Pesticides play an important role in agriculture; however, their excessive use causes several problems such as pollution of ecosystems and risks to human health. The presence of microorganisms able to degrade these pollutants can reduce their negative effect. The objective of this study was to test the capacity of Weissella confusa Lb.Con to tolerate or to degrade the chlorpyrifos pesticide. The results showed the capacity of the strain to tolerate a concentration of 200 μg/ml of chlorpyrifos. The strain Lb.Con has a remarkable capacity to grow in glucose-free MRS medium which contains different concentrations of chlorpyrifos. HPLC analysis showed that this strain was able to remove about 25% of chlorpyrifos. The evaluation of some probiotic properties showed that the strain Lb.Con had a remarkable resistance to the gastrointestinal conditions and a good antibacterial activity towards the pathogenic bacteria. The probiotic potential was evaluated to verify the possible use of W. confusa Lb.Con to detoxify harmful chlorpyrifos contained in food.
农药在农业中起着重要作用；然而，它们的过度使用会导致生态系统污染和对人类健康的风险。能够降解这些污染物的微生物的存在可以减少它们的负面影响。本研究的目的是测试魏斯氏菌 Lb.Con 耐受或降解氯氰菊酯农药的能力。结果表明，该菌株能够耐受 200μg/ml 的氯氰菊酯浓度。该菌株 Lb.Con 具有在含有不同浓度氯氰菊酯的无葡萄糖 MRS 培养基中生长的显著能力。HPLC 分析表明，该菌株能够去除约 25%的氯氰菊酯。一些益生菌特性的评估表明，该菌株 Lb.Con 对胃肠道条件有很强的抵抗力，对病原菌有很好的抗菌活性。对益生菌的潜力进行了评估，以验证使用魏斯氏菌 Lb.Con 解毒食品中有害氯氰菊酯的可能性。
