Descrição: dc.descriptionToxic metal pollution in the Amazon is a serious problem that reduces the quality of water, soil, air, and consequently alters communities of fauna, flora, and microbiota, harming human health and well-being. Our aim was to determine the impact of toxic metals on the structure of the bacterial community associated with Diplopoda in the Amazon rainforest. Animals were kept in microcosms contaminated with cadmium (50 mg.kg−1), mercury (35 mg.kg−1) and no toxic metal (control). The intestinal and molting chamber microbiota were accessed by culture-dependent and culture-independent methods (16S metabarcoding). The cultivated strains were identified, and their functional traits evaluated: secretion of enzymes, growth at different pH, resistance to metals and antibiotics, and ability to reduce toxic effects of metals on plants. Our research described Brachyurodesmus albus, a new species of Diplopoda. We obtained 177 isolates distributed in 35 genera and 61 species of bacteria (Pseudomonadota, Bacillota, Bacteroidota and Actinomycetota) associated with the gut and molting chamber of B. albus. Metabarcoding data provided a more robust access to the bacterial community, resulting in 24 phyla, 561 genera and 6792 ASVs. The presence of metal Cd and Hg alters the composition and abundance of bacteria associated with B. albus (PERMANOVA p < 0.05). The microhabitat (gut and molting chamber) harbours bacterial communities that differ in composition and abundance (PERMANOVA p < 0.05). The presence of Cd and Hg alters important metabolic pathways related to the prokaryotic defense system; antimicrobial resistance genes, endocytosis and secretion system, estimated by PICRUSt. Bacteria selected with high resistance to Cd and Hg buffer the toxic effect of metals on tomato seedlings. This work describes B. albus and concludes that its diverse bacterial microbiota is altered by soil contamination by toxic metals, as well as being an important repository for prospecting strains to be applied in bioremediation programs.-
