研究了在赤霉素GA4＋7生物发酵过程中，流加补氨水代替碳酸钙精确调控发酵pH对发酵与提炼的影响，结果表明流加补氨水代替碳酸钙工艺可应用于赤霉素GA4＋7发酵生产中，对赤霉素GA4＋7发酵具有促进作用。其能提高发酵水平6％以上，同时因消除了钙离子对膜分离的影响，可提高后提取工艺收率4％以上。

Effects of replacing calcium carbonate with ammonium feeding in gibberellins GA4＋7 fermentation and recovered rate were studied. The research showed that the continuous ammonium feeding technique could be utilized in gibberellins GA4＋7 fermentation and production, and could positively enhance the production of gibberellins GA4＋7. The yield/titer was 6% higher than control and recovered rate was 4% higher because the negative effect of calcium on nltrafiltration membrane （NF） and nanofiltration membrane （NF） was eliminated.
