Spathaspora cesarfonsecae sp. nov., a xylose‐fermenting yeast isolated from gut of passalid beetles and rotting wood in the Amazonian rainforest biome
Bibliographic record
Abstract
Two yeast isolates of a novel d -xylose-fermenting species were obtained from rotting wood and gut of a passalid beetle collected in the Brazilian Amazonian Rainforest biome. Sequence analysis of the internal transcribed spacer–5.8S region and the D1/D2 domains of the LSU rRNA gene showed that the isolates represent a novel species of the genus Spathaspora , phylogenetically related to Spathaspora passalidarum . The yeast produced asci with a single malformed elongated ascospore with curved ends. The name Spathaspora cesarfonsecae sp. nov. is proposed to accommodate the novel species. The holotype of Sp. cesarfonsecae is CBS 14235 (MycoBank MB859328). Notably, Sp. cesarfonsecae demonstrated the ability to produce ethanol and xylitol from d -xylose, a biotechnologically valuable trait.

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.
