使用生物氮素替代林可霉素发酵培养基中黄豆饼粉。摇瓶结果显示，不同的替代比例对林可霉素发酵的影响大不相同。合适的替代比例可以改善发酵中后期的菌丝形态，大幅提高发酵水平。在50L发酵罐，使用生物氮素替代40％的黄豆饼粉，可以提高发酵效价9．79％。生物氮素质量稳定，且有一定的相对价格优势，在林可霉素发酵生产上有着不错的应用前景。

we use biological N to be replacement of soyabean cake powder in Lincomycin fermentation medium. Shake-flask culture results show that different replacement ration in lincomycin fermentation have different effect. A suitable replacement ratio can ameliorate the mycelial morphology during fermentation, greatly improve the fermentation level. In 50 L f~rmentor, biological N replace 40% soybean cake powder, can improve fermentation titer 9.79%. Due to Biological N＇s stable quality reasonable price, it will be a good application prospect in the lincomycin fermentation production.
