Studies on Isolation of Marine Bacterium Producing Low - temperature Alkaline Protease

Sampled from marine fishes and shells, producing protease strains are isolated with enriching medium , casein isolating medium and proteolytic casein test. The resiJt indicates that marine bacteria producing low - temperature alkaline protease can be isolated in samples of marine fish and shells. Casein isolating medium is better isolating medium. The strain producing protease can make proteolytic circle in it. Protease activity can be determined by Proteolytic Casein Test . The strain producing high protease activity can make larger proteolytic circle. Combined casein medium and Proteolytic Casein Test were used in isolating of marine bacteria producing low - temperature alkaline protease can raise efficiency of isolation.
