The effect of junlon PW110 and tween 80 on the production of cellulolytic enzymes by Coprinus cinereus

The effect of Junlon PW110 (an acrylic acid polymer) and of Tween 80 (a nonionic surfactant) on the production of cellulolytic and xylanolytic enzymes by the basidiomycete fungus Coprinus cinereus was investigated. The inclusion of each material in culture media resulted in significant increases in the production of extracellular cellulases and a mixture of the two was even more effective. Junlon PW110 also stimulated growth of C. cinereus and the production of xylanase and β-xylosidase. Tween 80 had no effect on xylanase production although it did increase β-xylosidase production. Junlon PW110 and Tween 80 in combination increased the rate of production of cellulase by cultures as well as its final yield.
