Bioethanol obtained from lignocellulosic biomass is the most promising biofuel resource to tackle problems like rapid depletion, rising global warming and crude oil prices related to the energy derived from conventional resources. There are three main processes required in the bioethanol production from agricultural lignocellulosic wastes viz. pretreatment, hydrolysis, and fermentation. Hydrolysis can be carried out either biologically (enzymatic) or chemically (acidic). The main factor limiting the bioethanol commercialization is in the development of the step called enzymatic hydrolysis. Challenges like high enzyme cost, phenolic compounds affecting the activity of enzymes and thermal inactivation of cellulase and hemicellulase enzymes make enzymatic saccharification a bottleneck of the overall bioethanol production. This paper reviews the steps involved in bioethanol production from lignocellulosics with emphasis on recent trends of enzymatic hydrolysis process for cost-effective bioethanol production.
