| 英文摘要 | Elemental sulfur bio-oxidation by the typical acidophilic sulfur-oxidizing microbe acidithiobacillus ferrooxidans was investigated by using the technique of sulfur k-edge xanes spectroscopy. our results showed that the majority of elemental sulfur altered by a. ferrooxidans was dissolved into the organic phase containing carbon disulfide, while a part of it floated. the fitted results of sulfur k-edge xanes spectrum of the floated sulfur showed that the floating part of the elemental sulfur powder was converted to polymeric sulfur and the relative concentration of sulfur in cyclo-octasulfur s(8) and polymeric sulfur was 37.2 and 62.8%, respectively. it seems that the cyclo-octasulfur is converted to the polymeric sulfur and this appears to be necessary for oxidation of elemental sulfur by a. ferrooxidans. the results have important implications for our understanding of the mechanisms for bio-oxidation of elemental sulfur. |
