Abstract
Abstract Ther.mo.si'pho. Gr. fem. n. thermê , heat; L. masc. n. sipho , little pipe to suck drinks through, a tube; N.L. masc. n. Thermosipho , the hot tube, due to the sheath surrounding the bacteria. The genus Thermosipho is currently composed of eight species ( Thermosipho africanus , Thermosipho melanesiensis , Thermosipho japonicus , Thermosipho geolei , Thermosipho atlanticus , Thermosipho affectus , Thermosipho globiformans , and Thermosipho activus ). The rods are surrounded by an outer sheath‐like toga, and some rods form spheroids during growth. The spheroids may produce “immature progenies” that are too small to contain a complete genome, which need further investigation to elucidate their function. The cells are obligately anaerobic , thermophilic , with optimum growth temperature of 65–75°C, optimal pH 6.0–7.5, and optimal growth under low salinity 2.0–3.0% NaCl. Heterotrophic growth . Sulfur is reduced to H 2 S by all the species, while thiosulfate is reduced by Thermosipho africanus and Thermosipho japonicus . Molecular hydrogen inhibits growth. Two described Thermosipho spp. are capable of de novo biosynthesis of vitamin B12. Members of the phylum Thermotogota , class Thermotogae , order Thermotogales , and family Fervidobacteriaceae . Known habitats are shallow and deep‐sea hydrothermal vents and deep subsurface oil reservoirs. DNA G + C content (mol%) : 29.5–31.5 ( T m and genome analysis). Type species : Thermosipho africanus Huber et al. 1989, VL31 emend. Ravot et al. 1996. Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the genus Thermosipho is: correct name (last update, February 2025) * . LPSN classification: Bacteria / Thermotogati / Thermotogota / Thermotogae / Thermotogales / Fervidobacteriaceae / Thermosipho The genus Thermosipho can also be recovered in the Genome Taxonomy Database (GTDB) as g__Thermosipho (version v220) ** . GTDB classification: d__Bacteria / p__Thermotogota / c__Thermotogae / o__Thermotogales / f__Fervidobacteriaceae / g__Thermosipho * Meier‐Kolthoff et al. ( 2022 ).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
