In marine life science and molecular chemistry field, we research various life phenomena of microorganisms, fishes, shellfishes, and algae in marine environments at the levels of a molecule, e.g., biologically active substances, protein, and gene or genome to clarify a various kinds of physiological functions. Based on these investigations, we publish scientific and technological findings to support the development of functional foods, cosmetics, disease-preventive pharmaceuticals. In addition, these findings also contribute to the improvement of hygienic conditions in manufacturing process and increasing in the quality of healthy life.
