Abstract
Abstract Me.thy.lo.ha.lo'bi.us. N.L. neut. n. methylum , the methyl group; Gr. masc. n. hals , halos salt; Gr. masc. n. bios life; N.L. masc. n. Methylohalobius salt requiring, methyl‐using life. The genus Methylohalobius comprises moderately halophilic, obligately methanotrophic bacteria. They have the highest salt tolerance of any methanotroph yet cultured, growing optimally at 1–1.5 M NaCl and tolerating NaCl concentrations up to 2.5 M (14.6% w/v). A complete genome sequence of the type strain is available. Cells are Gram‐negative, aerobic, nonpigmented, motile, coccoid, or spindle‐shaped and occur singly, in pairs, or in short chains. An extensive intracytoplasmic membrane system common to gammaproteobacterial methanotrophs is present. Growth occurs on methane and methanol. Carbon is assimilated via the ribulose monophosphate pathway. The genus Methylohalobius belongs to the class Gammaproteobacteria , family Methylothermaceae , and includes a single species, Methylohalobius crimeensis . The DNA G + C content is 58.3% based on complete genome sequencing. Known habitats are hypersaline lakes. DNA G + C content (mol%) : 58.3 (genome analysis). Type species : Methylohalobius crimeensis Heyer, Berger, Hardt, and Dunfield 2005, 1824 VP . Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the genus Methylohalobius is: correct name (last update, February 2025) * . LPSN classification: Bacteria / Pseudomonadati / Pseudomonadota / Gammaproteobacteria / Methylococcales / Methylothermaceae / Methylohalobius The genus Methylohalobius can also be recovered in the Genome Taxonomy Database (GTDB) as g__Methylohalobius (version v220) ** . GTDB classification: d__Bacteria / p__Pseudomonadota / c__Gammaproteobacteria / o__Methylococcales / f__Methylothermaceae / g__Methylohalobius * 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.
