Abstract: Bioethanol is
most widely used biofuel in the transportation sector as solely or blended with
gasoline. It is produced from carbohydrate substrate through microbial
bioconversion. Lignocellulosic substrate is most abundantly found carbohydrate
source in the earth for bioethanol production. Fermentation process mainly
depends upon the microbial capability to utilize both pentose and hexose sugars
found in the lignocellulosic substrate. Deoiled rice bran (DORB) is a
lignocellulosic industrial waste obtained from oil refinery after the
extraction of oil from rice bran. In this work, microbial co-cultures were
performed to ferment DORB for bioethanol in batch culture. Co-culturing of
Klebsiella oxytoca ATCC 13182 with Zymomonas mobilis MTCC 92 produced 74.9 g/l
of bioethanol from DORB estimated by Specific gravity method. The results
indicated that co-culturing of Klebsiella oxytoca ATCC 13182 with Zymomonas
mobilis MTCC 92 increases the production of bioethanol as compared to
monoculture of Klebsiella oxytoca ATCC 13182 and co-culturing of Saccharomyces
cerevisae MTCC 4780. Therefore, this work would help for commercial production
of bioethanol from abundantly found DORB in a cost effective manner. This will
definitely reduce the dependency on foreign countries for fossil fuel.
