Abstract BACKGROUND To address the severe health risks posed by aflatoxin B 1 (AFB ) in grain, this study employed polydopamine‐based atom transfer radical polymerization (p‐ATRP) and cytochrome C‐catalyzed (c‐ATRP) as cytocompatible modification techniques to coat surface of living Lactobacillus plantarum (LAB) cells with temperature‐sensitive polymer poly( N ‐isopropylacrylamide) (PNIPAAm). RESULTS Two novel bioadsorbents were synthesized. The incorporation PNIPAAm an ‘AFB vacuum cleaner’ layer significantly enhances LAB's adsorption efficiency enables temperature‐controlled desorption. Compared p‐ATRP, c‐ATRP uses C (from membrane protein) a biocatalyst replace necessary copper catalyst eliminating risk toxicity pollution. exceptional AFB capabilities LAB@PNIPAAm can be precisely modeled using Lagergren pseudo‐second‐order Freundlich frameworks, capacity attaining 74.88 ng mL −1 . Furthermore, displays unique temperature‐responsive properties, achieving 78% at 22 °C desorption rate 69% upon temperature elevation 37 °C. It is noteworthy that technology also stress resistance LAB. CONCLUSION These findings offer insights into engineering viable bacterial efficient bioremediation multiple pollutants complex environments. © 2025 Society Chemical Industry.
