MUTANT BLOCKED IN GLYCEROL OXIDAION PATHWAY FOR PRODUCING 1,3-PROPANEDIOL

摘要

The present invention relates to a microbial mutant in which the gene encoding transcription activator or the gene encoding dihydroxyacetone kinase in a microorganism having the ability to produce 1,3 -propanediol using glycerol as a carbon source is deleted or inactivated and to a method for producing 1,3- propanediol using the mutant. When the mutant according to the present invention is used, the production of byproducts which are inevitably obtained when producing 1,3 -propanediol from glycerol using prior strains can be minimized, and thus the cost of purification of 1,3-propandiol can be reduced.
