Abstract
A microorganism Bacillus sp. NRRL B-5350 or its mutant B-5351 is cultured under aerobic conditions in a nutrient medium contg. an N- and C-source, small amts. of inorganic salts, vitamins and pref. xylose, at a pH of 6-8 and at 35-65 degrees C and the glucose-isomerase is then isolated by filtration or centrifugation of the cells, treatment with cobalt salt followed by heating to destroy the lytic enzyme systems.
