【摘要】 通过筛选丙酸钠及红霉素抗性变株的方法 ,获得了一株红霉素高产菌株 F2 -4 ,其发酵水平较出发菌株提高了 15 .2 %。通过对发酵培养基的正交试验及单因素试验使得 F 2 -4菌株的发酵水平有了进一步的提高更多还原

【Abstract】 An Erythromycin productive high-yielding mutant F2 4 was screened by the test of precursor tolerance and Erythromycin tolerance. The fermentation yield of which is 15 2% more than that of parental strain. Furthermore, the Medium Cross-out Test and Single factor Test further improves the fermentation yield of the strain F2 4.更多还原
