Abstract
A novel thermophilic, sulfur-oxidizing Gram-negative bacterium, designated strain SS-5T, was isolated from the Calcite Hot Springs in Yellowstone National Park, USA. The cells were motile rods (1.2-2.8 microm long and 0.6-0.8 microm wide). The new isolate was a facultative heterotroph capable of using elemental sulfur or thiosulfate as an electron donor and O2 (1-18 %; optimum 6 %, v/v) as an electron acceptor. Hydrogen did not support growth. The isolate grew autotrophically with CO2. In addition, strain SS-5T utilized various organic carbon sources such as yeast extract, tryptone, sugars, amino acids and organic acids. Growth was observed between 55 and 78 degrees C (optimum 70 degrees C; 3.5 h doubling time), pH 6.0 and 8.0 (optimum pH 7.5), and 0 and 0.6 % (w/v) NaCl (optimum 0 %). The G+C content of the genomic DNA was 32 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the isolate was a member of the genus Sulfurihydrogenibium. On the basis of the physiological and molecular characteristics of the new isolate, we propose the name Sulfurihydrogenibium yellowstonense sp. nov. with SS-5T (=JCM 12773T=OCM 840T) as the type strain. In addition, emended descriptions of the genus Sulfurihydrogenibium, Sulfurihydrogenibium subterraneum and Sulfurihydrogenibium azorense are proposed.

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 it
