Microbial enzymes have been used in various industries for many centur
ies. Recently, with the advent of biotechnology, there has been a grow
ing interest in and demand for enzymes with novel properties. Currentl
y, microbes from terrestrial sources are employed for industrial produ
ction of enzymes, although the potential for synthesis of several nove
l enzymes by marine microorganisms has been recognized. In India, over
the past two decades, a number of studies have been made on detection
of enzymes including phosphates, arylsulfatase, chitinase, L-asparagi
nase, L-glutaminase, amylase, protease, Lipase, cellulase, urease, and
lactamase produced by marine bacteria, cyanobacteria, and funji. Howe
ver, their large-scale production was not attempted. In our laboratory
we have optimized production of L-glutaminase, an antileukemic and fl
avor-enhancer, by marine Vibrio costicola and Pseudomonas fluorescens;
and chitinase by Pseudomonas pseudomallei and Streptoverticillium sp.
, employing both submerged and solid-state fermentation processes. Res
ults suggest that there is scope for industrial production of these en
zymes.
