Statistical optimization of ethanol-based biodiesel production from sludge palm oil using locally produced candida cylindracea lipase

Face centered central composite design was used to optimize the enzyme loading, reaction temperature and mixing speed of sludge palm oil (SPO) transesterification reaction using locally produced Candida cylindracea lipase. The developed quadratic model was found to be significant at p < 0.05. The...
