Continuous Cellulosic Bioethanol Fermentation by Cyclic Fed-Batch Cocultivation [PDF]

Applied and Environmental Microbiology, 2013
ABSTRACT Cocultivation of cellulolytic and saccharolytic microbial populations is a promising strategy to improve bioethanol production from the fermentation of recalcitrant cellulosic materials. Earlier studies have demonstrated the effectiveness of cocultivation in enhancing ethanolic fermentation of cellulose in batch ...
