Abstract
Several barophilic and barotolerant bacteria were isolated from deep-sea mud samples of Suruga Bay (2485 m depth), the Ryukyu Trench (5110 m depth), and the Japan Trench (land-side 6356 m, and sea-side 6269 m depth, respectivelys. The barophilic bacteria, strains DB5501, DB6101, DB6705 and DB6906, were albe to grow better under high hydrostatic pressures than under atmospheric pressure (0.1 megapascals; MPa). The optimal growth pressures for the barophilic bacteria were approximately 50 MPa at 10°C. The barotolerant strains DSK1 and DSS12 were determined to be psychrophilic, and had optimal growth temperatures of 10°C and 8°C, respectively. The degree of barophily and barotolerance was shown to be very dependent on temperature. For example, at 4°C the barophilic strains were indistinguishable from barotolerant bacteria, whereas at 15°C the barotolerant strains behaved more like the barophilic strains. Based on sequence analysis of 16S ribosomal DNA, all of the strains included in this study belong to the gamma subgroup of the Proteobacteria. Phylogenetic relations between the isolated strains and the known gamma subgroup bacteria suggested that the isolated strains belong to a new sub-branch of this group.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
