compost and its by-products.

The solid substrate cultivation (SSC) process is often limited by rapid increases in temperature as a result of metabolic activity and poor heat transfer properties of the solid substrate. High temperatures can adversely affect microbial growth and product formation. Reduction of substrate temperatures is important for improved productivity, yet effective and efficient control of heat transfer in a deep-bed SSC reactor has proven difficult. An internal cooling water coil was incorporated into a deep-bed reactor system and evaluated for its ability to reduce substrate temperature. Three operating treatments were investigated: cooling water circulation whenever the center bed temperature was above 30 °C, timed cooling water operation on 10 min on/off intervals from the start of cultivation, and timed operation on 10 min on/off intervals after the expected start of microbial exponential growth. Enzyme yield, peak temperature, and net rate of metabolic heat accumulation within the substrate bed were measured during the cultivation of Trichoderma longibrachiatum on wheat bran for xylanase production. The cooling water reduced the temperatures observed in the substrate bed by 5 °C on average and was effective in decreasing the rate of heat accumulation in the bed. Within a 10 min time interval, the internal heat exchanger demonstrated a net decrease in heat accumulation at an average rate of approximately 0.5 °C/min. Despite the decrease in temperatures observed with the control strategies, the xylanase yields were not statistically different from the cultivations with no temperature control.
