Abstract:
In this thesis an attempt is made to explore the potential of marine fungi for the production of chitinolytic enzymes and to recognize the ability to hydrolyse native chitin through submerged as well as solid substrate fermentation culture conditions, using wheat bran and shellfish processing waste such as ‘prawn waste’ as solid substrates. Attempt was made to isolate a potential chitinase producing fungus from marine environment and to develop an ideal bioprocess for the
production ofchitolytic enzymes.Present study indicate scope for utilization of B. bassiana
for industrial production of chitinase using prawn waste as solid substrate employing solid substrate fermentation.

Abstract:
The study entitled standardization of optimum conditions for the production of glucosamine hydrochloride from chitin. Shellfish processing industries around the world turn out a significant quantity of head and shell as industrial waste. The waste must be removed immediately to prevent the contamination to the processing environment. The technique that are available for their disposal include ocean dumping, incineration or disposal of landfill sites. In this thesis the techniques and methods are used to process glucosamine hydrochloride from crustacean processing waste. Chitin is a nitrogenous polysaccharide, which is white, hard, inelastic, found in outer skeleton of insects, crabs, shrimp and lobsters and in the internal structures of other invertebrates. Glucosamine can be considered as a nutraceutical product by virtue of its properties. It is important for healthy skin, and plays a major role in the healing of surgical incisions and skin wounds. Deproteinisation of shrimp shell had significant effect on quality of chitin. Demineralization is also influences chitin quality. Solvents used for glucosamine hydrochloride affects the final yield and purity.
