Molecular and taxonomic characterization of arsenic (As) transforming Bacillus sp. strain IIIJ3–1 isolated from As-contaminated groundwater of Brahmaputra river basin India

摘要

Unrooted Neighbour Joining (NJ) phylogenetic tree based on 16SrRNA gene sequences of strain IIIJ3–1 and related Bacillus spp., a. consensus phylogenetic tree of strain IIIJ3–1 and all validly described type strains of Bacillus using the Jukes-Cantor distance model considering a total of 1485 positions in the final dataset, b. Phylogenetic relationship of strain IIIJ3–1 and other As transforming Bacillus spp. isolated from diverse As-impacted habitat with a total of 1490 positions in the final dataset. The black solid circle indicates the consistent tree topology obtained through both NJ and ML methods. Bootstrap values (percentage of 1000 replications) greater than 60% are represented at the nodes. The GenBank accession numbers are mentioned in the parentheses. Scale bar denotes the rate of nucleotide substitution
