As a result , the colloidal particles flocculate as large, less dense aggregates are more easily filtered.
胶粒过大, 就发生絮凝,低密度聚合的胶粒,容易过滤.
Their culture broths possessed the ability to flocculate kaolin suspension in the presence of 1% CaCl_2, which was identified to be a Bacillus brevis based on its morphological and physiological characteristics and the partial 16S rRNA sequencing method.
在1%CaCl2存在下,其发酵液对高岭土悬液具有较高的絮凝活性。根据形态及生理生化特征,利用16S RRNA部分序列分析确定该菌归属于Bacillus brevis。
