ABSTRACT

 

Pretreated deseeded sunflower head as lignocellulosic biomass can be utilized to produce ethanol, a promising alternative energy source for the depleting crude oil. Present study is to evaluate the efficiency of microbial fermentation process in production of ethanol from lignocellulosic biomass. There are two steps involved in such fermentation- hydrolysis of cellulose in the lignocellulosic biomass to reducing sugars and fermentation of the sugars to ethanol. The microbial used for the study are Zymomonas mobilis 89, Saccharomyces cerevisiae 180, Saccharomyces cerevisiae 181, Heterobasidion annosum 146, and Cellulomonas fimi 24.

 

Keywords : Zymomonas mobilis, Deseeded sunflower head, Ethanol, Fermentation, Lignin
