Abstract

fetched live from OpenAlex

Monocrotophos (dimethyl (E)-1-methyl-2-(methylcarbamoyl) vinyl phosphate, or MCP), an organophosphorus insecticide, was used as a sole phosphorus source by the microorganisms isolated from the soil. None of the isolates could utilize MCP as a sole source of carbon. Two of the potential microbial isolates, Pseudomonas aeruginosa F10B and Clavibacter michiganense subsp. insidiosum SBL 11, could utilize MCP as a sole source of phosphorus. Pseudomonas aeruginosa F10B showed a lag phase of 4 h, while in the case of C. michiganense subsp. insidiosum SBL 11, it was 8 h when cultured in the presence of MCP. The generation time for both strains was increased in the medium containing MCP. It was 2.15 h for P. aeruginosa F10B in MCP medium as compared with 1.29 h in basal medium, while in case of C. michiganense subsp. insidiosum SBL 11 it was increased to 3.4 h in MCP medium as compared with 1.28 h in basal medium. These two strains were able to degrade technical MCP in shake-flask culture up to 98.9 and 86.9%, respectively, and pure MCP up to 79 and 80%, respectively, within 24 h at 37 degrees C. The optimal concentration of MCP required for the normal growth was 500 ppm. In the substrate preference study, Tris-p-nitrophenyl phosphate was the most preferred substrate followed by paraoxon. The enzyme responsible for the break down of MCP was phosphotriesterase, which was localized on the membrane-bound fraction of the disrupted cells. The gene responsible for the production of phosphotriesterase (opd) in P. aeruginosa F10B was plasmid-borne.

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.
