| 摘 要： | 采用絮凝法对味精发酵生产过程中的发酵液中的菌体进行除菌处理，得到了无机凝聚剂与高分子絮凝剂优化复合使用是发酵液去除菌体的有效办法。由不同条件下菌体的絮团形态扫描电镜照片可以看到，无机凝聚剂的加入，可有效地降低菌体的Zeta电位，形成较小的絮团；高分子絮凝剂的加入，由于架桥作用．因而可形成较大的絮团，从而加快沉降速度，提高絮凝效果。

| Abstract: | A research has been done on the separation of bacteria in the fermented liquid from gourmet production by coagulation. The result shows that the combined use of inorganic coagulant and poly-coagulant is efficient in bacteria removal.The Zeta electric potential test and the photos of scanning electronic microscope reveal that the Zeta potential of bacteria has been effectively reduced, resulting in smaller flocculating granules. And bigger granules are formed because of the bridging efforts of the added poly-coagulant,which increases the sedimentation rate and enhances the flocculation effect. |
