Marinobacter psychrophilus sp. nov., a psychrophilic bacterium isolated from the Arctic
Bibliographic record
Abstract
Strain 20041(T) was isolated from sea-ice of the Canadian Basin (7 degrees 23' 14'' N 14 degrees 06' 55'' W). Phylogenetic analysis based on 16S rRNA gene homology showed that strain 20041(T) was related to members of the genus Marinobacter and had highest 16S rRNA gene sequence similarity with the type strain of Marinobacter maritimus. Cells were Gram-negative, rod-shaped, psychrophilic and motile. The temperature range for growth was 0-22 degrees C, with optimum growth occurring at 16-18 degrees C and at approximately pH 6.0-9.0. Strain 20041(T) had ubiquinone-9 as the major respiratory quinone and iso-C(15 : 0) 2OH and/or C(16 : 1)omega7c, C(16 : 0), C(18 : 1)omega9c and C(12 : 0) 3OH as major fatty acids. The genomic DNA G+C content was 55.4 mol%. On the basis of the phenotypic characteristics, phylogenetic analysis and DNA-DNA relatedness data, strain 20041(T) is considered to represent a novel species, for which the name Marinobacter psychrophilus sp. nov. is proposed. The type strain is 20041(T) (=CGMCC 1.6499(T)=JCM 14643(T)).

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.
