Abstract The effects of surfactants on the production of cellulase by Trichoderma viride in liquid substrate fermentation process were investigated in this study. Straw was used as the sole carbon source and the surfactants were biosurfactant rhamnolipid from Pseudomonas aeruginosa and Tween 80. The changes of FPA, CMCase, Avicelase and surface tension with time were analyzed under different concentrations of the two surfactants. The results showed that the surfactants can enhance the enzyme activity of Trichoderma viride. The FPA, CMCase, Avicelase were promoted 1.08, 1.6 and 1.03 times higher than the controls by rhamnolipid. The enhancement of the enzyme activity by rhamnolipid was much higher than that of Tween 80. At the same time, rhamnolipid was not degraded prior to other substrate.

Key words： Tween 80 cellulase Trichoderma viride rhamnolipid
