Abstract
Abstract Ther.mo.to.ga.ce'ae. N.L. fem. n. Thermotoga , type genus of the family; L. suff. ‐ aceae , ending to denote a family; N.L. fem. pl. n. Thermotogaceae , the family of Thermotoga . The family Thermotogaceae comprises sheathed thermophilic and hyperthermophilic, anaerobic, fermentative, and hydrogen‐producing bacteria. Cells are rod shaped, occurring singly, in pairs, or in chains. Cells are surrounded with sheaths, the so‐called togas. In stationary phase, they might look like “balloons.” Gram‐negative. Colonies are circular, convex, and vary in color from white to cream. The members of the family grow well on complex organic media and utilize a broad spectrum of carbon sources. Optimal growth at 60–80°C. Reduce thiosulfate and, in some cases, elemental sulfur, to sulfide. The family currently accommodates two genera, Thermotoga and Pseudothermotoga . The members of the family were isolated from geothermal heated marine sediments, shallow submarine thermal vents, hot springs, solfataric springs, oil reservoirs, and thermophilic bioreactors. DNA G + C content (mol%) : 38.7–51.3%.

Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the family Thermotogaceae is: correct name (last update, April 2026) * . LPSN classification: Bacteria / Thermotogati / Thermotogota / Thermotogae / Thermotogales / Thermotogaceae The family Thermotogaceae can also be recovered in the Genome Taxonomy Database (GTDB) as f__Thermotogaceae (version v232) ** .

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
