A COMPUTATIONAL GENOME ANALYSIS OF STRAIN BACILLUS SUBTILIS MIZ-8 ISOLATED FROM BEKANG REVEALS A DISTINCT CHROMOSOME AND PLASMID CONFERRING SELECTIVE ADVANTAGE
Keywords:Bacillus subtilis, Bekang, fermented food, Whole genome sequencing
Bacillus subtilis Miz-8 is isolated from Bekang, a traditional fermented soybean food of Mizoram, India. Here, we report computationally analyzed strain Miz-8 mapped to the annotated genome of the reference strain Bacillus subtilis subsp. natto BEST195. Miz-8 has a circular chromosome and a small plasmid with genome size of 4105264 bp and 5838 bp, respectively. Genome contains the genes responsible for synthesis of biosynthetic metabolites like surfactin, fengycin, bacillibactin, bacilysin, subtilosin A and alpha amylase production. The strain Miz-8 harbored virulence genes identical to the strain BEST195 render themselves harmless for human consumption. However, Strain Miz-8 has one intact prophage region but no integrase protein, making it incapable of lateral transfer of antimicrobials. Antibiotic resistance genes were predicted among which tmrB gene was on perfect hit. Plasmid of strain Miz-8 contains no prophage sequences and antibiotic resistance genes. Furthermore, there were several single nucleotide polymorphisms and 344 insertion-deletion polymorphisms. Bacillus subtilis Miz-8's genomic information unmasks its functional significance on human health.
