제목 Co-production of 3-hydroxypropionic acid and 1,3-propandiol by recombinant  Klebsiella pneumoniae
초록 3-hydroxypropionic acid (3-HP) production from glycerol has gained much attention due to the importance of 3-HP as platform chemical. 3-HP production is composed of two reactions i.e. conversion of glycerol to 3-HPA oxidation to 3-HP. Klebsiella pneumoniae, one of the candidates for 3-HP production, has advantage of natural synthesis of B12 under anaerobic condition. However, further reaction of 3-HPA to 3-HP involves the reduction of NAD+ and consequently NAD+ regeneration is very important for efficient production of 3-HP. On the other hand, production of 1,3-PDO by NADH-dependent oxidoredcutase of K. pneumoniae has been studied extensively. Hence, in this study, we tried co-production of 3-HP and 1,3-PDO using K. pneumoniae mutants and studied the effect of various environmental factors and genetic backgrounds on co-production yields change in K. pneumoniae.
