最近有很多同志写信讯问我们办小型细菌肥料厂时液体培养的情况,由于工作很忙,未能一一答复,因此利用生物学通报给我们的机会,将我们组织生产的点滴心得体会简单地介绍一下供读者参考。一、液体深层培养在配制微生物培养基时,除所需的养料物质外,通常都加些凝固剂(如洋菜),凝固剂冷却后呈膠冻状,因此习惯上將这样的培养基称为固体培养基。与固体培养基相反,液体培养基不加凝固剂(如洋菜),而其他成分则往往完全相同。应用液体培养基时,又分成为表
Recently, many comrades wrote to us about the situation of liquid culture in our small-scale bacterial fertilizer factory. Due to the busy schedule of work, we have not been able to answer these questions one by one. Therefore, taking advantage of the opportunity presented by biology to give us some insight into the production of our organization, Introduction for readers reference. First, the liquid deep culture In the preparation of microbial culture medium, in addition to the required nutrients, usually add some coagulant (such as agar), coagulation cooling was jelly-like, so customary to such a medium Solid medium. In contrast to solid medium, liquid medium is not coagulant (such as agar), while other components are often identical. When using liquid medium, it is divided into tables
