Overview Ethanol Production from Lignocellulosic Materials

Abstract

Ethanol from lignocellulosic materials attracts interest to fulfill the global demand on decreasing net emission of C02, as well as an oxygenate additive to gasoline by sustairtable processes. The polymer sugars within lig~ocelluloses are decomposed to their monomers by either dilute-acid or enzymatic hydrolysis. The lignocellulosic hydrolyzate is then fermented to ethanol using Saccharomyces cerevisiae or other fermenting microorganisms. This lignocellulose-to-ethanol process is still considered as newly emerging technology but many scientific papers have been published on various aspects of it. The progress on this conversion technology is briefly reviewed here.
