Title
Effects of Tween 80 and rhamnolipid on the extracellular enzymes of Penicillium simplicissimum isolated from compost
Abstract

Extracellular enzymes of microorganisms play an important role in the decomposition of macromolecules in the composting process. In this study, the effects of Tween 80 and rhamnolipid on the extracellular amylase, carboxymethyl cellulose enzyme (CMCase), xylanase and protease of Penicillium simplicissimum isolated from compost were investigated during solid-state fermentation. The results showed that the enzyme activities of amylase, CMCase and xylanase were increased by Tween 80 and rhamnolipid, which, however, had a negative effect on the protease production. The stimulative effects on the three enzymes were quite different during the whole fermentation process. Tween 80 and rhamnolipid also increased the fungal biomass slightly. As a result of the enhanced enzyme activities, the organic matter were also improved to different extents by both surfactants, and the decomposition rates of hemicellulose and cellulose were increased about 8.0% and 11.6% by Tween 80 at best, respectively, as well as 5% and 5.5% by rhamnolipid.
