The lab studies how microorganisms live in the sea and aims to put their abilities to use in areas such as energy.

The Marine Microbiology Lab aims to understand how microorganisms living in marine environments live (their physiology and ecology) and to carry out applied research that makes use of their characteristics. The lab works on applying marine microorganisms to the production of clean energy and the degradation of plastics. The lab also investigates the physiology, ecology, and diversity of microorganisms living in a variety of marine environments, and searches for microorganisms that reduce nitrous oxide, a greenhouse gas.

The lab works to prevent diseases of fish and shellfish, aiming for safe seafood and sustainable aquaculture and stock enhancement.

Professor Hisae Kasai's lab studies diseases of fish and shellfish and the safety of seafood from a microbiological perspective. In the seed production of fish and shellfish (hatchery rearing of juveniles), diseases caused by protozoa, fungi, bacteria, viruses, and other agents occur, and they greatly affect the results of later stocking and aquaculture. The lab carries out basic research that investigates how these diseases arise, and applied research that uses that knowledge to control the diseases. As a Reference Laboratory of the World Organisation for Animal Health (OIE) for viral diseases of salmonids, the lab also works on developing diagnostic methods and disease control measures.

A lab that uncovers the molecular structures of marine organisms using cryo-electron microscopy.

Associate Professor Takeshi Yokoyama uses cryo-electron microscopy to determine the structures of biomolecules derived from marine organisms. Cryo-electron microscopy is a method in which biomolecules are rapidly frozen, trapped in a thin film of glass-like ice, and observed directly with a transmission electron microscope. The lab focuses on ribosome complexes and works on the structural analysis of a variety of biomacromolecular complexes. Samples are prepared in the lab, data are collected at cryo-electron microscopy facilities across Japan, and structural analysis and biochemical functional analysis are then carried out in the lab.

A lab that uncovers, from the level of proteins, how the muscles of jellyfish and shellfish work.

Assistant Professor Hiroyuki Tanaka studies proteins that function inside the cells of aquatic animals, aiming to clarify the mechanisms of biological phenomena and functions at the molecular level. Marine organisms have evolved their body forms and ecology to live in environments very different from those on land, such as low temperatures, high water pressure, and high salinity. Muscle, the organ of movement, also has unique features, and recently the lab has been focusing on the muscle proteins of cnidarians, represented by jellyfish.
