Tannin acyl hydrolase production by Citrobacter sp. isolated from tannin rich environment, using Tamarindus indica seed powder.

Bacterial isolate, Citrobacter sp., from tannery effluent loaded sites has proved as a potent producer of tannase. Production of tannase was compared in solid-state and submerged fermentation using tamarind seed as sole carbon source. Two times increase in tannase activity was seen in solid-state fermentation (90 U) than submerged fermentation (50 U) at 48 h from 5 g substrate.
