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 RKSG073T, was isolated from the sea spongeAplysina 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. RKSG073Tgrew optimally at 30–37 °C, pH 6–7, and with 2–3 % (w/v) NaCl. The predominant fatty acids of RKSG073Twere summed feature 8 (C18 : 1ω6cand/or C18 : 1ω7c) and C16 : 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 RKSG073Tin a clade with its closest relative Aestuariispira insulae AH-MY2T(92.1 % 16S rRNA gene sequence similarity), which subsequently clustered with Hwanghaeella grinnelliae Gri0909T, Marivibrio halodurans ZC80Tand type species of the genera Kiloniella , Thalassospira and Terasakiella . The DNA G+C content calculated from the genome of RKSG073Twas 42.2 mol%. On the basis of phylogenetic distinctiveness and polyphasic analysis, here we propose that RKSG073T(culture deposit numbers: ATCC collection = TSD-74T, BCCM collection = LMG 29869T) represents the type strain of a novel genus and species within the family Kiloniellaceae , order Rhodospirillales and class Alphaproteobacteria , for which the nameCurvivirga aplysinaegen. nov., sp. nov. is proposed.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
