Anaerobic fermentation of glycerol by Escherichia coli: A new platform for metabolic engineering
TL;DR: The finding that Escherichia coli can ferment glycerol in a pH-dependent manner should enable the development of an E. coli-based platform for the anaerobic production of reduced chemicals from Glycerol at yields higher than those obtained from common sugars, such as glucose.
