industrial materials [4]. An increase in importance of bioethanol is not only due to depletion of the oil reserves but also the negative impact of fossil fuels on the environment such as high greenhouse gas emis- sions. With an increasing oil prices and global environmental concerns, bioethanol production has become a focus of great attention [5]. Currently, bioethanol is produced from starch based materials (e.g. wheat, corn, barley) or sucrose containing feed stocks (e.g. sugar cane). However, the production of bioethanol from food crops has triggered ‘food verses fuel’ debate. To overcome these limitations, lig- nocellulosic biomass such as switchgrass [6], cornstover [7], rice straw [8], wheat straw [9] and various agricultural and forest residues could be used for bioethanol production. Pretreatments such as ther- mochemical steam explosion followed by the enzymatic hydrolysis of the material are needed to breakdown the complex lignocellulosic materials into fermentable sugars [10]. Thermochemical pretreatment breaks up the recalcitrant structure of lignocelluloses making the polysaccharide amenable to enzymes [11]. However, it is essential to reduce production cost in all possible steps throughout the process of conversion of various biomasses and wastes to bioethanol. Thus, our objective of this work was to develop a cost effective continuous process to increase the productivity of lignocellulosic ethanol.
