Characterization of novel extracellular protease produced by marine bacterial isolate from the Indian Ocean.

ABSTRACT: Out of the vast pool of enzymes, proteolytic enzymes from microorganisms are the most widely used in different industries such as detergent, food, peptide production etc. Several marine microorganisms are known to produce proteases with commercially desirable characteristics. We have isolated nine different cultures from marine samples of the Indian Ocean. All of them were i) motile ii) rod shaped iii) non spore forming iv) catalase and amylase positive v) able to grow in presence of 10 % NaCl. They produced acid from glucose, fructose and maltose and grew optimally at 30 °C temperature and pH 7.0-8.0. None of them could grow above 45 °C and below 15 °C. Only one of them (MBRI 7) exhibited extracellular protease activity on skim milk agar plates. Based on 16S rDNA sequencing, it belonged t
