Process for producing glucose isomerase

摘要

A process for producing glucose isomerase which comprises cultivating a glucose isomerase-producing bacterium belonging to the genus Corynebacterium under aerobic conditions in a culture medium containing carbon sources and nitrogen sources and separating the glucose isomerase-containing cells from the culture broth, and a process for producing fructose which comprises contacting glucose in an aqueous medium with the glucose isomerase-containing cells of a bacterium belonging to the genus Corynebacterium or glucose isomerase separated therefrom.
