Abstract
Abstract Pseu.do.ther.mo.to'ga. Gr. adj. pseudo , false; N.L. fem. n. Thermotoga, a bacterial genus; N.L. fem. n. Pseudothermotoga, a genus falsely (or incorrectly) classified as Thermotoga . The genus Pseudothermotoga comprises sheathed, thermophilic, anaerobic, fermentative, and hydrogen‐producing bacteria. Thiosulfate is reduced by all the strains of the genus. Pseudothermotoga spp. are members of the phylum Thermotogota , class Thermotogae, order Thermotogales , family Thermotogaceae . Known habitats are hot springs, oil reservoirs, and thermophilic bioreactors. Genome sizes are in the range 2.01–2.19 Mb, and GC content varies between 38.7 and 51.3%. Based on phylogenomic analyses, two recently described species, Thermotoga profunda and Thermotoga caldifontis, should be assigned to the recently described genus Pseudothermotoga . Based on DNA–DNA hybridization and various genomic measurements, the Pseudothermotoga lettingae and Pseudothermotoga subterranea species should be reclassified as subspecies of Pseudothermotoga elfii . With these proposed reclassifications, the genus Pseudothermotoga would consist of five described species: Pseudothermotoga thermarum, Pseudothermotoga elfii, Pseudothermotoga hypogea, Pseudothermotoga Profunda, and Pseudothermotoga caldifontis . However, high genomic divergence observed within this genus may require additional taxonomic revisions in the future. DNA G + C content (mol%) : 38.7–51.3. Type species : Pseudothermotoga thermarum Bhandari and Gupta, 2014, VL158 (Basonym: Thermotoga thermarum, Windberger et al. 1989 ). Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the genus Pseudothermotoga is: correct name (last update, February 2025) * . LPSN classification: Bacteria / Thermotogati / Thermotogota / Thermotogae / Thermotogales / Thermotogaceae / Pseudothermotoga The genus Pseudothermotoga can also be recovered in the Genome Taxonomy Database (GTDB) as g__Pseudothermotoga (version v220) ** .

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.
