Growth kinetics of Cylindrotheca closterium (Ehrenberg) Reimann and Lewin isolated from aegean sea coastal water (Izmir Bay/Türkiye)

The aim of this research was to reveal the detailed information on growth kinetics of Cylindrotheca closterium (Ehrenberg) Remann and Lewin from the results of nutrient enrichment experiments under batch culture conditions. C. closterium was isolated from Izmir Bay. The present study were performed under optimum light and nutrient saturated conditions except the nutrient, which was investigated. An exponential growth rate was obtained by using each growth curves. The exponential growth rates were plotted against corresponding each nutrient concentrations. The parameters of Monod curve were calculated with the least square method by using transformations to linear form. Half Saturation Constant (Ks) was calculated for only silicate as 9.58 µM maximum growth rate were found as 4.32 day -1 . © 2006 Asian Network for Scientific Information
