Production of gamma-butyrolactone by the acid-treatment of 4-hydroxybutyric acid containing fermentation broth |
초록 |
γ-Butyrolactone (GBL) is an industrially important four carbon chemical. GBL can be produced by acid treatment of 4-hydroxybutyric acid (4-HB), a derivative of succinic acid. Metabolic pathways were established in succinic acid overproducing M. succiniciproducens LPK7 by introducing succinyl-CoA synthetase, CoA-dependent succinate semialdehyde dehydrogenase, and either 4-hydroxybutyrate dehydrogenase in LPK7 (p3S4CD) or succinate semialdehyde reductase in LPK7 (p3SYCD). Fed-batch cultures of LPK7 (p3S4CD) and LPK7 (p3SYCD) resulted in the production of 6.37 and 6.34 g/L of 4-HB, respectively. Finally, GBL was produced by acid treatment of the 4-HB obtained from the fermentation broth.
