Rhodocyclus purpureus gen. nov. and sp. nov., a Ring-Shaped, Vitamin B12-Requiring Member of the Family Rhodospirillaceae
Abstract
The dominant phototrophic bacterium in a water sample from a purplish red waste-water lagoon was isolated in pure culture. The individual cells of this organism were half-ring-shaped and ring-shaped before cell division; the half-rings were 0.6 to 0.7 μm wide and 2.5 to 3.0 μm long. Open or compact coils of variable length were also formed. Acetate, pyruvate, and cyclohexane carboxylate were the carbon sources best utilized by this organism; vitamin B12, p-aminobenzoic acid, and biotin were required as growth factors. The photosynthetic pigments produced by the organism are bacteriochlorophyll αp and carotenoids of the rhodopinal series. The new bacterium was facultatively aerobic and was unable to photooxidize sulfide or thiosulfate to sulfur or sulfate. It belongs to the family Rhodospirillaceae and is described herein as a member of a new genus, Rhodocyclus. The name proposed for this new species is Rhodocyclus purpureus. The type strain of R. purpureus is “Ames” 6770 (= DSM 168).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
