Production of bioethanol by facultative anaerobic bacteria

Abstract

There is increased interest in using facultative aerobic bacteria to produce bioethanol from waste materials, including complex hemicellulosic biomass. In this laboratory study, ethanol was produced by different facultative aerobic bacteria (Lactobacillus plantarum M24, Lactobacillus sakei LB49, Weissella viridescens LB37 and Pediococcus acidilactici M17) from diverse waste materials (corn, corncob, paper and pine cones). Of these, corn was found to be the best substrate for bioethanol production with L. plantarum M24 the most efficient bacterium for most of the selected waste materials.
