A factorial analysis study on enzymatic hydrolysis of fiber pressed oil palm frond for bioethanol production

Different technologies have been developed to for the conversion of lignocellulosic biomass to suitable fermentation substrates for bioethanol production. The enzymatic conversion of cellulose seems to be the most promising technology as it is highly specific and does not produce substantial amounts...
