Enzymatic biosynthesis of ethanol

Paul H. Blum

Research output: Contribution to specialist publicationArticle


A cell-free enzymatic process for synthesizing ethanol from glucose is now available. The process requires multiple regeneration cycles of pyridine nucleotides. This is accomplished by removal of ethanol and adding the glucose and acetaldehyde substrates to the reactor again. Running the process at high temperatures makes it possible to volatilize the ethanol and recover it as it is generated. Continuous removal of the product also favors the process's reactions. In addition to D-glucose, the glucose dehydrogenase can catalyze reactions of other sugars, such as D-idose and D-xylose.
