Reclassification of some species of Thiobacillus to the newly designated genera Acidithiobacillus gen. nov., Halothiobacillus gen. nov. and Thermithiobacillus gen. nov.

“…sulfur springs, sulfide minerals, sulfur deposits, sewage-treatment areas and sources of sulfur gases, such as H # S from sediments or anaerobic soils). Analysis of 16S rRNA sequences has revealed a diversity and misclassification among the thiobacilli at least as profound as that shown many years ago, by classical means, for the ' hydrogen bacteria ', which were subsequently reclassified into diverse genera (Davis et al, 1969).…”

Bacillus schlegelii, a New Species of Thermophilic, Facultatively Chemolithoautotrophic Bacterium Oxidizing Molecular Hydrogen

“…Aerobic, hydrogen-oxidizing bacteria form a physiological group comprising bacteria from various taxa (Davis et al, 1969(Davis et al, , 1970Aragno et al, 1977;. Mesophilic, spore-forming, hydrogen-oxidizing bacteria, among them Bacillus pycnoticus, were isolated by Ruhland (1 922, 1924) and Grohmann (1924).…”

Paracoccus lutimaris sp. nov., isolated from a tidal flat sediment

“…The genus Paracoccus, a member of the Alphaproteobacteria, was proposed by Davis et al (1969) to accommodate a Gram-negative, catalase-and oxidase-positive, coccoid bacterium, Paracoccus denitrificans. At the time of writing, the genus Paracoccus was represented by 37 species with validly published names, isolated from various environments including soil, sediment and activated sludge.…”
