ABSTRACT

Tannin acyl hydrolase (E.C.3.1.1.20) is usually called as tannase, which hydrolyses the ester and depside bonds of tannins and gallic acid, glucose and galloyl esters are the end products. The enzyme tannase had many applications in many industrial areas like food, pharmaceutical, chemical and beverages. The enzyme has potential uses in the treatment of tannery effluents and pre-treatment of tannin containing animal feed. With a long historical evidences and scientific publications, tannase is still considered as one of the costly industrial enzymes. In view of the growing demand, it is imperative to isolate high productive strains and develop economically feasible processes. The present study is concentrating on the isolation and screening methods of tannase enzyme from fungal source.
