Abstract

fetched live from OpenAlex

Miliusa velutina (MV) antioxidants are being used for food or medical purposes, However, the use of the plant is limited since some Miliusa genus are endangered or critically endangered species. This study aims to find the MV endophytic bacteria that can produce the antioxidants (total phenol content (TPC), total flavonoid content (TFC), total antioxidant capacity (TAC), reducing power (RP); and ferric reducing antioxidative power (FRAP)) and their optimum fermentation condition by utilizing morphology, SEM, 16S rRNA, and CCD model. Results found that 44 endophytic bacterial strains isolated from various parts of the plant showed promising antioxidative activities, with the highest produced by Pantoea sp. MV-R3. The model indicated that 15.41 g/L of glucose in pH 7.72 at 29.19 °C for 46.54 h was the optimal fermentation condition. The maximal activities reached 89.1 % to 129.0 % compared with the predictions. The activities of TPC, TFC, TAC, RP, and FRAP were 41.54 ± 7.69, 33.18 ± 4.55, 207.36 ± 30.89, 119.55 ± 14.34, and 57.02 ± 9.15 mg per mL, respectively. Hence, the MV endophyte and its optimum fermentation condition were successfully identified.

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.
