Özet
Being active in a number of biological events, iron (Fe) is essential trace metal, which is vital for a great many organisms. In an effort to find out a biological approach to the functions of Fe, which are not yet fully understood, and its available marine forms as well as to help determine the factors affecting Fe uptake, the effects of artificial ligand EDTA (Ethylenediaminetetraacetate) (100 mu M) on the growth of Thalassiosira weissflogii were studied in modified F/2 medium consisting of 10nM iron. An ambient temperature of 18 +/- 2 degrees C and lighting intensity of 80 mu mol m(-2) s(-1) were provided during the experiment. Sea water used macro nutrients and EDTA were let through Chelex-100 resin while all other items were freed from any trace metals in acid bath. Acording to the results, it was found that in T. weissflogii culture, EDTA didn't have any effect on cell number, the number of chl-a, growth rate and the pH values which increased proportional to the growth (p>0.05). It was also appeared to be a difference among cell Fe quota (p<0.05).
