Holtiella tumoricola gen. nov. sp. nov., isolated from a human clinical sample
Bibliographic record
Abstract
The diversity of bacteria associated with biopsy material obtained from patients with colorectal cancer was investigated using culture techniques. A novel bacterium, strain CC70AT, was isolated by diluting a sample of homogenized tissue in anaerobic medium, and then plating to yield a pure culture. Strain CC70AT was a Gram-positive, strictly anaerobic, motile, rod-shaped bacterium. Formate, but not acetate, was a fermentative end-product from growth in peptone–yeast extract and peptone–yeast–glucose broth. The G+C content of DNA from strain CC70AT was 34.9 mol%. 16S rRNA gene sequence analysis revealed that the isolate was part of the phylum Bacillota . The closest described relatives of strain CC70AT were Cellulosilyticum lentocellum (93.3 %) and Cellulosilyticum ruminicola (93.3 and 91.9% sequence similarity across 16S rRNA gene, respectively). According to the data obtained in this work, strain CC70AT represents a novel bacterium belonging to a new genus for which the name Holtiella tumoricola gen. nov., sp. nov. is proposed. The type strain for our described novel species is CC70AT (=DSM 27931T= JCM 30568T).

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.
