Phosphitispora fastidiosa gen. Nov. sp. nov., a new dissimilatory phosphite-oxidizing anaerobic bacterium isolated from anaerobic sewage sludge
Open accessAbstract
A new strictly anaerobic bacterium, strain DYL19 T, was enriched and isolated with phosphite as the sole electron donor and CO 2 as a single carbon source and electron acceptor from anaerobic sewage sludge sampled at a sewage treatment plant in Constance, Germany. It is a Gram-positive, spore-forming, slightly curved, rod-shaped bacterium which oxidizes phosphite to phosphate while reducing CO 2 to biomass and small amounts of acetate. Optimal growth is observed at 30 °C, pH 7.2, with a doubling time of 3 days. Beyond phosphite, no further inorganic or organic electron donor can be used, and no other electron acceptor than CO 2 is reduced. Sulphate inhibits growth with phosphite and CO 2. The G+C content is 45.95 mol%, and dimethylmenaquinone-7 is the only quinone detectable in the cells. On the basis of 16S rRNA gene sequence analysis and other chemotaxonomic properties, strain DYL19 T is described as the type strain of a new genus and species, Phosphitispora fastidiosa gen. nov., sp. nov.

The acetyl-CoA pathway can be a dedicated pathway of CO2 fixation with no role in energy metabolism, for example in sulfate reducers that grow autotrophically, or in bacteria with phosphite-dependent energy metabolism.
“The acetyl-CoA pathway can be a dedicated pathway of CO2 fixation (carbon metabolism) with no role in energy metabolism (ATP synthesis), for example in sulfate reducers that grow autotrophically, or in bacteria with phosphite-dependent energy metabolism (Mao et al., 2021).”

Phosphite is the only reductant other than H2 that is known to fuel chemolithoautotrophic growth using the acetyl-CoA pathway.

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.
