This paper describes a biocatalyst culture environment in a photosynthetic bioreactor. Generally, in the cultivation of the biocatalysts, stirring is important factor for the uniform nutrient supply. A screw propeller is used for a simple agitation, however, the problem is that there exists a very high shearing flow region just near the propeller and the biocatalysts can be destructed by the shearing force. Therefore, we have attention to TVF stirring, because this means is expected to reduce such a local and random shearing force. In this study, for the investigating of the relationship between the photosynthetic biocatalysts growth rate and the flow structures in a concentric rotating cylinders type cultivation container, the flow structures in the container were measured by an ultrasonic velocity profiler (UVP).
