The Production and Utilization of Intermediary Elemental Sulfur During the Oxidation of Reduced Sulfur-Compounds by Thiobacillus-Ferrooxidans
TL;DR: Thiobacillus ferrooxidans, an acidophilic chemolithoautotroph, was found to produce an insoluble sulfur compound, primarily elemental sulfur, during the oxidation of thiosulfate, trithionate, tetrathionate and sulfide.
Journal ArticleDOI

TL;DR: The localization of the major anammox protein, hydrazine oxidoreductase, was determined via immunogold labelling to be inside the anamm oxosome, and it was suggested that theAnammox bacteria may also use organic acids to convert nitrate and nitrite into dinitrogen gas when ammonia is in short supply.
Journal ArticleDOI
Heterotrophic nitrification and aerobic denitrification in Alcaligenes faecalis strain TUD.
TL;DR: Comparison of the behaviour of A. faecalis TUD with that of other bacteria capable of heterotrophic nitrification and aerobic denitrification established that the response of these organisms to environmental parameters is not uniform.
Journal ArticleDOI
Isolation and characterization of a novel facultatively alkaliphilic Nitrobacter species, N. alkalicus sp. nov.
TL;DR: The new isolates from the alkaline habitats are described as a new species of the genus Nitrobacter, N. alkalicus, on the basis of their substantial morphological, physiological, and genetic differences from the recognized neutrophilic representatives of this genus.
Journal ArticleDOI
Competition between the Facultatively Chemolithotrophic Thiobacillus-A2, an Obligately Chemolithotrophic Thiobacillus and a Heterotrophic Spirillum for Inorganic and Organic Substrates
TL;DR: Competition in a chemostat between the versatile Thiobacillus A2 and the specialized T. neapolitanus for thiosulfate as the sole growth-limiting substrate, led to dominance of the specialized over the versatile organism, at dilution rates ≥0.025 h-1.07, interpreted as evidence that T. A2 was growing mixotrophically.
