Preliminary study on enzymological characteristics of xanthan-degrading enzyme
A xanthan-degrading enzyme was prepared from Xanthan-degrading bacteria Paenibacillus lautus XD2-8,and its enzymological characteristics were preliminarily studied as well in this paper.The results showed that the optimum temperature is at 35 ℃,the optimum pH is 6.0 and the optimum substrate concentration is 5 g/L.Glucose has an inhibitory action on the enzymatic reaction,and the action was enhanced with the increase of glucose concentration.
