Cotton wastes comprise lignin, hemicelluloses and cellulose, which can be utilized as sustainable for the production of bioethanol. Cotton based lignocellulosic biomass requires specific pretreatment strategy to efficiently remove lignin and to solubilize hemicelluloses, which increases the accessibility of hydrolytic enzymes during saccharification. Waste paper, a major source of cellulosic biomass, could be utilized as a potential substrate for cellulase production. Different pretreated waste papers were used as substrates for cellulase production. Trichoderma spp. is used for Bioethanol production because of high metabolic activity in production of cellulase enzyme and hydrolysis of cellulose to glucose. Bioethanol has been identified as the mostly used biofuel worldwide since it significantly contributes to the reduction of crude oil consumption and environmental pollutions. Compared to other types of microorganisms, yeasts especially saccharomyces cerevisiae is the common microbes employed in ethanol production due to its high ethanol productivity, high ethanol tolerance and ability of fermenting wide range of sugar. The production of bio-ethanol by microbial saccharification and fermentation process. The common process involves in ethanol production are pretreatment, hydrolysis and fermentation. Productions of bio-ethanol during fermentation depend on several factors such as temperature, pH, inoculum size, and sugar concentration.
