摘要：An integrated approach was studied for in-house cellulase and xylanase production, from novel hyperhydrolytic enzyme producers and enzymatic hydrolysis of alkaline hydrogen peroxide pretreated Populus deltoideswood into bioethanol. Fermentation of lignocellulosic hydrolysate was performed under simultaneous saccharificationand fermentation (SSF) and simultaneous saccharification and co-fermentation (SSCF) using different yeasts viz.Saccharomyces cerevisiae I, Saccharomyces cerevisiae II, Pichia stipitis, Candida shehatae and Zymomonas mobilis asmonoculture and co-culture combination. Maximum 11.26 g/l ethanol yield achieved with co-culture of S. cerevisiae II+ P. stipitis with fermentation efficiency of 44.16% under SSF. While SSCF was performed by a recombinant strain ofClostridium thermocellum strain DSM 1313. Co-culture combination of S. cerevisiae II + P. stipitis was applied forscale up process of bioethanol in a stirred tank bioreactor.
