Effect of environmental temperature on formation of cellulase and xylanase in Thricholomataceae L1

Abstract

Abstract: Higher environmental temperature is beneficial to the growth of Tricholomataceae L1 and its protein synthesis. When temperature is 38℃, the specific activity of cellulase is the highest, reaching 23.4Iu·mg^-1 protein. After cultivated for 93 hours at this temperature, its cellulase activity is 33Iu·g^-1 dry medium. The optimal temperature for the formation of xylanase is 32℃. Under this temperatrue, the specific activity of xylanase is 92Iu·mg^-1 protein, and after cultivated for 67 hours, it is 126Iu·g^-1 dry medium. It is suggested that environmental temperature has a regulation effect on the formation of intracellular enzyme of Tricholomataceae L1.
