Summary: This study determined the taxonomic status of four genetic groups of Flavobacterium columnare using polyphasic and phylogenomic approaches. Phylogenetic analyses demonstrated that the four genetic groups formed well supported and distinct clades within the genus Flavobacterium. Biochemical and physiological characteristics were similar among the groups, but quantitative differences in fatty acid profiles were detected and MALDI-TOF analyses showed unique peaks for each group. Therefore, the names F. covae sp. nov., F. davisii sp. nov., and F. oreochromis sp. nov. are proposed for genetic groups 2, 3, and 4, respectively.

Summary: Soil amendment is a promising strategy to enhance the biodegradation capacity of indigenous bacteria. Different soil amendments have varying effects on diesel degradation efficiency and bacterial communities, with nutrients and biochar amendments showing potential to improve biodegradation and soil physiological functions. Bacterial diversity decreases and potential diesel-degrading bacteria appear in response to soil amendments, while surfactants, oxidants, and iron nanoparticles may reduce diesel degradation efficiency.

Summary: This study investigated the mechanisms controlling the reduction of mercury (Hg) bioavailability in activated carbon (AC) amended estuarine sediments. The results showed that AC amendment decreased Hg bioavailability not only through physicochemical sorption, but also by changing geochemical species and shifting the microbial community composition. These findings are important for managing and remediating Hg contaminated sediments.

Summary: This study investigated the seasonal trends in bioaccumulation potential and toxic effects of mercury in Asian clams and microbial community. The results showed that mercury accumulation in clams and pore water was highest during the summer season at contaminated sites. The upregulation of biomarker genes in clams indicated their response to mercury contamination. High levels of mercury negatively affected bacterial and metabolic diversities.

Summary: Metal contamination and other geochemical alterations disrupt microbial composition and functional activities, leading to disturbances in biogeochemical cycles. This study investigated the distribution of total mercury (THg), methylmercury (MeHg), and trace metals in anthropogenically affected sediment. The microbial communities and functional gene profiles were analyzed to explore their relationship with Hg-methylation and geochemical features. Results showed that THg and MeHg levels increased towards the lower horizons of the sediment cores, while Al, Fe, Mn, and Zn were the major metals present at all depths. The enrichment and contamination indices indicated high concentrations of trace metals in the anthropogenically affected sediment. Various functional genes and dominant microbial taxa were detected, with correlations between major taxa and geochemical variables suggesting the significant impact of sediment geochemistry on microbial communities and biogeochemical cycles. Archaeal methanogens and bacterial phyla Chloroflexi and Firmicutes were also implicated in the enhancement of MeHg levels. Overall, these findings provide insights into the microbial communities involved in Hg-methylation process and other biogeochemical cycles.
