Fermentation of Jatropha curcas solid waste with Aspergillus niger

Abstract

An experiment has been carried out by using Jatropha curcas solid waste as substrate for fermentation with Aspergillus niger. Enzyme production from the fermentation activities and the toxicity level i.e. phorbol ester contents of the biomass were determined. The results suggested that the utilization of Jatropha solid waste as substrate for enzyme production could be an alternative in replacing its traditional used as fodder or fertilizer especially when there is no practical way for its detoxification
