Cellulosic ethanol would reduce our petroleum dependency, as ethanol is produced from the inexpensive and plentiful feed stocks.

The ethanol fermenting genes such as pyruvate decarboxylase (pdc) and alcohol dehydrogenase II (adh II) were cloned from Zymomonas mobilis and transformed into three different cellulolytic bacteria, namely Enterobacter cloacae JV, Proteus mirabilis JV and Erwinia chrysanthemi and their cellulosic ethanol production capability was studied. cloacae JV was found to produce 4.5% and 3.5% (v/v) ethanol, respectively, when CMC and 4% Na OH pretreated bagasse were used as substrates, whereas recombinant P. chrysanthemi with the same substrates could only produce 4%, 3.5%, 1%, and 1.5 % of ethanol, respectively. cloacae strain produced twofold hher percentage of ethanol than the wild type. cloacae strain could be improved further by increasing its ethanol tolerance capability through media optimization and also by combining multene cellulase expression for enhancing ethanol production from various types of lnocellulosic biomass so that it can be used for industrial level ethanol production.
