The mechanism of action of Sterilox, a non-toxic liquid biocide produced by electrolysis of a dilute saline solution, upon planktonic cells of Escherichia coli JM109 was investigated using protein and nucleic acid analysis. The results revealed total destruction of chromosomal and plasmid DNA, RNA and proteins of E. coli within 5 min of exposure. Our earlier investigation conducted using atomic force microscopy imaging revealed swelling and rupture of E. coli cells with release of cytoplasm. We propose that the biocidal properties of Sterilox are due to its effect upon constituents of the bacterial cell including proteins and nucleic acids.
通过蛋白质和核酸分析,研究了由稀盐溶液电解产生的无毒液体杀菌剂Sterilox对大肠杆菌JM109浮游细胞的作用机制。结果显示,暴露5分钟内,大肠杆菌的染色体和质粒DNA、RNA及蛋白质被完全破坏。我们早期使用原子力显微镜成像进行的研究显示,大肠杆菌细胞肿胀并破裂,细胞质释放。我们认为,Sterilox的杀菌特性归因于其对细菌细胞成分(包括蛋白质和核酸)的作用。
