Marine sediments are attracting attention for exploring industrially useful enzymes. Marine microorganisms are a valuable source of novel enzymes with ideal characteristics because of the halophilic nature of the marine bacteria.. Microbial enzymes are gaining more importance in the modern industrial world which can degrade complex compounds into simpler substances, and play an important role in industries. The aim of the present study is the isolation and screening of the marine bacterial strains which produce industrially important enzymes like amylase and protease. Marine sediment samples were collected and a total of seven bacterial strains were isolated and two of these five strains were showed to be amylase producers. Among the six isolates, only one isolate showed maximum proteolytic activity with a clear zone in skim milk agar. Whereas the other five isolates exhibited poor proteolytic activity . Morphological and biochemical characterestics of amylase and protease producing organisms were done. The study concludes that marine bacteria can be a source of amylase and protease for industrial purposes.
