| Summary, etc. | Metalaxyl (MY) is a water soluble synthetic acylanilide fungicide widely used in agriculture practices to control phytopathogenic fungi, but it elicits environmental pollution to underground water as well as human health. The safe and effective removal of agrochemical pollutants from contaminated field sites is performed by some soil and aquatic microorganisms. However, limited work has been done focusing on the intermediate metabolites’ residues produced and enzymes involved in the biodegradation process of fungicides. The degradation ability of the isolated aquatic fungus Aspergillus wentii of the MY as a sole carbon source in only sterilized distilled water was evaluated in vitro after 15 days, reaching high levels of biodegradation at 68%. Furthermore, the possible catabolic degradation pathways of MY based on the detected metabolites beside the enzymes involved in the biodegradation process were established. Moreover, a TripleTOF 5600 + LC-MS/MS was employed to identify the enzymes involved in the biodegradation process of the fungicide. The results revealed that CYP450 is responsible for metabolism of MY. It could be concluded that A. wentii enzymes have a prospective potential to eliminate a wide spectrum of toxic environmental pollutants, such as MY. To our knowledge, this study is the first report that A. wentii CYP 450 could catalyze the degradation of metalaxyl. |

| Summary, etc. | ميتالاكسيل (MY) هو مبيد فطريات أسيلانيليد اصطناعي قابل للذوبان في الماء يستخدم على نطاق واسع في الممارسات الزراعية للسيطرة على الفطريات المسببة للأمراض النباتية، ولكنه يسبب التلوث البيئي للمياه الجوفية وكذلك صحة الإنسان. تتم الإزالة الآمنة والفعالة للملوثات الكيميائية الزراعية من مواقع الحقول الملوثة بواسطة بعض الكائنات الحية الدقيقة الموجودة في التربة والماء. ومع ذلك، فقد تم إنجاز عمل محدود يركز على نواتج التكسير الحيوى للمبيدات الفطرية والإنزيمات المشاركة في عملية التحلل الحيوي. تم تقييم قدرة تحلل الفطر المائي المعزول Aspergillus wentii لمبيد الميتالاكسيلMY كمصدر وحيد للكربون في المختبر بعد 15 يومًا، حيث وصل إلى مستويات عالية من التحلل البيولوجي بنسبة 68%. علاوة على ذلك، تم اقتراح مسار التحلل الحيوي المحتمل لـ MY بجانب الإنزيمات المشاركة في عملية التحلل الحيوي. علاوة على ذلك، قدمت الدراسة دليلاً على أن الفطر يحتوي على CYP450 المسؤول عن عملية التحلل الحيوى لـ MY. يمكن أن نستنتج أن إنزيمات Aspergillus wentii لديها القدرة المحتملة على القضاء على مجموعة واسعة من الملوثات البيئية السامة، مثل MY. على حد علمنا، هذه الدراسة هي التقرير الأول الذي يفيد بأن Aspergillus wentii CYP450 يمكن أن يحفز تحلل الميتالاكسيل.<br/><br/><br/><br/><br/><br/><br/><br/> |
