Peanut southern blight is a fungal disease which is caused by the pathgen Sclerotium rolfsii Sacc., and seriously restricts the quality and yield of peanut. In this study, 116 strains of actinomycetes were isolated and purified from rhizosphere soil of Achyranthes bidentata by dilution coating method, and the strains that can control peanut southern blight were screened and identified. Two strains, Soil-1-5 and Soil-3-28, with good and stable antifungal activity, were screened by the plate confrontation test, and their inhibition rates were 80.43% and 92.34%, respectively. Morphological observation, physiological and biochemical tests, and 16S rRNA gene sequence analysis identified strains Soil-1-5 and Soil-3-28 as Streptomyces scabiei and Streptomyces luteogriseus, respectively. The inhibition of aseptic fermentation filtrate of antagonistic strains on plant pathogens was measured by mycelium growth rate method. The results showed that after 5 times dilution of aseptic fermentation filtrate of strains Soil-1-5 and Soil-3-28, the inhibit rates of S. rolfsii were 73.67% and 57.11%, respectively, and the two strains had different degrees of inhibition effects on the six plant pathogens including Fusarium graminearum. In addition, the two strains of aseptic fermentation filtrate also had good antagonistic effects on the sclerotinia germination and sclerotinia formation. The results of pot experiment showed that the control effects of strain Soil-1-5 and Soil-3-28 on peanut southern blight were 51.92% and 31.74%, respectively, and strain Soil-3-28 could promote the growth of peanut. In conclusion, strains Soil-1-5 and Soil-3-28 had better control efficacy on peanut southern blight, and had potential application value. [ABSTRACT FROM AUTHOR]

The corrosion failure behavior of a natural gas gathering and transportation pipeline was examined. The corrosion morphology characteristics and product composition of the pipeline were also determined, as were the corrosion failure characteristics, corrosion types, and failure mechanism. The failure analysis of pipeline was made by taking an experimental research as the primary means. The corroded parts and macroscopic features of the inner wall of the pipeline ware analyzed through macroscopic surface measurement. The pipeline materials was tested,such as mechanical properties, microhardness, chemical composition and metallographic analysis. Scanning electron microscopy ( SME) was used to analyze the morphology of the corrosion products. Energy dispersive spectroscopy ( EDS) and X-ray diffraction ( XRD) were used to analyze the phase of the corrosion products. The results show that the matrix's chemical composition and mechanical properties meet the national standard and the typical metallographic structure. CO2 corrosion occurred in pipeline steel L245 in a high salinity water environment, forming loose, porous, cracked corrosion products in clusters. The main components of the corrosion product are FeCO3 and Fe2O4 . Due to the low bonding strength between the corrosion product film and the metal matrix, it is easy to strip under the action of the erosion of the fluid medium, accelerating the dissolution of metal and the diffusion of corrosive substances, and forming electrochemical corrosion with autocatalytic effect.

Silk has been used in China for thousands of years and is the only natural filament fiber in nature that can be mass-produced, which is of great significance in the textile industry. In recent years, protein films, a derivative material of silk, have attracted much attention and are widely used in the fields of antimicrobial dressings, bone repair scaffolds, slow-release carriers and biosensors, and have become a high-tech material with a promising future. Despite the superior mechanical properties of native silk, the strength and toughness of regenerated silk-protein membranes are unsatisfactory, which greatly hinders their wide application. To enhance the mechanical strength of regenerated sericin materials, some scholars have enhanced the mechanical strength of regenerated sericin materials by mixing natural proteins, such as wool keratin and spider silk protein, and also improved the softness and ductility of regenerated sericin materials by adding non-protein components, such as glycerol and polyvinyl alcohol, of which glycerol can also promote the interactions between the molecules of sericin and the water molecules to improve the hydrophilicity of sericin. Both protein and non-protein addition methods are often accompanied by problems such as complex dissolution, cumbersome process, waste of resources and environmental pollution. Wool keratin-associated proteins (KAPs) are fibrous proteins rich in cysteine, capable of forming disulphide bonds upon oxidation. These bonds, along with hydrophobic interactions and van der Waals forces, contribute to the high mechanical strength and structural stability of keratin. In this study, KAP-incorporated silk was generated through transgenic methods and used as the material. Silk protein membranes were then obtained by gradually removing water from the silk protein solution and shaping it accordingly. Furthermore, 1% glycerol was added to the silk solution to modify the protein membrane. We tested the secondary structure, physicochemical properties, and mechanical properties of ordinary sericin protein membranes, KAP-incorporated sericin protein membranes, and glycerol-plasticized protein membranes, and then analyzed the improvement of sericin protein membranes by the incorporation of KAP. In this study, we used the KAP-incorporated silk obtained by transgenic transfer of the wool keratin gene into the silkworm, Bombyx mori, to produce performance-enhanced hybrid silk-protein membranes. Compared with the tedious process of dissolving silk and wool separately and then mixing them in the traditional method of making hybrid protein membranes, this method has the advantages of relative simplicity and higher efficiency, and provides a new way and idea for the research and utilisation of natural proteins such as silk and wool. The KAP-incorporated sericin protein membranes produced were tested, and it was found that the incorporation of KAP protein could increase the secondary structure of the stability of silk fibroin membranes and improve the mechanical properties of the membranes, and the adding of glycerol could also significantly improve the tensile properties and hydrophilicity of the KAP sericin membranes. The production of silk/wool keratin mixed protein films through transgenic methods has the characteristics of simplicity, zero pollution, and excellent performance, which can provide new ideas for the research and application of natural silk materials.
