Metagenome of a Microbial Community Inhabiting a Metal-Rich Tropical Stream Sediment
TLDR
A high metabolic diversity was detected in the MSS, suggesting that the historical arsenic contamination is no longer affecting the prokaryotic community and expanding the current knowledge of the microbial taxonomic and functional composition of tropical metal-contaminated freshwater sediments.

Novel arsenic-transforming bacteria and the diversity of their arsenic-related genes and enzymes arising from arsenic-polluted freshwater sediment
TLDR
The role of freshwater sediment bacteria in arsenic mobility, and the untapped diversity of dissimilatory arsenate-reducing and arsenates-resistant bacteria, which might contribute to arsenic toxicity in aquatic environments are highlighted.

Genotypic and phenotypic diversity of Bacillus spp. isolated from steel plant waste
TLDR
Isolates with identical 16S rRNA gene sequences had different genomic fingerprints and differed considerably in their physiological capabilities, so the high levels of phenotypic diversity found in this study are likely to have ecological relevance.

Insights into the skin microbiome dynamics of leprosy patients during multi-drug therapy and in healthy individuals from Brazil
TLDR
Genus-level compositional profiles revealed no significant intrapersonal difference between lesional and non-lesional sites, and treatment-associated changes indicated a loss of diversity and a shift in the community composition, with stronger impacts on the OTUs that are considered indigenous bacteria.

The Microbiota and Abundance of the Class 1 Integron-Integrase Gene in Tropical Sewage Treatment Plant Influent and Activated Sludge
TLDR
The analysis of 1,174,486 quality-filtered reads obtained from RS and AS samples revealed complex and distinct bacterial diversity in these samples, emphasizing the importance of biological treatment for diminishing pathogenic bacteria and those bearing the intI1 gene that arrive at a sewage treatment plant.

Molecular bacterial diversity and distribution in waste from a steel plant.
TLDR
The results indicate that the bacterial communities in steelmaking wastes present high phylogenetic diversity and complexity, and six previously unclassified OTUs may represent novel taxa.

Analysis of Chromobacterium sp. natural isolates from different Brazilian ecosystems
TLDR
The physiological analyses clearly demonstrate the high biochemical versatility found in the C. violaceum genome and molecular methods allowed to detect the intra and inter-population diversity of isolates from three Brazilian ecosystems.
