本発明の抗カビ剤組成物を対象物(衣料、カーテン、カーペット、ソファ、タイル、壁、壁紙、床、床下、畳)(対象表面)に接触させることで優れた防カビ、抗カビ効果が発現するが、接触後、当該対象物を乾燥させることが好ましい。本発明の抗カビ剤組成物を対象表面に接触させる方法は限定されないが、例えば、抗カビ剤組成物を対象物にスプレー等で噴霧する方法、抗カビ剤組成物を対象物に塗布する方法、抗カビ剤組成物を含む処理浴に対象物を浸漬する方法等が挙げられ、いずれの方法も、接触後に当該物を乾燥することが好ましい。本発明は、所定の抗カビ剤組成物を用いたカビ繁殖防止方法に関するものである。
1)カビ懸濁液
ポテトデキストロース寒天培地に生育させたAspergillus.niger胞子と菌糸を、滅菌した0.05%Tween(レオドールTW-0120)水溶液に分散させ、600nmにおける吸光度を0.1に合わせた液を調製した。
滅菌処理(オートクレーブ:2atm(202650Pa)、125℃/15min)をした綿メリヤス布(1.5cm×1.5cm)に、滅菌処理した2.4%ポテトデキストロース水溶液を200μl、上記カビ懸濁液を100μl、下記配合の抗カビ剤組成物を200μl塗布する(オートピペッターを用い定量しながら所定の布にできる限り広範囲に広がるように滴下した)ことでカビ試験布とした。次に、この試験布をシャーレ上に置き、ユニットデシケーター(アズワン)内で25℃、100%RHで4日間保存し、保存後に生育しているカビの菌糸、胞子の様子を視覚判定した。尚、抗カビ剤組成物の調製に際し用いた生理食塩水は10%塩酸を用いてpH7.7とした。
視覚判定値は表1に示すようにカビの生育状態を0〜4の5段階に設定し数値化した。評価点0点及び1点は、カビの生育が抑えられ、抗カビ性効果が顕著に認識できる。結果を表2に示す。
