Chemical separation methods for common microbes

Abstract

Abstract To collect microbes from suspensions by a process other than centrifugation, it has been found effective to add inorganic and organic electrolytes in the colloidal state. The addition of electrolytes causes a neutralization of charges on the particles in suspension resulting in their coagulation and precipitation. High‐molecular‐weight compounds which form micelles also promote coagulation and precipitation. It is believed that chemical collection is an extremely efficient method of treatment for the mass production of microbial suspensions.
