Tannase production by Bacillus licheniformis

Bacillus licheniformis KBR 6 produced maximum extracellular tannase activity at 0.21 U ml(-1) with 1.5% (w/v) tannic acid either in the absence or presence of glucose (1 g l(-1)) after 18-21 h growth though the organism did not attain maximum growth until 36 h.
