Temperature Dependence of Population Growth in a Green Microalga: Thermodynamic Characteristics of Growth Intensity and the Influence of Cell Concentration
نویسندگان
چکیده
Growth intensity o f the green alga, Scenedesmus obliquus, was measured in autotrophic cultures, diluted once daily, between 20 and 30 °C in a light-dark cycle o f 16 : 8 h at initial optical densities between 0.02 and 1.2. Arrhenius analyses o f the results showed linear relationships be tween growth intensity and temperature below the temperature optimum. The temperature effects on growth, activation energy, deactivation energy and normalized Q i0 values were signifi cantly influenced by the amount o f available light energy per unit biomass. The temperature dependence o f nutrient-limited growth was not considered.
