Abstract

Mixed culture of Trichoderma reesei and Aspergillus niger was investigated to optimize the cellulase components in liquidstate fermentation. A mode of delayed inoculation was applied for cocultivation of T. reesei and A. niger. After cultivation of T. reesei for 48 h, A. niger was inoculated at the 1∶1 inoculum ratio. The βglucosidase activity and filter paper activity of the mixed fungi culture were 0.606 μmol/(min·mL) and 1.163 μmol/(min·mL), respectively, corresponding to a ratio of 0.521, which was higher than that of T. reesei under single cultivation. The yield of enzymatic hydrolysis was 65.61 % by the cocultivated cellulase, which was higher than those of singlecultivated cellulase and commercial cellulase. These results demonstrated that cocultivation of T. reesei and A. niger was suitable for optimization of cellulase components.
