Abstract

fetched live from OpenAlex

The effect of xylitol on the growth of Streptococcus mutans LG-1 was investigated under various conditions. Concentrations of xylitol ranging from 0.5 to 2% increased the time usually needed by the cells to reach the stationary phase in the presence of 0.2% glucose, mannose, lactose, mannitol, or sorbitol. Xylitol had no effect in the presence of fructose or sucrose. The xylitol-mediated inhibition was not modified by temperature or pH variations or by the presence or absence of oxygen. Repeated culturing in the presence of xylitol plus one of the above-mentioned sugars enabled the bacterium to tolerate the presence of xylitol. The cells, however, were still unable to grow at the expense of xylitol. The results indicate that this adaptive process arose from a mutational event.

Full frame distilled prediction

Teacher imitation

Not 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.
