CONCLUSION
Bacillus mycoides NR5 isolated from polluted Nag River demonstrated presence of high arsenic tolerance. The primary mechanism of As resistance in NR5 was observed as biosorption. Whereas, the silver nitrate assay indicated arsenate reduction potential of NR5 and subsequently the amplification of arsenate reductase gene arsC 1 in NR5 genome also suggested possible role in arsenic tolerance in NR5. Moreover, B. mycoides NR5 also possess attributes pertaining plant growth promotion by producing Siderophore, IAA, nitrate, ammonia production and phosphate solubilization, hence, is an appropriate choice for application in crop plants for reduction in uptake of As in plants and also promote growth for sustainable environment.
