Study of Isolated Marine Bacteria For Various Applications

Bacterial isolates were isolated from marine environment of Mumbai beaches and were screened for various biotechnological applications viz . antibacterial activity, production of extracellularenzymes, production of PHB, tolerance of heavy metals and degradation of biologicaldyes. A total of twenty six bacteriawere isolated in pure culture form and their biotechnological potential was studied.These isolates were checked forvarious enzyme production namely, Protease, Lipase, Amylase, Cellulase, β-Galactosidase and Pectinase. 6 isolates showed activity against S.aureus whereas 2 isolates showed activity against E.coli . 8 bacterial isolates were positive for PHB production. The marine bacteria showed the potential to tolerate heavy metals viz. lead and chromium and were able to decolourize and degraded biological dyes. The study has overall concluded that marine bacteria could serve as potential bioresources for many biotechnological applications.
