Abstract | To obtain high-yield production of 2,3-butanediol (2,3-BD) from glucose, we optimized the culture conditions for a lactate dehydrogenase-deficient mutant (ΔldhA) of Klebsiella pneumoniae using response surface methodology. 2,3-BD production was successfully improved by optimizing pH (5.6), aeration (3.50 vvm) and concentration of corn steep liquor (45.0 mL/L) as a nitrogen source, resulting in a maximum level of 2,3-BD production of 148.8 g/L and productivity of 2.48 g/L/h. 2,3-BD was also obtained with high concentration (76.24 g/L) and productivity (2.31 g/L/h) from the K. pneumoniae mutant strain using sugarcane molasses as a carbon source. |
