Useful Extracellular Activity of Bacteria Isolated from Bhitarkanika Mangrove Ecosystem of Orissa Coast

Abstract

This paper describes the isolation of bacteria from Bhitarkanika mangrove ecosystem of Orissa and screening for their antifungal properties against five pathogenic fungi, extracellular enzyme activity like amylase, protease and lipase, and phosphate solubilization capacity. From 567 bacterial isolates obtained, 26 bacterial isolates have exhibited wide spectrum antifungal activity against all five fungi tested. Most of the bacterial isolates were found to be amylase and protease producers. In present study, 41 lipase producers and 33 phosphate solubilisers were also found. Bacterial isolates from plant origin exhibited all the four extracellular enzyme activity except lipase. The maximum % occurrence of phosphate solubilisers was found in soil and plant system of mangrove. This screening study opens an avenue to work with some of the potent strains for useful product formation at large scale.
