Tannase is an industrially important enzyme and has several applications in various industries such as foods, animal feeds, cosmetics, pharmaceutical, chemical, leather industries etc. The enzyme has potential uses in the treatment of tannery or industrial effluents. Despite the long history and numerous publications, tannase is still considered as one of the costly industrial enzymes. The aim of this study was to isolate a tannase-producing fungus from industrial effluents and evaluate its tannin degrading properties. In the present study tannase producing fungi were isolated from soil nearby tannery industries. Twenty-six isolates of tannase-producing fungi were isolated and were screened using tannic acid agar plate method. Zone of hydrolysis confirmed their Tannin degrading ability. Ninteen isolates were screened as tannase producers. Accordingly, Four Isolates, which exhibited high tannase activity, were chosen to undergo final screening. Study suggested that the tannase isolated from fungi can for tannin biodegradation in the industrial effluents.
