ABSTRACT:
A mutant Streptomyces thermoviolaceus, NRRL 15615, elaborates a thermostable glucose isomerase in high yield, constitutively. The GI produced shows a negligible loss in activity when heated at 90.degree. C. in high fructose corn syrup for 5 minutes relative to the same treatment at 80.degree. C. The mutant microorganism produces about 1500 units of glucose isomerase per gram of dry weight cells in the absence of xylose.
