Summary: The study analyzed the community structure of deep-sea polychaetes in the northwest Atlantic, revealing three major groups with differences that can be explained by environmental gradients and long-term variables. It was found that energetics and habitat structure were significant factors influencing polychaete communities, while historical fishing intensity had a weaker effect. The impact of long-term environmental factors suggests that the deep sea is vulnerable to climate change and should be considered in future ecosystem management.

Summary: In 2015, a collapse of a mine dam in the Southwest of Brazil resulted in the release of millions of tons of sediments into an estuary. The contaminated soil is still highly polluted with metals, possibly leading to the selection of microorganisms capable of surviving in such harsh conditions. In this study, we isolated metal(loid) and antibiotic resistance bacteria from the polluted estuarine soil. After identifying the strains through 16S rDNA sequencing, we focused on the Mucilaginibacter sp. strain due to its potential as a bioprospector and its high resistance profile. We successfully obtained the complete genome of this strain and conducted a genome-guided characterization. Our findings suggest that the strain 21p may be a new species of the genus, exhibiting resistance genes for metals and cross-resistance for antibiotics. Further exploration of the Mucilaginibacter sp. 21p as a new species is warranted, considering its extracellular polymeric substances and its potential for bioremediation and growth promotion in highly metal(loid)-contaminated soil.
