Abstract
Antifoaming agents are commonly used during culturing of enzyme-producing microorganisms. These antifoams often persist through enzyme processing, slowing filtrations, clogging filtration membranes and adversely affecting the quality of the final product. The present invention describes a method for removing antifoams, and often carbohydrates and pigments, from enzyme systems using mineral clay, the preferred clay being bentonite.
