Production of functionalized polyhydroxyalkanoates by genetically modified Methylobacterium extorquens strains
BACKGROUND Methylotrophic (methanol-utilizing) bacteria offer great potential as cell factories in the production of numerous products from biomass-derived methanol. Bio-methanol is essentially a non-food substrate, an advantage over sugar-utilizing cell factories. Low-value products as well as fine chemicals and advanced materials are envisageable from methanol. For example, several methylotro...
متن کاملdehydrogenase from Methylobacterium extorquens
The structure of methanol dehydrogenase (MDH) at 0.194 nm (1.94 A) has been used to provide a model structure for part of a membrane quinoprotein glucose dehydrogenase (GDH). The basic superbarrel structure is retained, along with the tryptophandocking motifs. The active-site regions are similar, but there are important differences, the most important being that GDH lacks the novel disulphide r...
متن کاملMetabolic engineering of Methylobacterium extorquens AM1 for 1-butanol production
BACKGROUND Butanol is a promising next generation fuel and a bulk chemical precursor. Although clostridia are the primary industrial microbes for the fermentative production of 1-butanol, alternative engineered hosts have the potential to generate 1-butanol from alternative carbon feedstocks via synthetic metabolic pathways. Methylobacterium extorquens AM1, a facultative methylotrophic α-proteo...
متن کاملMedia Selection for Poly(hydroxybutyrate) Production from Methanol by Methylobacterium Extorquens DSMZ 1340
Plackett-Burman design was used for selection of important media components such as carbon and nitrogen sources and minerals which affect poly(hydroxybutyrate) production and cell growth of Methylobacterium extorquens DSMZ 1340. Among the studied variables, nitrogen and phosphorus sources, MgSO4 and most of the trace elements were found to be significant variables for PHB product...
متن کاملCo-Consumption of Methanol and Succinate by Methylobacterium extorquens AM1
Methylobacterium extorquens AM1 is a facultative methylotrophic Alphaproteobacterium and has been subject to intense study under pure methylotrophic as well as pure heterotrophic growth conditions in the past. Here, we investigated the metabolism of M. extorquens AM1 under mixed substrate conditions, i.e., in the presence of methanol plus succinate. We found that both substrates were co-consume...
