| Popis: | 101 In this study, light indensity distribution in a cylindrical photobioreactor was examined for cultures of Tetraselmis Chui by measuring light intensity in situ in the photobioreactor. Simulation for effects of light intensity, biomass concentration and radias of cylindrical photobioreactor on growth were investigated using a Haldane growth model for cultures of Tetraselmis Chui. Major events as following： （1）Biomass concentration and radius of a cylindrical photobioreactor affect light intensity inside the reactor. It was shown that Beer’s law could be applied to the attenuation of light intensity for cultures of Tetraselmis Chui. The absorption coefficient of light intensity ε was 0.663 L / g．cm obtained from results.Light intensity was hardly affected by biomass concentration as the optical density of culture below 0.5. （2）The growth rate of Tetraselmis Chui increased with the increase in light intensity in the range from 2000 to 5000 Lux. Growth inhibition was observed as the light intensity greater than 20000 Lux. The growth rate became saturated as the light intensity close to 10000 Lux.
