Bioethanol is a liquid biofuel produced from lignocellulosic biomass. Seven number of lignocellulosic biomass were selected for the biomass characterization such as arecanut shell, arecanut sheath, corn cob, cotton stalk, maize shank, paddy husk and pearl millet stalks. From the physicochemical analysis three biomass (pearl millet stalks, arecanut husk, cotton stalk) were selected for further study. In this study, a pilot scale system of 50 l capacity was designed and developed for fermentation with working volume of 33.33 l. The bioethanol yield, bioethanol concentration, bioethanol production rate was found as 0.023 g g-1, 23.12 g l-1 and 0.24 g l-1h-1 respectively after 96 h of fermentation. The practical yield, theoretical yield and the fermentation efficiency were 6.26, 11.74 g l-1 and 53.30 % respectively at 24 h which increased to 23.12, 27.29 g l-1 and 84.69 % respectively after 96 h of fermentation
