Studies on feeding condition of guanosine fermentation .

鸟嘌呤核苷补料发酵条件研究。

Effects of hypoxanthine feeding on guanosine fermentation such as cell concentration , ph , residual sugar and guanosine yield were studied on the basis of the exploration of the best hypoxanthine feeding way .

在探索次黄嘌呤最佳流加方式的基础上，系统研究了后期流加次黄嘌呤对发酵液菌体浓度、ph值、残糖含量以及鸟苷产量的影响。
