Summary: This study screened three strains with high inhibition rate against Sclerotinia sclerotiorum from 69 samples of Doenjang collected in different regions to develop a bio-inhibitory agent. The fermentation conditions of one strain were optimized, showing all three fermentation filtrates inhibited S. sclerotiorum. The living bacteriostatic test demonstrated the significant inhibitory effect of one strain on S. sclerotiorum, especially at higher bacteria concentrations.

Summary: This study investigated the potential of 13 Bacillus spp. strains isolated from paddy soil to reduce ammonia emissions during pig manure storage. Five strains were found to significantly reduce ammonia emissions by 23.58% to 26.82% over 60 days. The strains also showed tolerance to different pH levels, salinity, and ammonium-nitrogen concentrations.

Summary: Bacterial metabolites, including erucamide, behenic acid, palmitic acid, phenylacetic acid, and beta-sitosterol, were isolated and purified from Bacillus megaterium L2 for the first time. Among these compounds, beta-sitosterol demonstrated significant antimicrobial activity against RS-2, while behenic acid and phenylacetic acid showed potential for prevention and control of phytopathogenic bacteria.

Summary: This study isolated a broad-spectrum antibacterial Bacillus strain from the deep sea, and identified fengycin and surfactin as the active agents with strong inhibition against P. aeruginosa PAO1 and MRSA. Further investigation revealed that the inhibition mechanisms are related to ROS accumulation and decreased CAT and SOD activity.

Summary: In recent years, nitrogen pollutants have become a major cause of water pollution and eutrophication, highlighting the importance of research on nitrogen removal in wastewater. This study isolated and identified a bacterium, Bacillus tequilensis (A2), with remarkable capability for ammonia nitrogen degradation. The study also successfully expressed a new nitrite reductase gene in E. coli BL21 (DE3) and characterized its properties.

Summary: Apple anthracnose is a severe global fungal disease, and this study isolated, purified, identified, and applied an antifungal protein from Bacillus subtilis SL-44 for controlling Colletotrichum gloeosporioides. The antifungal protein showed excellent broad-spectrum activity against plant pathogenic fungi. The optimal fermentation conditions were determined, and the antifungal protein's production was improved by 45.83%. The protein was identified as a novel protein with a molecular weight of 42 kDa and was found to disrupt the cell wall structure of C. gloeosporioides, leading to its antifungal action. In apple infection protection tests, the antifungal protein significantly reduced lesion size by more than 70%. This study highlights the remarkable potential of antifungal protein in developing fungicides for the biological control of apple anthracnose.

Summary: Penicillium expansum is the main cause of apple rot, causing significant economic losses during apple storage. A bacterium named YL-RY0310 was isolated, which effectively inhibited the growth of P. expansum and production of PAT in apples. Morphological and genetic analysis revealed that YL-RY0310 is 96% homologous to Bacillus mojavensis.
