Sneathiella aquimaris sp. nov., isolated from aquaculture seawater
Bibliographic record
Abstract
A novel marine bacterium, designated strain 216LB-ZA1-12 T , was isolated from a Penaeus vannamei aquaculture seawater sample. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 216LB-ZA1-12 T belonged to the genus Sneathiella , with the highest sequence similarity to Sneathiella glossodoripedis MKT133 T (97.7 %), followed by Sneathiella limimaris GH1-24 T (97.0 %), Sneathiella chungangensis CAU 1294 T (96.6 %) and Sneathiella chinensis LMG 23452 T (96.1 %). The average nucleotide identity and the DNA–DNA hybridization estimate values between strain 216LB-ZA1-12 T and four close type strains were between 69.2–71.3% and 16.7–17.8 %, respectively. The bacterium was Gram-stain-negative, facultatively anaerobic, oxidase and catalase positive, oval- to rod-shaped, and motile. Growth was observed at pH 7–9, salinities of 1–15% and temperatures of 4–42 °C. The G+C content of the chromosomal DNA was 48.50 mol%. The major respiratory quinone was determined to be Q-10. The principal fatty acids were summed feature 8 (C 18 : 1 ω 7c/ ω 6c ) and C 16 : 0 . The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and aminophospholipid. The combined genotypic and phenotypic data show that strain 216LB-ZA1-12 T represents a novel species within the genus Sneathiella , for which the name Sneathiella aquimaris sp. nov. is proposed, with the type strain 216LB-ZA1-12 T (=MCCC 1A14570 T =KCTC 72144 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.
