مخمرهای تک سلولی بخشی از فلور روده آبزیان می باشند. تعدادی از این تک سلولی ها مفید و برخی مضر بوده و عامل تعدادی بیماری شناخته شده و ناشناخته می باشند. تاکنون هیچ مطالعه جامعی در خصوص شناسایی تنوع فلور مخمری روده ماهیان قزل آلا در ایران انجام نشده است. نظر به اهمیت شناسایی و بررسی امکان استفاده از آن ها به عنوان پروبیوتیک های بومی، ایزوله سازی و بررسی تنوع مخمرهای فلور روده ماهیان قزل آلای شهرس...
