On the basis of physiological characters and 16S rRNA gene sequence comparisons, eight of the existing Thiobacillus species are proposed for reassignment to three newly designated genera within the gamma-subclass of the Proteobacteria. Expand
Oxidative metabolism of inorganic sulfur compounds by bacteria
Evidence of convergent evolution among diverse bacterial groups to achieve the end of energy-yielding sulfur compound oxidation (to drive autotrophic growth on carbon dioxide) but using a variety of enzymological systems, which share some common features is presented. Expand
Studies on the growth of Thiobacillus ferrooxidans
The results suggest that inhibition of T. ferrooxidans by agar is a result of the acid hydrolysis of agar, the main product of which is d-galactose. Expand
The Genome Sequence of the Obligately Chemolithoautotrophic, Facultatively Anaerobic Bacterium Thiobacillus denitrificans
The genome sequence of T. denitrificans will enable elucidation of the mechanisms of aerobic and anaerobic sulfur-compound oxidation by beta-proteobacteria and will help reveal the molecular basis of this organism's role in major biogeochemical cycles and groundwater restoration. Expand

The relations between oxidation mechanisms, substrate-level and electron transport-dependent phosphorylation, energy-dependent NAD+ reduction and efficiency of growth are assessed in order to evaluate the efficiency of energy conservation in different species. Expand
Desulfonation of propanesulfonic acid by Comamonas acidovorans strain P53: evidence for an alkanesulfonate sulfonatase and an atypical sulfite dehydrogenase
Evidence is presented for the presence in propanesulfonate-grown Comamonas acidovorans strain P53 of a cytoplasmically located sulfonatase that does not sediment at 100,000 × g, indicating a monooxygenase that effects the addition of molecular oxygen to C3-C6 1-alkanesulf onates. Expand
Studies on the growth of Thiobacillus ferrooxidans
Bacteria grown on thiosulphate or tetrathionate could produce colonies on ferrous iron agar, but this ability declined on prolonged culture on sulphur compounds, which was investigated in detail. Expand
A novel pink-pigmented facultative methylotroph, Methylobacterium thiocyanatum sp. nov., capable of growth on thiocyanate or cyanate as sole nitrogen sources
The isolation and properties of a novel species of pink-pigmented methylotroph, Methylobacterium thiocyanatum, are described. This organism satisfied all the morphological, biochemical, andExpand

Abstract The free-energy data on which assessments of the autotrophic growth efficiencies of chemolithotrophic bacteria are commonly based have been reevaluated and new values have been calculated.Expand
