- W2109103681 abstract "A new chemolithotrophic bacterial metabolism was discovered in anaerobic marine enrichment cultures. Cultures in defined medium with elemental sulfur (S 0 ) and amorphous ferric hydroxide (FeOOH) as sole substrates showed intense formation of sulfate. Furthermore, precipitation of ferrous sulfide and pyrite was observed. The transformations were accompanied by growth of slightly curved, rod-shaped bacteria. The quantification of the products revealed that S 0 was microbially disproportionated to sulfate and sulfide, as follows: 4S 0 + 4H 2 O → SO 4 2- + 3H 2 S + 2H + . Subsequent chemical reactions between the formed sulfide and the added FeOOH led to the observed precipitation of iron sulfides. Sulfate and iron sulfides were also produced when FeOOH was replaced by FeCO 3 . Further enrichment with manganese oxide, MnO 2 , instead of FeOOH yielded stable cultures which formed sulfate during concomitant reduction of MnO 2 to Mn 2+ . Growth of small rod-shaped bacteria was observed. When incubated without MnO 2 , the culture did not grow but produced small amounts of SO 4 2- and H 2 S at a ratio of 1:3, indicating again a disproportionation of S 0 . The observed microbial disproportionation of S 0 only proceeds significantly in the presence of sulfide-scavenging agents such as iron and manganese compounds. The population density of bacteria capable of S 0 disproportionation in the presence of FeOOH or MnO 2 was high, > 10 4 cm -3 in coastal sediments. The metabolism offers an explanation for recent observations of anaerobic sulfide oxidation to sulfate in anoxic sediments." @default.
