Abstract

Bioethanol as a biofuel has received significant attention in the recent years. This is expected to provide a solution to the heavy reliance on petroleum based products for energy security, adverse effect on the environment and climate change due to emissions of vehicles. India, being an agriculture-based economy, produces huge quantities of agricultural residues after harvesting the crops. This chapter will, therefore, focus on the availability of agro-residues in India, the assessment of pretreatments, saccharification processes such as acidic and enzymatic methods and fermentation of hydrolysates. The progress achieved in the use of various wild and mutant strains of microbes and recombinants for the production and development of cellulose-hydrolyzing enzyme cocktails and their utility in the saccharification of agro-residues will be discussed. The role of microbial strains in fermenting cellulosic hydrolysates, the need for genetic engineering approach and consolidated bioprocess development for the production of bioethanol will be critically reviewed.

Keywords
