オビスギ材の水蒸気乾燥排気から回収した精油の防カビ性能評価

抄録

"Antifungal activity of the essential oil and the exhaust-steam condensate which were obtained by steam drying of Obisugi wood was evaluated against six kinds of filamentous fungus. Two %(v/v) of the essential oil in plate media strongly inhibited the mycelial growth of Botrytis spp., appreciably that of Fusarium spp., and slightly that of Trichoderma spp.. Fifty %(v/v) the exhaust-steam condensate in the media inhibited Botrytis spp. growth to some extent. The addition of ethyl alcohol at 2%(v/v) into the media containing the essential oil or the exhaust-steam condensate increased the inhibition activity against Botrytis spp., while the alcohol addition into agar media without the oil or the condensate showed no inhibition. The essential oil and the exhaust-steam condensate from Obisugi wood can be used as a natural fungicide against Botrytis spp.."
