β¦ Synopsis
A coculture consisting of two mesophilic anaerobes, produced about 0.8 mole of ethanol per mole of cellulose from a variety of cellulosic materials. The non-cellulolytic member of this coculture, Clostridium saccharolyticum sp. nov. converted glucose and xylose to ethanol and acetic acid in ratios over 4 to 1.

During the growth of Bacteroides cellulosolvens in media containing cellulose, the accumulation of unutilized sugars in the culture broth occurred mainly during the stationary phase of growth. Cells harvested during the stationary phase of growth continued to convert both cellulose and hemicellulose
The reducing sugars, glucose, and ethanol produced during growth of the anaerobes Clostridium thermocellum and Acetivibrio cellulolyticus on cellulose were assayed. Zymomonas mobilTs was grown under similar conditions and could ferment glucose to ethanol. The ethanol production by the cellulolytic
