Abstract

This study conducted a series of experiments to investigate the degradation performance and mechanism of chlorpyrifos (CPF) degradation by Shewanella oneidensis MR-1 (S. oneidensis MR-1). The results showed that the S. oneidensis MR-1 degradation CPF rate was maximized at a salinity of 10 g·L⁻¹, 35 °C, pH 7, and an inoculum amount of 20 %. The simultaneous addition of anthraquinone sodium 2,6-disulfonate (AQDS) and goethite [FeO(OH)] were able to increase the degradation efficiency to 174.12 %. Further, SEM results showed the FeO(OH) surface might provide a dense reaction site for the degradation. XRD and FTIR analysis revealed the hydroxyl group participated in the degradation process. XPS analysis showed that the addition of AQDS and FeO(OH) promoted the conversion of Fe(III) to enhance the degradation of CPF. Meanwhile, metabolites analysis, indicated that S. oneidensis MR-1 regulated its antioxidant capacity by enhancing its amino acid metabolism and lipid biosynthesis to cope with CPF stress. This work could provide new insights for efficient CPF removal in the future.

Shewanella oneidensis MR-1 对毒死蜱的降解：特征和机理分析

本研究通过一系列实验研究了Shewanella oneidensis MR-1 （S. oneidensis MR-1）降解毒死蜱（CPF）的性能和机理。结果表明，在盐度为 10 g-L-1、温度为 35 °C、pH 值为 7、接种量为 20 % 的条件下，S. oneidensis MR-1 降解 CPF 的速率最大。同时添加 2,6-二磺酸蒽醌钠（AQDS）和鹅卵石[FeO(OH)]可将降解效率提高到 174.12%。此外，SEM 结果表明，FeO(OH) 表面可能为降解提供了一个致密的反应位点。XRD 和 FTIR 分析表明羟基参与了降解过程。XPS 分析表明，AQDS 和 FeO(OH) 的加入促进了 Fe(III) 的转化，从而增强了 CPF 的降解。同时，代谢物分析表明，S. oneidensis MR-1 通过增强氨基酸代谢和脂质生物合成来调节其抗氧化能力，以应对 CPF 胁迫。这项研究为今后高效去除氯化石蜡提供了新的思路。
