%X The effect of dirhamnolipid biosurfactant on degradation of straw lignocellulose by white rot fungi in solid state fermentation was studied. The results showed that dirhamnolipid at different concentrations was able to enhance the lignin degradation. Dirhamnolipid at 0.007% and 0.021% (w/w) increased the released water soluble total organic carbon (TOC) by 83.6% and 54.5%, respectively, which provided an opportunity of increasing the growth of Phanerochaete chrysosporium and decreasing its degeneration. In addition, the maximum activity of lignin peroxadase (LiP) was increased by 85.7% with dirhamnolipid at 0.007% (w/w). Whereas, dirhamnolipid have no stimulative effects on manganese peroxidase (MnP) activity. The degradation rate of lignin was increased by 54% with rhamnolipid at 0.007% (w/w) compared to the control.
