Shinagawa Etchujima CampusGraduate School of Marine Science and Technology

The Graduate School of Marine Science and Technology has a doctoral course divided into a master's course and a doctoral course, and trains independent highly specialized professionals who open up cutting-edge fields.Furthermore, in collaboration with the Japan Fisheries Research and Education Agency, the Japan Agency for Marine-Earth Science and Technology, and the National Institute of Maritime, Port and Aviation Technology, we will further enhance education and research and improve the quality of graduate students. We are trying to

[Title of award-winning research]
marine psychrophiles Moritella sp. F1of biosurfactants on pressure characteristics of lipase from strain I.

[Details of award-winning research]
Sagami Trough Depth500 mA psychrophilic bacterium with strong lipolytic activity isolated fromMoritella sp. F1Stocks andF3The stocks are2Types of lipaseLip-I,Lip-IIThe gene sequence of the enzyme isF1Stocks and F3From the stock100%It matches, butF1The lipase from the strain is a piezophilic enzyme, whereasF3The lipases from the strains were non-piezophilic enzymes and had different pressure characteristics.F1Noting that the strain produces a large amount of biosurfactant during cultivation, this study found that adding a low concentration of biosurfactant increased barophilicity, but a high concentration had no effect on increasing barophilicity and instead reduced barotolerance.
