Abstract
The present invention relates to a method for producing 3-hydroxypropionic acid by culturing in a glycerol-containing medium a mutant microorganism obtained by inserting or amplifying a gene encoding propanediol utilization protein in a microorganism having the abilities to produce coenzyme B12 and produce 3-hydroxypropionic acid using glycerol as a carbon source. According to the present invention, 3-hydroxypropionic acid can be produced in high yield from glycerol without having to add expensive coenzyme B12 as a cofactor.
