Abstract: Core sampling is enabled over a wide range of areas of the seabed. The present device is provided with a main robot that is moved underwater by remote operation, and a sampling robot that is connected to a manipulator that is attached to the main robot, and that can move in relation to the seabed. The sampling robot is provided with a core tube for excavating the seabed by being rotated and propelled, introducing into the core tube a core of the seabed by the excavation, and breaking the introduced core into core pieces. The main robot is provided with a core rack for storing the core pieces taken from inside the core tube.

Abstract: Disclosed is a glyceroglycolipid lipase which is highly safe, can hydrolyze a neutral fat, a glycerophospholipid or a glyceroglycolipid at about pH 6, is thermally stable to some extent, can hydrolyze lecithin, cannot hydrolyze lysolecithin, can rise a bread when used singly in the production of the bread, and has no unpleasant odor. Specifically disclosed is a glyceroglycolipid lipase derived from a filamentous bacterium Aspergillus japonicus.

Abstract: A phospholipase C enzyme having the ability to hydrolyze a phospholipid in both acidic and around neutral ranges and in a citrate buffer solution, as well as having a degree of heat stability, and having a property not to hydrolyze phosphate esters not containing lipid moieties. The phospholipase C enzyme shows activity from acidic to neutral pH and does not substantially hydrolyze any phosphate esters except for phospholipids.
