“…The JaH strain was a new Bacillus species and was called Bacillus vedderi showing the potential importance of this bacteria in biotechnological processes. The same species studied for Agnew et al [26] were isolated for Nogueira et al [21], showing the dominance of this group in the bauxite residue. The three strains isolated from Bauxite residue in the Southern region of Minas Gerais, Brazil [21] called BRA1, BRA3 and BRA5 were identified as B. cohnii, B. pseudofirmus and B. clarkii, respectively.…”

“…One of the strategies to try to find a solution to this problem regarding bauxite residue treatment is microbiological treatment. The use of alkaliphilic microorganisms is considered an attractive alternative method for treating industrial alkaline residues, owing to their ability to metabolically reduce alkalinity and their tolerance of high concentrations of ions and metals and low availability of organic carbon and nutrients [21].…”

“…This group has many adaptations to survive at high pH values. For example, they can maintain a cytoplasmic pH significantly lower than the highly alkaline external through continuous availability of cation efflux [22], and they can also produce acids in order to neutralize the high pH [21]. Bioremediation uses these metabolic properties of microorganisms to solve the problems of residue treatment.…”

Brown mud, as a waste product of the industrial process of aluminum production, represents a great environmental burden due to its toxicity to living organisms. However, some microorganisms are able to survive in this habitat, and they can be used in bioremediation processes. Traditional cultivation methods have a limited capacity to characterize bacterial composition in environmental samples. Recently, next-generation sequencing methods have provided new perspectives on microbial community studies. The aim of this study was to analyze the bacterial community in the drainage water of brown mud disposal site near Žiar nad Hronom (Banská Bystrica region, Slovakia) using 454 pyrosequencing. We obtained 9964 sequences assigned to 163 operational taxonomic units belonging to 10 bacterial phyla. The phylum Proteobacteria showed the highest abundance (80.39%) within the bacterial community, followed by Firmicutes (13.05%) and Bacteroidetes (5.64%). Other bacterial phyla showed an abundance lower than 1%. The classification yielded 85 genera. Sulfurospirillum spp. (45.19%) dominated the bacterial population, followed by Pseudomonas spp. (13.76%) and Exiguobacterium spp. (13.02%). These results indicate that high heavy metals content, high pH, and lack of essential nutrients are the drivers of a dramatic reduction of diversity in the bacterial population in this environment.
