Summary: Alkali lignin-degrading Bacillus were isolated from forest soils in China and identified as Bacillus subtilis TR-03 and Bacillus cereus TR-25. The strain TR-03 showed efficient alkali lignin degradation and decolorization capabilities, mainly through the production of lignin peroxidase and laccase. Additionally, physical and chemical changes of lignin were observed via SEM and FTIR analysis to confirm the lignin degradation by Bacillus subtilis TR-03.

Summary: A novel Dehalobacter strain capable of transforming TCM to dichloromethane was obtained, along with its ability to transform other chlorinated compounds. Analysis of 16S rRNA genes confirmed growth of Dehalobacter with TCM and other chlorinated compounds as electron acceptors, and isotope fractionation during the transformation process was studied. These findings demonstrate a potential tool for differentiating TCM degraders in field studies.

Summary: Microbial CO oxidation contributes to global carbon cycling and serves as a remover of toxic CO. Some microbial CO oxidizers have sister relationships with non-CO oxidizers. We discovered a versatile CO oxidizer, Parageobacillus sp. G301, capable of anaerobic and aerobic CO oxidation using both types of CODH. Comparative genomic analysis suggests that CO oxidation genes are not essential in the genus Parageobacillus.

Summary: Phytic acid is a potential alternative to dwindling rock phosphate as an organic phosphorus source, but due to its insolubility, it is not readily available for plants and monogastric livestock. Therefore, the search for phytase-producing microbes has become a research focus in agriculture and animal feed industries. This study isolated four fungal strains that exhibited phytase activity and identified their suitability for industrial applications.

Summary: In this study, microorganisms that can transform and cleave the ether bond of 2-phenoxyacetophenone, a model compound for the beta-O-4 linkage in lignin, were isolated and characterized. Among them, Acinetobacter sp. TUS-SO1 efficiently and selectively cleaves the ether bond of 2-phenoxyacetophenone. These microorganisms may play important roles in the degradation of lignin-related compounds in nature.

Summary: In this study, two DON-degrading bacterial strains, Bacillus sp. HN117 and Bacillus sp. N22, were isolated and characterized. Both strains were able to efficiently degrade DON in a wide range of temperatures and concentrations. The degradation products included a new isomer and potential low-toxic derivatives. These strains have the potential to be used as biodegrading agents to control DON contamination in food and feed industries.

Summary: A novel heterotrophic nitrification and aerobic denitrification strain CY-10, identified as Sphingopyxis sp., was isolated. The strain exhibited different nitrogen removal efficiencies when ammonium, nitrate, or nitrite were used as the sole nitrogen source. The optimal salinity for ammonia nitrogen removal was found to be 0-5%, and the strain showed increased metabolic levels of sucrose and D-tagatose at 5% salinity condition. The functional genes and pathway of HN-AD were successfully identified, suggesting the potential of strain CY-10 in nitrogen removal treatment of saline wastewater.

Summary: The study identified a microorganism called DCMF that can transform toxic dichloromethane into environmentally benign acetate in anaerobic environments. Through stable carbon isotope experiments, it was shown that DCMF assimilates carbon from DCM and bicarbonate via the Wood-Ljungdahl pathway. DCMF is the first anaerobic population known to degrade dichloromethane, while also metabolizing non-chlorinated substrates.

Summary: Polychlorinated dibenzo-p-dioxins and furans (PCDD/F) are highly toxic compounds that are difficult to degrade in the environment. This study focuses on the PCDD/F contamination in Sydney Harbour Estuary, with the contamination source area in Homebush Bay being one of the most heavily polluted sites in the world. The researchers found evidence of attenuation of the most toxic congener, 2,3,7,8-TCDD, at the source area. They also discovered a significant population of Dehalococcoidia and Dehalobium, which played a role in the microbial dechlorination of PCDD/F.
