摘要：

The potential of gallotannin, methyl gallate, gallic acid, and pyrogallol to induce tannin acyl hydrolase (EC 3.1.1.20) activity in Aspergillus niger, Aspergillus fischerii, Fusarium solani, and Trichoderma viride has been investigated. The maximum induction ratios recorded were A. fischerii (26.7), F. solani (26.1), and T. viride (40.7) when the fungi were induced with gallotannin, gallic acid, and methyl gallate, respectively. A. niger was devoid of basal enzyme activity. The gallotannin tolerance limits for A. niger, A. fischerii, F. solani, and T. viride were determined by progressively increasing the gallotannin concentration and were found to be 20, 4, 3, and 3%, respectively. F. solanii induced with 3% gallotannin has been recommended for the production of tannase enzyme. (C) 1997 by Elsevier Science Inc.
