Publication number: 20160194600Abstract: An object of the present invention is to provide a method for performing fluid surface-floating culture of microalgae without supplying new seed algae. Microalgae on the bottom surface are used as seed algae. That is, there is provided a method for culturing microalgae which includes: a first culture process of culturing microalgae in a medium within a culture vessel, forming a biofilm on the liquid surface of the medium, and maintaining the microalgae on the bottom surface of the culture vessel; a process of collecting at least a part of the biofilm on the liquid surface formed in the first culture process and leaving at least some microalgae on the bottom surface inside the culture vessel; and a second culture process of culturing the microalgae remaining on the bottom surface within the identical culture vessel, and forming a biofilm on the liquid surface of the medium. In addition, the present invention provides novel microalgae which can form a biofilm on the liquid surface.Type: ApplicationFiled: March 18, 2016Publication date: July 7, 2016Applicant: FUJIFILM CorporationInventors: Hideyuki KANEHARA, Tadashi MATSUNAGA, Tsuyoshi TANAKA, Masayoshi TANAKA, Masaki MUTO

Publication number: 20160194671Abstract: In a liquid surface-floating culture method in which culturing of microalgae is performed on the liquid surface, there is provided a culture method in which the oil content in microalgae is improved. In addition, there is a provided a method for decreasing the probability of recovery of bottom surface algae. Furthermore, an object of the present invention is to provide a culture method in which the proliferation rate of microalgae is improved. Culturing is performed such that a medium is suctioned from a region, in which there is a small quantity of microalgae between the liquid surface and the bottom surface, is discarded, and is replaced with a medium of which the concentration of a nitrogen compound or a phosphorus compound is lower than that of the above-described medium. In addition, a liquid is added thereto immediately before collecting microalgae on the liquid surface, and the water depth in a culture vessel is made to be deep.Type: ApplicationFiled: March 18, 2016Publication date: July 7, 2016Applicant: FUJIFILM CorporationInventors: Hideyuki KANEHARA, Tadashi MATSUNAGA, Tsuyoshi TANAKA, Masayoshi TANAKA, Masaki MUTO
