摘要：
The present invention relates to a process for the production of a purified glucose isomerase which comprises contacting an impure extract containing glucose isomerase and soluble impurities with a weakly basic ion exchange material known to adsorb glucose isomerase; adding a first salt solution of a concentration which removes unadsorbed and weakly adsorbed impurities, but not glucose isomerase; and adding a second, buffered salt solution which elutes the adsorbed glucose isomerase.
