Production of bioethanol from wheat straw via optimization of co-culture conditions of Bacillus licheniformis and Saccharomyces cerevisiae

Abstract Bioethanol production has been a challenge for the researchers with respect to enhancing bioethanol yield. In this study, we are reporting an efficient novel method produce bioethanol. The process comprises co-culture technique from wheat straw, by co-culturing Bacillus licheniformis and Saccharomyces cerevisiae. Simultaneous saccharification fermentation allows straw hydrolysis cellulase enzyme produced conversion of reducing sugar into ethanol cerevisiae . Pre-treatment optimization parameters like, time, pH, substrate concentrations nitrogen source gave net yield ? 4.11 g/l Scale up optimised media fermenter resulted in significant enhancement 14.70 g/l.
