摘　　要：对链霉菌XW5的液体发酵条件进行了单因素研究,通过正交试验设计对该菌株的培养基进行了筛选,同时对发酵代谢进行调节控制。结果表明,该菌株产素的最适发酵条件为:2%淀粉,1.5%黄豆饼粉,0.05%K2HPO40.05%MgSO40.4%CaCO3。NH42SO4对发酵液的效价有较明显的促进作用。The fermenting conditions of streptomyces XW5 was studied, the culture medium and culture condition for streptomyces which produces antibiotic were optimized by orthogonal design.Toptimum fermentation condition includes: 2%starch, 1.5%corn powder, 0.05%K2HPO4, 0.05%MgSO4, 0.4%CaCO3. (NH4)2SO4 has promotion impact to the fermentation .
