The quality of purified 2-KGA from its fermentation products was up to industrial standard. In addition, several hexoses, such as D-glucose and D-sorbitol can be utilized to synthesize 2-KGA by this newly-mixed culture. The growth and anabolism of the B529-V6 were studied in 4M〓 and 300M〓 fermentor respectively. The results showed that its growth and anabolism were affected by carbon sources, ratio of D-glucose and L-sorbose, nitrogen sources, growth factors, inoculum quality and culture condition including the initial pH value, temperature and ventilation.
