生物氮素在阿维菌素发酵中的应用研究

Application Study of Bionitrogen in Avermectins Fermentation

生物氮素是近几年才开始应用于阿维菌素发酵生产的一种新型氮源物质,可以在发酵培养基中部分或全部替代传统的氮源物质,如黄豆饼粉、酵母粉等。通过进行摇瓶实验,寻找合适的生物氮素添加比例。结果显示,生物氮素替代60%的黄豆饼粉时效果最好,摇瓶效价提高8.5%。

Bionitrogen is a new kind of nitrogen source material.It is applied in the avermectins fermentation in the last few years.It can be replaced part or all traditional nitrogen source material,for example,soybean flour,leaven powder,soybean meal and peanut cake powder...etc.By carring on shaking bottle experiment,this paper looked for a suitable bionitrogen to add a comparison,the results showed that bionitrogen replaced 60% soybean flour was best,the effect price of shaking bottle raised 8.5%.
