Abstract: The fermentation conditions of Burkholderia cepacia NTG-15-03 for the production of lactobionic acid were optimized using one-factor-at-a-time method and response surface analysis based on quadratic regression orthogonal design. The optimal fermentation conditions for the production of lactobionic acid were fermentation pH of 7.0, seed age of 24 h, inoculation amount of 2% and fermentation time of 106 h. Under these conditions, the yield of lactobionic acid was up to 10.08 g/L.

Key words: lactobionic acid, response surface analysis, fermentation
