The importance of hydrogen in landfill fermentations
Article Abstract:
Methanogenesis, hydrogen concentrations and pHs are measured in 42 soil samples taken from two different landfills to determine the role played by hydrogen in landfill fermentation. Results suggest that high levels of hydrogen concentration leads to the formation of volatile fatty acids which aid landfill methanogenesis. This finding indicates that hydrogen can be used to accurately monitor the status of landfill fermentations.

Benzoate fermentation by the anaerobic bacterium Syntrophus aciditrophicus in the absence of hydrogen-using microorganisms
Article Abstract:
Syntrophus aciditrophicus can ferment benzoate to acetate and carbon dioxide in the absence of a hydrogen-using microorganism by using one of the reaction products as the electron acceptor. The reducing equivalents produced during the oxidation of benzoate are used to reduce another molecule of benzoate to cyclohexane carboxylate.

Thiosulfate disproportionation by Desulfotomaculum thermobenzoicum
Article Abstract:
Scientists report the first known case of a gram-positive, thermophilic sulfate-reducing bacterium that can grow by thiosulfate disproportionation. Until now, only gram-negative, sulfate-reducing bacteria in the delta subclass of the Proteobacteria were known to do this.
