Description
前記硫化水素産生菌を所定時間培養後に、前記サンプルの直下における嫌気性条件下での前記硫化水素産生菌の硫化水素の産生を指標として、前記サンプルの前記硫化水素産生菌に対する抗菌性を検査する抗菌性検査方法を提供する。
本発明に係る抗菌性検査方法で抗菌性を検査することが可能なサンプルとしては、非通気性のサンプルが挙げられる。
本発明に係る抗菌性検査方法では、サルモネラ菌及び/又はシトロバクター菌などの硫化水素産生菌に対する抗菌性を検査することができる。
本発明に係る抗菌性検査方法で抗菌性を検査することが可能なサンプルは特に限定されず、本発明では、固体状のサンプル、液体状のサンプルなど、様々な状態のサンプルの抗菌性を検査することができる。また、前述のとおり、本発明に係る抗菌性検査方法では、水溶性物質のみならず非水溶性物質の抗菌性をも検査することが可能である。
本発明に係る抗菌性検査方法において用いることができる培地は特に限定されず、公地の固体培地を自由に選択して用いることができる。また、用いることができる栄養源なども特に限定されず、培養する菌の性質などに応じて、自由に選択して用いることができる。例えば、グルコース、フルクトース、ショ糖、乳糖、澱粉、グリセリン、デキストリン、レシチン、などの炭素源:硫酸アンモニウム、硝酸アンモニウム、リン酸‐アンモニウム、リン酸二アンモニウム、塩化アンモニウムなどの無機窒素源:アミノ酸、ペプトンなどの有機窒素源、ナトリウム、マグネシウム、カリウム、鉄、亜鉛、カルシウム、マンガンなどの無機栄養源、その他ビタミンなどから1種または2種以上の栄養源を自由に選択して用いることができる。
本発明に係る抗菌性検査方法において行う培養の培養条件も特に限定されず、培養する菌の性質などに応じて、培養温度、pH、培養時間など、自由に設定することができる。
本発明に係る抗菌性検査方法で対象となる菌も、嫌気性条件下での増殖が可能な菌であれば特に限定されず、あらゆる菌を対象とすることができる。例えば、前述のように、硫黄源や鉄源を含有する培地を用いる場合には、本発明に係る抗菌性検査方法を用いて、サルモネラ属菌、シトロバクター属菌、プロテウス属菌、エドワージエラ属菌などの硫化水素産生菌に対する抗菌性を検査することができる。
本発明に係る抗菌性検査方法では、サンプル直下における菌の増殖状態を検出する。本発明において、菌の増殖様態の具体的な検出方法は特に限定されないが、例えば、サンプル直下の培地の色調変化を解析することで、菌の増殖状態を検出することが可能である。
Claims (3)
- 対象の硫化水素産生菌が接種された、硫黄源と鉄源とを含有する培地上にサンプルを留置し、
前記硫化水素産生菌を所定時間培養後に、前記サンプルの直下における嫌気性条件下での前記硫化水素産生菌の硫化水素の産生を指標として、前記サンプルの前記硫化水素産生菌に対する抗菌性を検査する抗菌性検査方法。 - 前記サンプルは、非通気性である請求項1記載の抗菌性検査方法。
- 前記硫化水素産生菌は、サルモネラ菌及び/又はシトロバクター菌である請求項1または2に記載の抗菌性検査方法。
