GAO Hua, TANG Fang, TAN Tianwei. COMPARISON AND ANALYSIS OF DIFFERENT FED - BATCH METHODS ON FERMENTATION OF ERGOSTEROL[J]. CIESC Journal, 2002, (12).DOI:
The effects of different fed-batch methods on the biomass and ergosterol content in Saccharomyces cerevisiae were studied. The relationships of such parameters as pH
DO and concentration of glucose with biomass and ergoterol content were discussed under the circumstances of constant feed rate fed - batch
constant glucose - concentration fed - batch
exponential fed - batch
DO - control exponential fed - batch
pulse fed -batch
DO-control pulse fed-batch. Explanations and analysis of these phenomena were provided. According to the results of experiments
DO -control pulse fed- batch is an effective method for the fermentation of ergoterol. Compared with the traditional method
the actual yield (the product of biomass and ergoterol content) could be improved by 20% .
