In recent years, the photosynthesis microorganisms which produces the oil were found as the new biofuel. It can generate oxygen higher than plants, so it has expected as an oxygen supplier. It is usual that the aeration and impeller stirring are applied industrially as a culture mixing method for microorganisms, but in such flow systems, the shearing force promoting the mixing reaction is not uniform and the locally high shear region is occurred. So, there is concern that the cells of the photosynthesis microorganisms are destroyed. In this study, a cultivation experiment is performed using the Taylor Vortex Flow (TVF) which can be expected as loosing mixed stirring with low shearing flow. Then, the amount of alga multiplication and destruction by crushing the cells mechanically in homogenizer is observed in the experiment.
