| Abstract: | Using a strain which be able to endured high concentration L-sorbose selected form the process of two-step VC fermentation, based on the data were on-line measured, and the improved control technology of High Concentration L-sorbose Fed-batch fermentation, we studied the effects of beginning concentration of L-sorbose ? substrate concentration and pH etc. on VC two-step fermentation. A control technology which was used to control fed-batch fermentation process of L-sorbose was obtained, and the level of fermentation and the rates of equipment were also improved. |
