Morphology of bacterial granules developed in an upflow anaerobic acid reactor
Bibliographic record
Abstract
Macro- and micro-structures of granules, developed in an upflow anaerobic acid reactor, were examined by light and electron microscopy. Every granule was found to be white, soft and non-spherical and had an open cavity at the centre. Scanning electron microscopy showed that the granules were composed of rod-shaped bacteria, of different thicknesses and lengths, arranged in three distinct layers within the granules. Transmission electron microscopic analysis of ultra-thin sections of granules, stained with Ruthenium Red, revealed the presence of extra-cellular polymeric materials around the cells. Gram staining tests confirmed the presence of both Gram-positive and Gram-negative bacteria in the granules. The intertwined nature of the bacterial arrangement in the granules and the extracellular polymeric substance that encapsulated the cell colonies contributed to the structural stability of the granules.

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.
