Abstract
Abstract Pseu.do.bac.te.ro'i.des. Gr. adj. pseudês false; N.L. masc. n. Bacteroides a bacterial generic name; N.L. masc. n. Pseudobacteroides false Bacteroides , so named for the original misclassification of the type species. Cells are Gram‐stain‐negative, thermotolerant, non‐spore‐forming, nonmotile, and strictly anaerobic rods (0.8–6 μm), occurring singly, in pairs, or occasionally in chains of up to eight cells. Cells grow at 20–45°C, with an optimum at 40°C and pH 6.0–8.0, with an optimum at 7.0. Cells tolerate the heat treatment at 75°C for 10 min. Growth occurs by anaerobic fermentation of cellobiose and recalcitrant cellulosic materials. The major fermentation products are acetate, ethanol, H 2 , and CO 2 . The major cellular fatty acids are C 16:0 , iso‐C 15:0 , and C 16:0 . The closest relative of the genus Pseudobacteroides is the genus Anaerobacterium based on 16S rRNA gene sequence analysis. Phylogenetically, a member of the family Oscillospiraceae in the phylum Firmicutes . The genus Pseudobacteroides contains one species with a validly published name Pseudobacteroides cellulosolvens isolated from a methanogenic cellulose enrichment culture of municipal sewage sludge in Canada. DNA G + C content (mol%) : 35.6 (genome analysis). Type species : Pseudobacteroides cellulosolvens Horino et al. 2014 VP ( Bacteroides cellulosolvens Murray et al. 1984 VP ). Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the genus Pseudobacteroides is: correct name (last update, February 2025) * . LPSN classification: Bacteria / Bacillati / Bacillota / Clostridia / Eubacteriales / Oscillospiraceae / Pseudobacteroides The genus Pseudobacteroides can also be recovered in the Genome Taxonomy Database (GTDB) as g__Pseudobacteroides (version v220) ** . GTDB classification: d__Bacteria / p__Bacillota_A / c__Clostridia / o__Acetivibrionales / f__DSM-2933 / g__Pseudobacteroides * Meier‐Kolthoff et al. ( 2022 ).

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.
