Özet
The Cu (II), Cd (II) and Cu (II) + Cd (II) ions bioaccumulation properties of Chlorella vulgaris were investigated using a batch culture as a function of in the presence/absence of EDTA and the mean growth was observed timely for 96 hours. Growth parameters of Chlorella vulgaris which are cell density, chlorophyll-a, dry-wet weight and pH values were determined for 96 hours. While the highest cell density (828.20±4.095 × 104 cell mL-1), chl a (0.42±0.017 ?g mL-1), dry weight (0.54±0.008 g L-1) and pH (10.35±0.028) were found in control group, the lowest cell density (185.89±4.509 × 10 4 cell mL-1), chl a (0.16±0.046a ?g mL -1) was in the fifth group, dry weight (0.07±0.011g L -1) in 30th and pH (5.57±0.054) in second group were found in all treatments on 24th and 48th hour of the study. Results indicated that algal growth and metal toxicity of C. vulgaris were significantly affected by the presence of EDTA, metal compounds of copper (Cu) and cadmium (Cd).
