METHOD FOR COLLECTING SEED ALGAE FROM MICROALGAE ON LIQUID SURFACE, AND FOR PERFORMING CULTURING IN SEPARATE CULTURE VESSEL, IN METHOD FOR CULTURING MICROALGAE ON LIQUID SURFACE
Provided is a method of culturing microalgae which can reduce the production cost of biomass derived from microalgae. There is provided a method of culturing microalgae, including: culturing in a first stage in which microalgae obtained through a purification process are cultured in a culture solution within a first culture container to form a biofilm as a film-like structure or a three-dimensional structure which is formed of the microalgae on a liquid surface of the culture solution and culturing in a second stage in which microalgae are cultured on a liquid surface using at least a part of the biofilm as a film-like structure or a three-dimensional structure which is formed on the liquid surface of the culture solution, as seed algae.
