  • Method of producing 3-hydroxypropionic acid from glycerol
    Patent number: 9090919
    Abstract: The present invention relates to a novel method of producing 3-hydroxypropionic acid from glycerol, and more particularly to a method of producing 3-hydroxypropionic acid by culturing in a glycerol-containing medium a mutant microorganism obtained by amplifying an aldehyde dehydrogenase-encoding gene in a microorganism having the abilities to produce coenzyme B12 and produce 3-hydroxypropionic acid using glycerol as a carbon source. The present invention enables the fermentation of glycerol even under microaerobic or aerobic conditions without having to add coenzyme B12. Thus, the invention will be very suitable for the development of biological processes for producing large amounts of 3-hydroxypropionic acid.

  • Method of producing 1,3-propanediol using recombinant strain in which glycerol oxidative pathway has been blocked
    Patent number: 8338148
    Abstract: Provided is a method of producing 1,3-propanediol by culturing a recombinant strain in which the glycerol oxidative pathway had been blocked, and more particularly a method of producing 1,3-propanediol by two-step culture of a recombinant strain in which the oxidative pathway that produces byproducts in the glycerol metabolic pathway had been blocked. When the recombinant strain in which the glycerol oxidative pathway that produces byproducts had been blocked is cultured in two steps, 1,3-propanediol can be produced with improved yield without producing products that result in an increase in purification costs.
