الملخص

   تعد ملوثات الجسيمات البلاستيكية الدقيقة (MPs) مصدر قلق متزايد على مستوى العالم، ويتم التحقيق في طرق مختلفة لتقليلها. هدفت هذه الدراسة إلى تقييم قدرة البكتيريا المعزولة من خزان الغسيل في مصنع أنابيب البولي فينيل كلوريد (PVC)  على تحلل الجسيمات البلاستيكية الدقيقة. على مدى 60 يومًا، تم حضن البكتيريا المعزولة مع قطع البلاستيك في وسط أملاح معدنية. تم تحديد هذه السلالات على أنها Aeromonas hyrophila (B1) Shouchella clause (B2), Staphylococcus hominis (B3), . Bacillus sporothermodurans (B4), لتحديد تحلل البلاستيك الدقيق من البولي فينيل كلوريد (Micro-PVC plastic) بعد الحضانة، تم اختيار ثلاث طرق: تحليل الأشعة تحت الحمراء بتحويل فورييه (FTIR) ، وتحليل كروماتوغرافيا الغاز والكتلة الطيفية (GC-MS) ، وتجارب فقدان الوزن. أظهر تحليل FTIR تغيرات في القمم، مما يشير إلى تمدد، وثني، وتكوين روابط جديدة في البلاستيك المعالج مقارنةً بعينة السيطرة. كشف تحليل GC-MS عن تكوين حمض كربوكسيلي وبعض المركبات الجديدة خلال تحلل البلاستيك الدقيق Micro-PVC. كانت نتائج تجربة فقدان الوزن للسلالات الميكروبية B1، B2، B3، B4، والأتحاد الميكروبي (MC) هي 13%، 18.3%، 21.7%، 8.3% و33.3% على التوالي. تم تحضير MC بدمج جميع العزلات البكتيرية الأربعة. في هذه الدراسة، أظهرت سلالات الأتحاد البكتيري معدل تحلل عالي للبلاستيك الدقيق Micro-PVC. يمكن أن تقوم هذه الاجناس من البكتريا بتحلل البلاستيك بيولوجياً في الطبيعة، مما يجعلها أساسًا مثاليًا للقضاء على الملوثات الصعبة.
