STUDIES ON THE BREEDING AND FERMENTATION CONDITIONS OF KOJIC ACID PRODUCING STRAIN
曲酸菌选育及发酵工艺研究

ASP. oryzae MSA was screened from 12 strains. Two mutants Chllh and AC6 with higher ablity of production of kojic acid were obtained by UV and 60Co ray. Fermentation technology was studied, the result showed that the two stains can produce kojic acid over 5% after five days. Fermentation broth was concentrated directly, decolorized and recryshtized, and the product of prismatic needles were obtained.
