Oxidative stress response of Acinetobacter lwoffii DNS32 exposed to atrazine-contaminated
Bibliographic record
Abstract
To investigate the oxidative stress response of antioxidant enzymes in atrazinedegrading bacterium exposed to atrazine played a significant role in the application of bacterium. A. lwoffii DNS32 and S. aureus R2 cultures were treated with different concentrations of atrazine. After exposure to atrazine for 0, 6, 12 and 24 h, bacterial cells were harvested in order to assay SOD, CAT, GST activities and T-AOC. The results showed that at 6 h T-AOC was induced, and the biggest inducement rate of SOD, CAT and GST activities were 111.26% and 55.47%, 72.79% and 61.61%, 33.35% and 52.76% in the two bacteria, respectively. At 24 h SOD and CAT in A. lwoffii DNS32 were induced, and GST and T-AOC were inhibited. But SOD, CAT, GST activities and T-AOC in S. aureus R2 were inhibited at 24 h. Compared with S. aureus R2, A. lwoffii DNS32 had relatively high tolerance to atrazine stress.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
