Fermentation process using enzymatic strain enhances the bio fuel Production from lignocellulosic biomass

Bio ethanol is an attractive, sustainable energy source to fuel transportation, produced from kinds of biomasses. Among kinds of biomass, lignocellulosic biomass is a very useful feedstock to economically produce environmentally friendly biofuels. The main goal of the research described in this paper is to investigate the process of pretreated biomass, acid or enzymatic hydrolysis, Fermentation and Ethanol separation/ purification. Ethanol can be produced from many feedstock’s, including cereal crops, corn (maize), sugar cane, rape straw, wheat straw, corncob etc. Technologies for the production of alternative fuels are receiving increased attention owing to concerns over the rising cost of petrol and global warming. Hexoses are the Primary carbohydrate, which can easily fermented by yeast but yeast has ability to ferment only hexoses but not Pentoses. Xylose is the second most abundant carbohydrate in the lignocellulosic biomass hydrolysate. The fermentation of xylose is essential for the bioconversions of lignocelluloses to fuels. For the complete fermentation of carbohydrates genetically engineered yeast strain is a better way, which enhances the production of ethanol. For the better result improvement in fermentation process, use of yeast strain is an acceptable necessary action. The development of novel yeast strains with increased tolerance toward inhibitors in lignocellulosic hydrolysates is highly desirable for the production of bio-ethanol. This yeast displayed improved tolerance to xylose and ethanol production. The use of bioethanol as a motor fuel has as long a history as the car itself.
