Summary: The number of reported plastic-degrading microorganisms is increasing rapidly, allowing for exploration of plastic-degrading traits conservation and distribution across diverse microbial classifications. Strong evidence was found for the degradation of the synthetic polymer polylactic acid (PLA), and related microbial species are phylogenetically conserved. A total of 16,170 putative plastic degradation orthologs were identified in microbial genomes, showcasing vast potential for further research. The comprehensive database and interactive phylogenetic tree created will aid in understanding genetic diversity and evolution of microbial plastic-degrading capabilities.

Summary: Utilizing rumen microorganisms for anaerobic fermentation of corn straw to produce VFAs is important for biomass valorization, with VFA concentration reaching 8.99g/L within 72 hours. The bacterial and fungal community composition dynamically changed, but the core genera remained stable. Factors such as low pH and VFA accumulation had significant effects on bacterial and fungal communities.

Summary: In this study, a nornicotine-degrading consortium was enriched from a river sediment sample and characterized using metagenomic sequencing. Mycolicibacterium sp. strain SMGY-1XX, which has not been previously reported to degrade nornicotine, was found to be capable of degrading nornicotine, nicotine, and myosmine. The study identified candidate genes responsible for nornicotine degradation in Mycolicibacterium sp. strain SMGY-1XX through genomic, transcriptomic, and proteomic analysis. These findings provide new insights into the microbial catabolism of nornicotine and nicotine and offer potential applications for the removal, biotransformation, or detoxification of nornicotine.

Summary: 52 nicotine-degrading bacterial strains were isolated from tobacco soil, with Flavobacterium, Pseudomonas, and Arthrobacter as the dominant genera. Two efficient strains, Arthrobacter nitrophenolicus ND6 and Stenotrophomonas geniculata ND16, were screened and successfully inoculated into compost from tobacco waste, reducing nicotine concentration below the safety threshold. Metagenomic analysis revealed a positive correlation between the abundance of nicotine-degrading genes and soil nicotine concentrations. The findings highlight the potential applications of nicotine-degrading bacteria and key genes in environmental monitoring and composting of tobacco waste.
