Characterization of the ability of DSM 15643 and DSM 20482 strains in the presence of Cu and HO to reactive oxygen species generation. Spectrophotometric ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) method was used. Determination of: MIC for Cu, HO and ABTS; survivability of under atmospheric oxygen exposure; the level and rate constants of free radicals production by the bacteria. in the presence of Cu and HO is able to generate free radicals. Reactive oxygen species are produced mainly outside the bacterial cell, which suggests that outer membrane proteins may be involved in oxidative process.
研究 DSM 15643 和 DSM 20482 菌株在 Cu 和 HO 存在下产生活性氧物质的能力。采用分光光度 ABTS(2,2'-偶氮双(3-乙基苯并噻唑啉-6-磺酸))法。测定:Cu、HO 和 ABTS 的 MIC;在大气氧暴露下的生存能力;细菌产生自由基的水平和速率常数。在 Cu 和 HO 的存在下能够产生自由基。活性氧主要在细菌细胞外产生,这表明外膜蛋白可能参与氧化过程。
