تقييم تأثير استخدام مصدر النيتروجين مثل اليوريا ومياه غسل الأرز (RWW) على التركيب الكيميائي والأحماض الدهنية
والأحماض الأمينية للطحالب البحرية الدقيقة نانوكلوربسس أوشينيكا
يجب أن تكون وسائط تربية الطحالب المجهرية فعالة من حيث التكلفة ، وتمكن من النمو العالي ، وتفي بالمتطلبات الدقيقة وتكون متاحة بسهولة. تم تقييم تأثير المستويات المختلفة من اليوريا وماء غسيل الأرز [25 و 50 و 75٪] في وسط النمو على المكونات البيوكيميائية (البروتين والكربوهيدرات والدهون والأحماض الدهنية والأحماض الأمينية) في نانوكلوربسس أوشينيكا مقارنة مع الوسط القياسي F / 2 Guillard. أوضحت النتائج المتحصل عليها أن المكونات الكيميائية لنوع نانوكلوربسس أوشينيكا قد تأثرت بمستوى اليوريا المستخدم وماء غسيل الأرز. تم الحصول على أعلى نسبة بروتين ، ومحتويات كربوهيدرات ، وأعلى نسبة من الأحماض الأمينية الأساسية (EAA) (55.16٪) باستخدام وسط MF3 (75٪ RWW) مقارنة بالكنترول (100٪ F / 2). تم تحقيق أعلى محتوى إجمالي للدهون باستخدام وسط MF3 (75٪ RWW) ينتج (41.72٪) ، حيث تم الحصول على أعلى إنتاجية للكتلة الحيوية وإنتاجية الدهون في وسط MF3. وفقًا لذلك ، تم تسجيل أعلى نسبة إجمالي للأحماض الدهنية المشبعة (TSFA) من نانوكلوربسس أوشينيكا بواسطة وسط MF3. ومع ذلك ، تم عرض أعلى نسبة إجمالية للأحماض الدهنية غير المشبعة (USFA) بواسطة وسط MF3.
أوصت الدراسة الحالية بنتائج التربية للإستخدام في الإستزراع المائي باستخدام وسط MF3 و MF2 كمحفز للدهون وكمحفز للبروتين.
