Title:
CULTURE METHOD AND APPARATUS FOR MICROALGAE
Document Type and Number:
Japanese Patent JP2019071867
Kind Code:
A
Abstract:
To provide methods and apparatus for culturing microalgae capable of stable and efficient continuous culture of microalgae with reduced construction cost and power cost.SOLUTION: The present invention provides a method for culturing microalgae by filling a microalgal suspension on a shallow flat surface and irradiating the same with the sunlight in the daytime, while containing the microalgal suspension in an upper closed water tank and keeping the microalgal suspension in an anaerobic state in the night, the value of the volume of the upper closed water tank (cubic meter)/the sunlight irradiation area of the flat surface (square meter) being set so that the water temperature of the microalgal suspension does not exceed 40°C, and the method featuring that one part of the microalgal suspension is moved to the flat surface in the daytime and then the microalgae are cultured while the microalgal suspension in the flat surface is replaced with the microalgal suspension in the upper closed water tank.SELECTED DRAWING: Figure 6
