Kinetic study of enzymatic hydrolysis of tannins

Abstract:

Tannins are present in many plant foods. Tannase (EC 3.1.1.20) catalyses hydrolysis of ester bonds in hydrolysable gallotannins releasing glucose and gallicacid. Enzyme was produced by Penicillium chrysogenum cultured in Czapek-Doxmedium containing tannic acid. The tannic acid was used as a substrate in theenzymatic reactions. The product inhibits the enzymatic reaction. It was determined that inhibition was of the competitive type. The mathematical model(Eg. 7) and kinetic constancy describing the process were determined:Km = 0,53-10 ‘'|mol/dm3), Rm = 1,2610-3 (mol/dm^minj, Kp=2,04-10-'* (mol/dm^j.The results obtained from the model well agree with those obtained experimentally.
