Bioethanol production from Jatropha seed cake via dilute acid hydrolysis and fermentation by Saccharomyces cerevisiae

The interest in using Jatropha curcas L. as a feedstock for the production of bio-diesel is rapidly growing. Available literatures holds [promise simultaneous wasteland reclamation capability and oil yields plant hence fueling bio-ethanol hopes. This research investigated bioconversion cellulose from press cakes seeds, which byproduct biodiesel plant, into ethanol by methods acid pretreatment, hydrolysis fermentation Saccharomyces cerevisiae. process includes pretreatment method finely ground cellulosic solid oilseed cake with dilute sulphuric heating mixture at high temperature to break crystalline structure lignocellulose facilitate component acids. About 63.33% was recovered confirmed infra-red spectroscopy physicochemical parameters show that produced bioethanol promise its use possible candidate replacement petroleum diesel.
