論文の詳細を見る
Antimicrobial activity of Monascus pilosus IFO 4520 was examined to prevent contamination during beni-koji making in the open air. The antibacterial effect of the benikoji prepared with this strain occurred with 30mg/ml of beni-koji extract in combination with 0.5% lactic acid against two contaminants of koji, Micrococcus varians and Bacillus subtilis. There were two compounds, antibacterial and antiyeast substances, in the beni-koji extract. These results suggest a possibility of inhibiting the growths of contaminants during beni-koji making using beni-koji extract and lactic acid.
