摘要： The present invention provides a method for producing an organic acid using algal biomass, The present invention pertains to the production of organic acids such as succinic acid using Euglena , by means of a method containing; either a nitrogen deficient culture step in which Euglena is cultured. aerobically under nitrogen-deficient conditions or a heterotrophic culture step in which Euglena is cultured aerobically using a culture medium containing a carbon source; and an anaerobic culture step in which the culture product obtained in the nitrogen-deficient culture step is incubated under anaerobic conditions.

摘要： An object of the present invention is to construct a production system that enables efficient production of organic acids using blue-green algae, which are photosynthetic microorganisms, by utilizing carbon dioxide and thereby increasing an amount of organic acids produced. The present invention relates to blue-green algae overexpressing a clock protein gene and a method for producing organic acids by culturing the blue-green algae.
