Extremozyme Production by Extremely Halophilic Bacterial Strains isolated from Saline/Hypersaline Environments

M. Jothi Basu, V. Indra, S. Vijayanand

Abstract :

The extracellular hydrolytic enzyme production profile of the 16 isolated bacterial strains was achieved by testing their ability to hydrolyze various substrates such as casein, gelatin, starch, Tween-80, and RBB-xylan. Casein and gelatin hydrolyzing enzyme activity was observed in 4 strains (MJS1, JS-4, BB1 and BB2). Strains MJS2 and BC2 showed amylase activity. Lipolytic activity was exhibited by 3 halophilic bacterial isolates (JS-1, JS-5, and BC2). Three isolates including MJS4, BC1 and JS-3 hydrolyzed xylan. Majority of the isolates (68%) showed their potential to hydrolyze atleast one of the above mentioned substrates while some strains (32%) failed to hydrolyze none of the substrates.
