Genetical and physiological studies of photocatalytic disinfection of Escherichia coli.
水資源缺乏引起的一系列問題在世界上已建得到廣泛關注,因此,確保提供潔淨衛生的水在保護人類健康和環境方面起著重要作用。近來,光催化作為頗有前景的替代方法被廣泛應用殺菌除污。二氧化鈦是目前研究最多應用最廣的光催化劑。基於紫外光譜照射,催化劑表面產生活性氧化物種,這些物種具有強氧化性能殺滅細胞。 === 本文首次研究了母體菌種大腸桿菌BW25113和它的同源單基因缺陷變異體對光催化殺菌的靈敏度差異。母體菌種和變異菌種表現出不同的耐受性。基於此,能幫助發掘出重要的變種。通過生物化學方法,可以檢測出不同菌種的生理性特徵。結合其他方法,可以進一步揭示光催化殺菌的生理性機理。 === 首先,我們篩選出了兩種...
