Gluconic acid was prepd. in high yield. (over 95% for 50 hrs) Aspergillus niger SE-178 is UV-irradiated to produce its variant Aspergillus niger JSC-1043 (KFCC-10015) which has a high glucose-oxidizing activity and maintains an enzyme actvity in medium contg. more than 40 % of gluose. This strain is incubated in gluconic acid medium and separated aferwards.
