Effects of Cd on reductive transformation of lepidocrocite by Shewanella oneidensis MR-1

摘要：

　　We investigated the reduction of lepidocrocite(γ-FeOOH)by Shewanella oneidensis MR-1 in the presence and absence of Cd.The results showed that Cd2+retarded microbial reduction of γ-FeOOH and avoided formation of magnetite.The inhibitory effect on γ-FeOOH transformation may not result from Cd2+toxicity to the bacterium; it rather was probably due to competitive adsorption between Cd2+and Fe2+on γ-FeOOH as its surface reduction catalyzed by adsorbed Fe2+was eliminated by adsorption of Cd2+.
