  • 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.

  • Patent number: 8951763
    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.

  • Publication number: 20090214454
    Abstract: The present invention relates to a method for inhibiting melanin generation or a method for skin whitening using an active fraction of Erigeron breviscapus extract or matricaria acid methyl ester isolated from the same. The active fraction obtained by solvent fractionation from Erigeron breviscapus whole plant extract and (2Z,8Z)-matricaria acid methyl ester isolated from the fraction inhibit melanin generation in melanocytes without cytotoxicity, so that they can be effectively used for skin whitening.
