Negativibacillus is a genus of strictly anaerobic, Gram-stain-negative, spore-forming, non-motile, rod-shaped bacteria in the phylum Bacillota.[1] The type species and only species with a validly published name is Negativibacillus massiliensis.[2]
Description
[edit]The type strain of N. massiliensis, Marseille-P3213, was isolated from a human left-colon sample. Its cells are approximately 0.5–0.8 μm wide and 3.0–4.5 μm long. The bacterium grows under strictly anaerobic conditions, with optimal growth at 37 °C, and is catalase- and oxidase-negative.[1]
The genome of the type strain is approximately 2.88 million base pairs long and has a G+C content of approximately 45.4%. The strain is deposited in culture collections as CSUR P3213 and DSM 103594.[1][3]
Taxonomy
[edit]The generic name combines the Latin negativus, meaning negative, and bacillus, meaning a small rod, referring to the Gram-stain-negative appearance and rod-shaped cells of the type species. The specific epithet massiliensis refers to Massilia, the Roman name for Marseille.[2][3]
The original description assigned the genus to the family Ruminococcaceae. LPSN currently treats Negativibacillus as unassigned to a family within Bacillota.[1][2]
