PROCESS FOR OBTAINING GLUCOSE ISOMERASE FROM STREPTOMYCES STRAIN

摘要

Process for obtaining glucose isomerase from a strain of Streptomyces BR/ The strain of Streptomyces sp. No. 765, filed under number 143 at the State Institute for Drugs Control, for 36 to 72 hours in culture medium using xylose as an indicator, the temperature is maintained between 24 to 36 degrees C, the initial culture pH is From 6.5 to 9.0, the isomerization temperature is from 50 to 90 degrees C, the pH is from 6.0 to 9.0, and the reaction is carried out in the presence of MgSO4, 7H2O at a concentration of 1.10. 4 to 1.10 ** - 2 M and a substrate concentration of 0.1 to 3 M. BR/ Transformation of D-glucose into D-fructose.
