Effect of biosurfactants on degradation of organics containing petroleum hydrocarbons in composting

Biosurfactants were introduced into composting process. Aerobic composting amended with petroleum hydrocarbons was adopted to simulate the hydrocarbon contaminated composting process. Two different biosurfactant broths were added to the composting and their effects on the degradation of hydrocarbons were compared with the control. The result show that the biosurfactants can not only improve the composting but also enhance the degradation of hydrocarbons in composting, and the effect of rhamnolipid broth is better than surfactin one.
