  • Method for photoculturing and harvesting microalgae
    Patent number: 9222065
    Abstract: The present invention relates to a method for photoculturing and harvesting microalgae, and more particularly to a method for photoculturing and harvesting microalgae, in which a light emitting diode (LED) is used as a light source to increase the efficiency with which microalgae are cultured, and the cultured microalgae are harvested using a natural polymer flocculant and air microbubbles so that the operating cost is reduced and the range of application of microalgae is expanded, and also a semi-continuous culture method is applied so that the maximum concentration of microalgae can be produced again within a short time, even though the amount of microalgae harvested is small.
