Research Interests

Hatching of Volvox carteri

We are investigating the mechanism of growth, development and evolution of photosynthetic microorganisms. We are currently focusing on the study of the edible multicellular cyanobacterium Arthrospira (Spirulina) platensis.

Arthrospira platensis is a filamentous alkalophilic cyanobacterium that has been traditionally consumed as food by people living along the shores of alkaline lakes in several regions in the world. It is one of the most protein-rich food known, as it contains as high as approximately 60% protein in dry weight. Because Arthrospira can be cultured under alkaline conditions where growth of other microalgae is suppressed, it can be cultured outdoors as an almost single algal strain. Because of the easiness of its unialgal cultre, Arthrospira is commercially cultured in many subtropical areas in the world and consumed worldwide as food, food additives, and feed for animals and fishes. It is usually marketed with the name spirulina, which is based on its former scientific name, Spirulina. We are currently focusing on developing tools and technologies for molecular genetic study of this cyanobacterium.
