Abstract
Abstract Delf'tia. M.L. fem. n. Delftia referring to the city of Delft, the site of isolation of the type species, and in recognition of the role of Delft research groups in the development of bacteriology. Cells are straight to slightly curved rods , 0.4–0.8 × 2.5–4.1 µm (occasionally up to 7 µm), occurring singly or in pairs . Motile by means of polar or bipolar tufts of one to five flagella . Do not produce endospores. Gram negative. Oxidase and catalase positive . No fluorescent pigment produced. Poly‐β‐hydroxybutyrate is accumulated. Aerobic , having a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor. Nonfermentative. Reduce nitrate to nitrite. Do not denitrify. Chemoorganotrophic . Good growth occurs on media containing organic acids, amino acids, peptone, and carbohydrates. Utilize mannitol and fructose as the sole carbon source, but not glucose. No autotrophic growth with H 2 . Hydrolyze acetamide. No levan formation from sucrose. Arginine dihydrolase absent. Meta cleavage of protocatechuate. Lipase (Tween 80 hydrolysis) positive. Main polyamines are putrescine and 2‐hydroxyputrescine . The major quinone is ubiquinone Q‐8 ; minor quinones are Q‐7 and Q‐9. Major fatty acids are hexadecanoic acid (C 16:0 ), hexadecenoic acid (C 16:1 ), and octadecenoic acid (C 18:1 ). 3‐hydroxy fatty acids (C 10:0 3OH and C 8:0 3OH ) but not 2‐hydroxy fatty acids are present. DNA–rRNA hybridization and 16S rRNA sequence analysis places the genus in the family Comamonadaceae . Isolated from soil, sediment, activated sludge, crude oil, oil brine, water, and various clinical samples. The mol % G + C of the DNA is : 67–69. Type species : Delftia acidovorans (den Dooren de Jong 1926) Wen, Fegan, Hayward, Chakraborty and Sly 1999, 573 ( Pseudomonas acidovorans den Dooren de Jong 1926, 106; Comamonas acidovorans (den Dooren de Jong 1926) Tamaoka, Ha and Komagata 1987, 58.) Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the genus Delftia is: correct name (last update, February 2025) * . LPSN classification: Bacteria / Pseudomonadati / Pseudomonadota / Betaproteobacteria / Burkholderiales / Comamonadaceae / Delftia The genus Delftia can also be recovered in the Genome Taxonomy Database (GTDB) as g__Comamonas (version v220) ** . GTDB classification: d__Bacteria / p__Pseudomonadota / c__Gammaproteobacteria / o__Burkholderiales / f__Burkholderiaceae / g__Comamonas * 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.
