英文摘要 | Two metabolically engineered E. coli strains HL2765k and HL27659k, while capable of producing succinate from glucose with high yields, are not able to grow and produce succinate on sucrose. Consequently, the pUR400 plasmid containing scrK, Y, A, B, and R genes was introduced into HL2765k and HL27659k, respectively. Shake flask culture studies showed that the resulting strains can utilize sucrose; the strain HL2765k pUR400 and HL27659k pUR400 can produce succinate aerobically with a molar yield of 0.78 +/- 0.02 mol/mol and 1.35 +/- 0.13 mol/mol, respectively. On introduction of the plasmid pHL413, which encodes the heterologous pyruvate carboxylase (PYC) from Lactococcus lactis, the molar succinate yield increased to 1.60 +/- 0.01 mol of succinate per mole of sucrose by the HL2765k pUR400 pHL413 strain and to 1.84 +/- 0.10 by the HL27659k pUR400 pHL413 strain. In aerobic batch bioreactor studies, the succinate production rate was faster, and succinate production reached 101.83 mM with a yield of 1.90 when dissolved oxygen (DO) was controlled at 40 +/- 7%. In addition, the results showed that DO had an important effect on succinate production by influencing PYC activity. This work demonstrates the possibility of producing succinate aerobically using sucrose as the carbon source. (C) 2011 American Institute of Chemical Engineers Biotechnol.
