Apart from these feed stocks, lignocellulosic biomass which comprise mostly of cellulose (20–50%), hemicellulose (20–35%), and polyphenolica lignin (10–35%) [5,6,8], is an alternative feed stock for bioethanol production. The lignocelluloses are by far, the earth’s most prevalent renewable organic materials available for microbial or other conversions. This biomass including forest residues such as wood; agricultural residues such as sugarcane bagasse, corn cob, corn stover, wheat and rice straw, has received widespread interest due to their availability, abundance
and relatively low cost [9].
