Abstract: (2200 Views)
In the present study, the effect of different concentrations of hormone ethinyl estradiol was investigated on microalgae Cheatoceros muelleri. Seven different concentrations (250, 500, 1000, 1500, 1750, 2000, and 2500 μg/l) of the hormone were measured by a replicate control treatment. Factors including the size of chlorophyll a, specific growth coefficient, and protein content were measured in microalgae C. muelleri. The results showed that at concentrations of 250 and 500 μg/l, growth rate and chlorophyll a content in hormone-treated samples increased significantly compared to the control. In contrast, more protein was observed at the concentration of 250 μg/l than in the control group in microalgae. The results of this study showed that increasing the treatment period in most concentrations had a significant effect on growth inhibition and in some cases caused the growth of microalgae. Higher concentrations of the hormone also affected the growth inhibition, chlorophyll amount, and protein contents of C. muelleri.
