Fungal Production of Tannase:A Review

Tannin acyl hydrolase (E.C.3.1.1.20) is commonly referred as tannase, hydrolyses ester and depside bonds of hydrolysable tannins to produce gallic acid, glucose and galloyl esters. Tannase has many industrial applications. The enzyme has potential uses in the treatment of tannery effluents. A lot of research is done on production aspects of tannase, but is still considered as one of the costly industrial enzymes. This is due to less yields and long fermentation time of the processes. In view of the growing demand, it is important to isolate high productive strains and develop economically feasible processes. This study reviews the fungal sources, screening methods, modes of production, temperature and pH of fermentation of tannase enzyme.
