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.
