Abstract

Alkali, acid and hydrogen peroxide pretreatments were compared for their effect on lignin removal from water hyacinth, among them alkali pretreatment gave good results as compared to others. The highest sugar content in alkali pretreated samples was observed in water hyacinth treated with 5% NaOH solution at 20 psi pressure for 20 minute is 97.50%. Whereas the acid pretreatment had less effect on conversion of lignocellulose in water hyacinth to sugar is 80.6% at the same pressure and time. For hydrogen peroxide pretreatment it is around 67.00%. In this study, we have demonstrated the suitability of physical pretreatment under high pressure and temperature for production of fermentable sugar. Morphology inspection had also provided evidences of structure disruption that led to higher sugar recovery from water hyacinth in alkali pretreatment process than acid and hydrogen peroxide pretreatment process under the same conditions.
