Abstract


Microflora of EM1 culture is converted from aerobic and neutral to anaerobic and acidic. Biochemical characteristics of EM1 changed according to change of microflora. pH, EC and content of organic acid of EM1 at the end of culture were 3 - 3.5, 0.6 - 0.9 s/m and 1.9 - 2.1 %, respectively. Antioxidation activity of EM1 increased in proportion to log-phase of effective microorganisms. Antioxidation activity of EM1 depended more upon antioxidation activity of organic acid than SOD activity. EM2 and EM3 had high antioxidation activity and EM2 had antibiotic action.
