Sneathiella aquimaris sp. nov., isolated from aquaculture seawater
Bibliographic record
Abstract
A novel marine bacterium, designated strain 216LB-ZA1-12T, was isolated from a Penaeus vannamei aquaculture seawater sample. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 216LB-ZA1-12T belonged to the genus Sneathiella , with the highest sequence similarity to Sneathiella glossodoripedis MKT133T (97.7 %), followed by Sneathiella limimaris GH1-24T (97.0 %), Sneathiella chungangensis CAU 1294T (96.6 %) and Sneathiella chinensis LMG 23452T (96.1 %). The average nucleotide identity and the DNA–DNA hybridization estimate values between strain 216LB-ZA1-12T 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 (C18 : 1 ω7c/ω6c) and C16 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and aminophospholipid. The combined genotypic and phenotypic data show that strain 216LB-ZA1-12T represents a novel species within the genus Sneathiella , for which the name Sneathiella aquimaris sp. nov. is proposed, with the type strain 216LB-ZA1-12T (=MCCC 1A14570T=KCTC 72144T).

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.
