Surface Changes of Ochrobactrum Anthropi in Cr(Ⅵ) Treatment for 1 Hour

Bioremediation has been a considerable method for treating Cr(Ⅵ) contamination. Bacterial surface changes of Ochrobactrum anthropi during Cr biosorption was investigated in this study. We found that Cr adsorption capacity increased with the increase of initial Cr(Ⅵ) concentration. Atomic force microscope (AFM) morphologic analysis combined with surface roughness analysis indicated that the bacterial surfaces became rougher during Cr uptake process. X-ray photoelectron spectroscopy (XPS) showed that Cr(Ⅲ) was adsorbed on the bacterial surfaces. Fourier transform infrared (FT-IR) analysis showed that surface functional groups including C-O and C-N might be involved in the Cr biosorption process.
