Bioethanol produced from renewable biomass has received considerable attention in current years. Ethanol as a gasoline fuel additive as well as transportation fuel helps to alleviate global warming and environmental pollution. This paper reports a preliminary study on the microbial pretreatment (Aspergillus flavus, Phanerochaete chrysosporium NCIM 1197 and co-culture) and fermentation of the areca nut husk. A combination of different fungi obtained from screening was used for pretreatment and, yeasts and bacterium Zymomonas mobilis NCIM 2915 was used for carrying out fermentation. Zymomonas mobilis NCIM 2915 was showed maximum ethanol production after fermentation from areca nut husk as followed by Pichia stipitis NCIM 3498, Saccharomyces cerevisiae NCIM 3095 and Candida shehatae NCIM 3500. Hence, fungal pretreatment by cellulolytic fungi was more effective for ethanol production. Areca nut husk was revealed as a suitable substrate for ethanol production.
