Anionic surfactant-biodegrading capability of an Arcobacter butzleri strain was analyzed under aerobic conditions. The A. butzleri isolate displayed efficient surfactant-biodegrading capacity for sodium dodecyl sulfate (SDS) at concentrations of up to 100 mg/L in 6 days, corresponding to 99.0% removal efficiency. Fourier transform infrared spectroscopy was applied to observe the effects of varying concentrations of SDS on the biochemistry of bacterial cells. Results suggest that protein secondary structures were altered in bacterial cells at sufficiently high SDS concentrations, concurrent with SDS biodegradation.
在有氧条件下分析了弧菌属但兹勒氏菌（Arcobacter butzleri）菌株的阴离子表面活性剂降解能力。该弧菌属分离株在 6 天内可有效降解高达 100mg/L 的十二烷基硫酸钠（SDS），去除效率达 99.0%。傅里叶变换红外光谱用于观察不同浓度 SDS 对细菌细胞生化特性的影响。结果表明，在足够高的 SDS 浓度下，细菌细胞的蛋白质二级结构发生了改变，同时 SDS 也被生物降解。
