PROBLEM TO BE SOLVED: To provide an aerosol device for mildew-proofing capable of storing mildew-proofing microorganisms in an effective state for a long period of time, easily depositing the mildew-proofing microorganisms on the whole of an object for a mildew-proofing treatment uniformly as much as possible to easily obtain a high mildew-proofing effect, and securing safeness of a human body in a mildew-proofing treatment.SOLUTION: The mildew-proofing aerosol device 1 contains: mildew-proofing microorganisms that form spores under prescribed conditions and proliferously grow on a surface of an object for a mildew-proofing treatment to suppress proliferous growth of other fungi a liquid in which the mildew-proofing microorganisms are mixed an aerosol container 2 housing the mildew-proofing microorganisms and the liquid and an inert compressed gas with low chemical reactivity, which fills the aerosol container 2.COPYRIGHT: (C)2012,JPO&INPIT【課題】防カビ微生物を長期間に亘って有効な状態で保存できるようにし、しかも、防カビ微生物を、防カビ対象物の全体にできるだけムラ無く、かつ、手軽に付着させて高い防カビ効果を容易に得ることができ、さらに、防カビ処理時における人体への安全性も確保する。【解決手段】防カビ用エアゾール装置1は、所定条件下で芽胞を形づくり、防カビ対象物の表面で増殖して他の菌の増殖を抑制する防カビ微生物と、防カビ微生物が混合される液体と、防カビ微生物及び液体を収容するエアゾール容器2と、エアゾール容器2内に充填された化学反応性の低い不活性な圧縮ガスとを含んでいる。【選択図】図1
