Abstract
Anionic surfactant-biodegrading capability of an <i>Arcobacter
butzleri</i> strain was analyzed under aerobic conditions.
The <i>A. butzleri</i>
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.
