التفكيك الحيوي للهيدروكربونات البترولية الموجودة في تراكيز مختلفة من المازوت والغازولين باستخدام بعض الأحياء الدقيقة
Abstract
طبقت هذه الدراسة المخبرية على بعض الأحياء الدقيقة القادرة على تفكيك تراكيز مختلفة من بعض الهيدروكربونات البترولية الموجودة في المازوت والغازولين.
تم عزل بعض الأنواع البكتيرية التابعة للأجناس (Pseudomonas, Escherichia, Staphylococcus) من عينات مائية بحرية جمعت من منطقة مرفأ اللاذقية, ومصب مصفاة بانياس في البحر والتي تكيفت للحياة في هذه الأوساط لما تحتوي من المغذيات بنسب مختلفة, حيث فككت السلالات المعزولة والمنتقاة التابعة لتلك الأجناس الهيدروكربونات البترولية بنسب مختلفة تتراوح بين(2-99)%.
استخدمت تقانة مطيافية الفلورة UV- Florescence (Ultra Violent -Florescence) لتحديد التراكيز الكلية للهيدروكربونية البترولية خاصة الفحوم الهيدروجينية متعددة الحلقات العطرية ال Poly Cyclic Aromatic Hydrocarbons الـ(PAHS).
This laboratory research has been carried out on some microorganisms capable of degrading poly-aromatic hydrocarbons in various concentrations of (DiezelOil,Gzoline).
Some bacteria strains that belong to (Pseudomonas, Escherichia, Staphylococcus) were isolated from water samples collected from Lattakia port and discharge point of Banias refinery sewage line, which adapted to live in these media because of the nutrients.
Strains which belong to those genus were degraded petroleum hydrocarbons in various property between (2-99)%.
We used UV-F (Ultraviolet -Florescence) to determine the total Petroleum hydrocarbons compounds and poly aromatic hydrocarbons in particular.
