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 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.
