Özet

Amaç: Mevcut çalışmanın amacı bazı inorganik besin ve ağır metallerin uzaklaştırılmasında iki mikroalg suşunun-Chlorella vulgaris ve Scenedesmus sp- etkinliğini değerlendirmektir.Metod: Bu amaç için, kontrollü laboratuar koşullarında yetiştirilen yeşil mikroalgler (Chlorophyta), Fosfat 0.1-1 mM; Nitrat 5-30 mM; Ağır metaller 2,5-100 ppm'lik sulu çözeltilerde 6 farklı konsantrasyonda hazırlanan Antimon (Sb+3), Mangan (Mn+2), Bakır (Cu+2), Nikel (Ni+2), Fosfat ve nitratın (NO3-) gideriminde biyosorbent olarak kullanılmıştır. Ayrıca, 24 saatlik deney süresince ağır metal ve nutrientlerin hücrelerin total karbonhidrat ve klorofil a-b içeriği üzerine etkisi araştırılmıştır.Bulgular: Analiz sonuçlarına göre, C. vulgaris bioması tarafından fosfat, nitrat, antimon, mangan, bakır ve nikelin giderim verimliliği sırasıyla %95.91, %21.63, %28.64, %49.41, %33.38 and %29.96 olarak belirlenirken Scenedesmus sp. hücrelerinde %98.15, %14.28, %10.05, %8.52, %30.18 and %20.62 olarak belirlenmiştir. Bununla birlikte, Sb+3, Mn+2, Cu+2, Ni+2, PO4-3 ve NO3- iyonlarının C. vulgaris bioması tarafından ortalama adsorbsiyon kapasitesi sırasıyla 0.18, 0.38, 0.28, 0.15, 1.18 ve 9.30 mg g-1 ve Scenedesmus sp. bioması tarafından 2.99, 0.96, 11.50, 11.33, 0.75 ve 4.56 mg g-1 olarak saptanmıştır.Sonuç: Çalışmanın sonucunda Chlorella vulgaris ve Scenedesmus sp. nin laboratuvar şartlarında aşırı nutrient ve ağır metal giderimi üzerinde olağanüstü bir yeteneğinin olduğunun kabul göreceğini düşündürmektedir.
