Extensive use of pyrethroid insecticides poses significant risks to both ecological ecosystems and human beings. Herein, Pseudomonas aeruginosa PAO1 exhibited exceptional degradation capabilities towards a range of pyrethroid family insecticides including etofenprox, bifenthrin, tetramethrin, D-cypermethrin, allethrin, and permethrin, with a degradation efficiency reaching over 84 % within 36 h (50 mg·L). Strain PAO1 demonstrated effective soil bioremediation by removing etofenprox across different concentrations (25-100 mg·kg), with a degradation efficiency over 77 % within 15 days.

Article Synopsis
  • Chlorpyrifos contamination poses significant environmental challenges, necessitating the development of effective removal techniques.
  • A strain of Pseudomonas nitroreducens W-7 shows exceptional ability to degrade both chlorpyrifos and its main metabolite, significantly reducing their toxicity and demonstrating effective soil bioremediation by eliminating over 50% of chlorpyrifos in just 5 days.
  • The enzyme Oph2876, identified in W-7, plays a key role in the degradation process, showing unique characteristics and highlighting critical amino acids essential for its activity, thus contributing to future strategies for chlorpyrifos bioremediation.

Insect Defense Laboratory, Molecular Biology, and Biotechnology Division, Council of Scientific and Industrial Research (CSIR)-National Botanical Research Institute (NBRI), 435 Rana Pratap Marg, Lucknow, Uttar Pradesh 226001, India.

Lytic polysaccharide monooxygenases (LPMOs) are powerful redox enzymes that transform complex carbohydrates through oxidation and make them suitable for saccharification by canonical hydrolases. Due to this property, LPMOs are considered to be a valuable component of enzymatic consortia for industrial biorefineries. Tma12 is a fern entomotoxic protein that kills whitefly and has structural similarities with chitinolytic LPMO.
