Abstract

Sweet sorghum is one of the most attractive feedstocks for producing liquid fuels in the world since it is well adapted to the various land conditions and efficiently converts CO2 into sugars. Sweet sorghum was evaluated as a raw substrate for production of ethanol from the whole plant. It consists of 37% juice, 8% seed head, 36% bagasse, and 19% leaf matter which can produce ethanol via fermentation of Saccharomyces cerevisiae. Especially, starch in seeds was hydrolyzed to simple sugars by amylase. Bagasse and leaf matter were treated with calcium hydroxide at 121°C for 1 h at 15 psi before hydrolysis by cellulase. In this study, 1 ton of whole sweet sorghum contains 283 kg solid matter and 229. 8 kg carbohydrates and produces 59 kg ethanol. © 2012 The Korean Society of Food Science and Technology and Springer Netherlands.
