Abstract
This invention relates to a process for the production of a purified glucose isomerase enzyme which comprises contacting an enzyme extract containing glucose isomerase and impurities with a first polysulfone membrane not normally permeable to glucose isomerase, in the presence of a salt concentration capable of selectively inducing permeation of glucose isomerase through the membrane, and obtaining a glucose isomerase containing permeate.
