Abstract
Streptomyces spp. isolated from the gut of fish, Therapon jarbua and shellfish, Villorita
cyprinoids exhibited L-asparaginase activity under growing conditions in a liquid broth.
Streptomyces AQBTJ 60 (isolate from fish) showed maximum enzyme activity at pH 8.0 whereas
Streptomyces AQB VC67 showed it at pH 7.0. They showed optimum enzyme activity and
growth at temperature 370C. Carbon sources and amino acids had varying influence based
on the constituents in the gut or viscera of the host organisms and heavy metals inhibited
activity and growth. Similar trend was noticed with sodium chloride in the estuarine strains.
