MUTANT MICROORGANISM HAVING HIGH ETHANOL GENERATION ABILITY FROM GLYCEROL OR CRUDE GLYCEROL, AND METHOD FOR PRODUCING ETHANOL USING SAME

摘要

The present invention relates to a mutant microorganism having enhanced capacity for generating ethanol using glycerol or crude glycerol as a carbon source, and to a method for producing ethanol using same. More particularly, the present invention relates to a mutant microorganism having high ethanol generation ability from glycerol or crude glycerol, wherein the enzymatic activity of alcohol dehydrogenase (AdhII) is increased and the enzymatic activity of 1,3-propanediol oxidoreductase (DhaT) is decreased in the mutant organism. The present invention also relates to a microorganism improved by means of the aforementioned mutation, and to a method for producing ethanol using the mutant microorganism.
