Özet
This study aims to investigate the effects of two different Fe forms (Fe+2 and Fe+3) and different amounts of EDTA on the growth parameters of Spirulina platensis. During the experimental period (15 day), optical density, pH, dry weight (g L-1), chlorophyll a (mu g mL(-1)) and phycocyanin concentration (mu g mL(-1)) were measured on daily basis. The chlorophyll a amount of 18.30 mu g mL(-1) was determined for the group containing 0.3mM Fe+3 with EDTA and 17.17 mu g mL(-1) chlorophyll a content was obtained from the group containing 0.3mM Fe+2 with EDTA. Phycocyanin content was found 73.42 mu g mL(-1) for the group containing 0.3mM Fe+2 with EDTA, 62.13 mu g mL(-1) for control group, and 56.75 mu g mL(-1) was found for the group containing 0.3mM Fe+3 with EDTA. According to these results, Fe+3 and Fe+2 forms were found to be more effective in presence of EDTA on the growth of S. platensis.
