| Abstract: | A new technology, extractive fermentation using ion exchange resin, for fermentation of L malic acid was developed in this research. The best fermentative conditions were determined finally. Among them, initial point for batch fermentation converting to extractive fermentation was 36h, dilution rate was 0.15h -1 , extractive fermentation period was 96h. Compared with conventional batch fermentation, this novel method increased both glucose conversion rate and L malic acid production rate evidently, decreased the fermentation period conspicuously. |
