Abstract: Actinomycetes were isolated from marine sediments of Cape Comorin coast (Lat.8° 21’ N and Long 77° 30’E), India for extracellular L-glutaminase production. Out of 25 isolates screened, the strain Streptomyces sp.-SBU1 showed promising L-glutaminase activity. Maximal L-glutaminase activity (18.0 U/ml) was observed in a medium supplemented with 2% NaCl (w/v) and 1% malt extract (w/v) as nitrogen source, 1% glucose (w/v) as carbon source, the initial pH of 9.0 at 30°C after 96 h of incubation was found to be optimal culture condition by the strain Streptomyces sp.-SBU1. So for only few marine actinomycetes have been explored for their L-glutaminase production. Hence the present study was initiated to optimize the media composition for L-glutaminase production.
