Ushbu tadqiqot ishida oqova suvlarni mikroo‘tlar yordamida fitoremediatsiya usulida tozalash hamda hosil bo‘lgan biomassadan akvakultura sohasida qiymatli bio-yem sifatida foydalanish imkoniyatlari o‘rganildi. Tajriba davomida Chlorella vulgaris mikroo‘t shtammidan foydalanilib, oqova suv tarkibidagi azot va fosfor birikmalarining o‘zlashtirilish dinamikasi hamda biomassa to‘planish ko‘rsatkichlari tahlil qilindi. Tadqiqot natijalariga ko‘ra, 10 kunlik kultivatsiya davomida oqova suvdagi azot birikmalari 82% ga, fosfatlar esa 78% ga kamayishi va suvning chuqur biofiltratsiyalanishi kuzatildi. Olingan biomassaning biokimyoviy tahlili undagi xom oqsil (crude protein) miqdori 46% ni tashkil etishini ko‘rsatdi. Olingan natijalar Chlorella vulgaris biomassasidan baliqchilikda an’anaviy ozuqa komponentlarining o‘rnini bosuvchi yuqori oziqaviy qiymatga ega bio-qo‘shimcha sifatida foydalanishning ilmiy va amaliy samaradorligini isbotlaydi.
