Abstract

Abstract: Kinetic characteristics of valonia tannin biodegradation using natural microorganism groups were studied.Kinetic equation followed by biodegradation process of valonia tannin was obtained.It was found that temperature is the key factor influencing degradation rate of valonia tannin;rise of temperature within 10-35℃ range leads to increase of biodegradation rate,whilst the lag phase of degradation is shortened.Optimal temperature for degradation is 28-32℃.The effect of tannin concentration on the lag phase of biodegradation is significant at lower temperature,but negligible at temperature higher than 28℃.

Key words: vegetable tannins, valonia tannin, biodegradation, kinetics
