Abstract
Abstract Pe.tro.to.ga'ce.ae. N.L. fem. n. Petrotoga , type genus of the family; L. fem. pl. n. suff. ‐aceae , ending to denote a family; N.L. fem. pl. n. Petrotogaceae , the family whose nomenclatural type is the genus Petrotoga . The family Petrotogaceae , the only family in the order Petrotogales , comprises mesophilic and thermophilic bacteria, which grow optimally at salinities that range from freshwater to sea water. The family currently accommodates six genera: Defluviitoga , Geotoga , Marinitoga , Oceanotoga , Petrotoga , and Tepiditoga . Several 16S rRNA sequences and metagenomes from environmental samples suggest that Petrotogaceae may include additional genera whose representatives are not yet isolated. The cells are sheathed rods that can form chains. The cells stain Gram‐negative. Members of this family are heterotrophs and anaerobes. Sulfur is reduced by all the type strains of the six genera. Thiosulfate is reduced by the members of the genera Defluviitoga , Geotoga , Oceanotoga , and Tepiditoga . Known habitats are shallow and deep‐sea hydrothermal vents, terrestrial hot springs, oils and gas reservoirs, and human‐made environments, such as biogas reactors, landfills, and wastewater. DNA G + C content (mol%) : 25.8–34.1 (genome analysis). Type genus : Petrotoga Davey et al. 1993, VL47. Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the family Petrotogaceae is: correct name (last update, February 2025) * . LPSN classification: Bacteria / Thermotogati / Thermotogota / Thermotogae / Petrotogales / Petrotogaceae The family Petrotogaceae can also be recovered in the Genome Taxonomy Database (GTDB) as f__Petrotogaceae (version v220) ** .

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.
