Curvivirga aplysinae gen. nov., sp. nov., a marine bacterium isolated from the sea sponge Aplysina fistularis
Bibliographic record
Abstract
A Gram-stain-negative, strictly aerobic, motile bacterium, designated strain RKSG073 T , was isolated from the sea sponge Aplysina fistularis , collected off the west coast of San Salvador, The Bahamas. Cells were curved-to-spiral rods with single, bipolar (amphitrichous) flagella, oxidase- and catalase-positive, non-nitrate-reducing and required salt for growth. RKSG073 T grew optimally at 30–37 °C, pH 6–7, and with 2–3 % (w/v) NaCl. The predominant fatty acids of RKSG073 T were summed feature 8 (C 18 : 1 ω6 c and/or C 18 : 1 ω7 c ) and C 16 : 0 . Major isoprenoid quinones were identified as Q-10 and Q-9. Phylogenetic analyses of nearly complete 16S rRNA genes and genome sequences positioned strain RKSG073 T in a clade with its closest relative Aestuariispira insulae AH-MY2 T (92.1 % 16S rRNA gene sequence similarity), which subsequently clustered with Hwanghaeella grinnelliae Gri0909 T , Marivibrio halodurans ZC80 T and type species of the genera Kiloniella , Thalassospira and Terasakiella . The DNA G+C content calculated from the genome of RKSG073 T was 42.2 mol%. On the basis of phylogenetic distinctiveness and polyphasic analysis, here we propose that RKSG073 T (culture deposit numbers: ATCC collection = TSD-74 T , BCCM collection = LMG 29869 T ) represents the type strain of a novel genus and species within the family Kiloniellaceae , order Rhodospirillales and class Alphaproteobacteria , for which the name Curvivirga aplysinae gen. nov., sp. nov. is proposed.

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.
