ANTIOXIDANT AND EVALUATION OF MICROORGANISM HAVING ANTIOXIDANT ACTIVITY

摘要

PROBLEM TO BE SOLVED: To establish a method capable of simply searching microorganisms having anti-oxidant action and obtain an excellent antioxidant by the method. ;SOLUTION: Anti-oxidant action which microorganisms have is evaluated by inoculating a microorganism to be evaluated into each of a culture medium to which rose bengal is added and a culture medium to which rose bengal is not added, culturing the microorganism under light irradiation, determining bacterial numbers or turbidity and obtaining a ratio of measured value of each culture medium. The anti-oxidant comprises a yeast, e.g. Candida stellatus, Candida parapsilosis, Rhodotorula rubra, Hyphopichia burtoni or Saccharomyces unisporus selected by the above evaluation method or its cultured product.;COPYRIGHT: (C)1998,JPO
