Abstract
Penicillium ramulosum N1 was isolated from decaying wood. This strain produces extracellular xylanases and cellulases. The highest activities of xylanases (250 U/ml) and carboxymethyl cellulose (CMCase; 6.5 U/ml) were produced when 1% barley straw was added as a carbon source. The optimum temperature and pH for xylanase activity was 55 and 3.0 °C, respectively. The xylanases exhibited strong protease resistance. CMCase revealed maximum activities at pH 3.0 and in the range of 60-70 °C. Filter paper activity was optimally active at pH 5.0 and 55 °C. The zymograms produced by the SDS-PAGE resolution of the crude enzymes indicated that there are four bands of protein with xylanase activity and three bands of proteins with endoglucanase. The results revealed that P. ramulosum N1 is a promising acidophilic and protease-resistant xylanase-producing microorganism that has great potential to be used in animal feed and food industry applications.

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 it
