Abstract:
A chitinolytic fungus, Beau6eria bassiana was isolated from marine sediment and significant process parameters influencing
chitinase production in solid state fermentation using wheat bran were optimised. The organism was strongly alkalophilic and
produced maximum chitinase at pH 9·20. The NaCl and colloidal chitin requirements varied with the type of moistening medium
used. Vegetative (mycelial) inoculum was more suitable than conidial inoculum for obtaining maximal enzyme yield. The addition
of phosphate and yeast extract resulted in enhancement of chitinase yield. After optimisation, the maximum enzyme yield was
246·6 units g 1 initial dry substrate (U gIDS 1). This is the first report of the production of chitinase from a marine fungus.

Abstract:
Extracellular L-glutaminase production by Beau6eria sp., isolated from marine sediment, was observed during solid state
fermentation using polystyrene as an inert support. Maximal enzyme production (49.89 U:ml) occurred at pH 9.0, 27°C, in a
seawater based medium supplemented with L-glutamine (0.25% w:v) as substrate and D-glucose (0.5% w:v) as additional carbon
source, after 96 h of incubation. Enzyme production was growth associated. Results indicate scope for production of salt tolerant
L-glutaminase using this marine fungus
