摘要: Members of the genus Clostridia can reduce Pd(II) ions to form metallic Pd nanoparticles (bio-Pd). Cultures C. pasteurianum BC1 were used generate bio-Pd, which is primarily formed on microbial cell wall. Batch experiments using cells loaded with bio-Pd showed efficient reduction organic azo dyes, methyl orange and Evans blue, while little dyes was observed in control Pd-containing heat-killed cultures or Pd-free viable bacterial cultures. Degradation found occur via reductive hydrogenation azo-linkage. Molecular hydrogen, concomitantly generated by pasteurianum, reaction. The process described this study a potentially alternative current groundwater wastewater treatment technologies that fail adequately degrade large quantities
