Research (English)

SeedBank Inc. Co., Ltd. supports the research related to microalgae from the very fundamental, by focusing on the technologies of 3 keywords: Isolation, Culturing, and Conservation.

Isolation: Technologies to isolate diatoms, green alga, brown alga, and almost every species of microalgae.

Culturing: Technologies for culturing the isolated microalgae species in both laboratory and industrial scales.

Conservation: Technologies to conserve isolated species semi-permanently, by artificially inducing rest spore formation.


By elucidating the physiology and dynamics of the microalgae, we are trying our best to discover useful species and to design recipes for agriculture, industrial and environmental purposes.


Applications & Developments


Feed for Fisheries


One of our key enterprises is the development of fisheries feeds. It is well-known that high-value fisheries species such as bivalves and crustaceans feed on diatoms. Some of these species rely on specific diatom species, especially in their early development stages (lavare), leading to problematic situations in aquaculture. We are aiming to solve this problem by isolating, culturing and sustainably providing the most species-specific high value feeds.




Microalgae, being the biggest primary producer in the ocean, is thus the fundamental of the food pyramid. We are trying our best to develop species-specific “recipes” of microalgae for the aquaculture of high-value fisheries.




Red tides are causing massive damage to the aquaculture, killing fish and seaweeds all over the world. Although many previous studies have attempted elucidating the “trigger factors” of this environmental disaster, the progress is limited, simply because it is extremely difficult to culture single microalgae species so that their dynamics cannot be studied, which becomes more impossible to study multiple dynamics of the real red tides.

Our technologies, however, will surely improve the situation and look forward to a breakthrough on the studies of the Red tides.




The shells of the diatoms are made of silicon dioxide (i.e. glass), which makes them look very shiny and pretty. Those shiny parts are geometrically almost perfectly regulated, which is beyond any human technologies to replicate by now. One of our purposes is to understand the mechanisms of the formation of these “structures”, thus providing ideas and models for next-generation industrial materials developments and applications.
