Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for objectively and easily evaluating a foul odor, particularly the foot odor of a tinea pedis patient, and to provide a method for evaluating a deodorant effect for a foul odor.SOLUTION: We focused on Corynebacterium striatum which increases significantly in the skin affected area of a tinea pedis patient; tracked down that the fungus generates a foul odor, Corynebacterium striatum is a production fungus of the foot odor of a tinea pedis patient, and further the foul odor generated from Corynebacterium striatum contains isovaleric acid; and found out that it can be used for evaluation of a foul odor. That is, an evaluation method for the foul odor derived from Corynebacterium striatum, an evaluation method for a masking of a foul odor, and a screening method for a foul odor inhibitor are found out. 【課題】本発明は、悪臭、特に足白癬患者の足臭を客観的かつ簡便に評価する方法、及び、悪臭の消臭効果を評価する方法を提供することを課題とする。【解決手段】足白癬患者の皮膚患部において顕著に増加するCorynebacterium striatumに着目し、この菌が悪臭を発生すること、Corynebacterium striatumが足白癬患者の足臭の生成菌であること、さらにはCorynebacterium striatumから発生する悪臭にイソ吉草酸が含まれることを突き止め、悪臭の評価に利用できることを見出した。すなわち、Corynebacterium striatum由来の悪臭の評価方法、悪臭のマスキング評価方法、悪臭抑制剤のスクリーニング方法である。【選択図】 なし
