Abstract: An object of the present invention is to provide a soft biomass decomposition method, a production method for a target substance from soft biomass, and an enzyme or group of enzymes for decomposing soft biomass. Provided is a soft biomass decomposition method, including a step of bringing an enzyme selected from specific exocellulase, endocellulase, and processive endocellulase into contact with soft biomass such as bagasse and rice straw. Also provided is a production method for a target substance from soft biomass by incorporating the soft biomass decomposition method as a step. Further provided is an enzyme or group of enzymes for decomposing soft biomass selected from specific exocellulase, endocellulase, and processive endocellulase.

Abstract: Provided is an antibody production method whereby it is possible to repeatedly acquire antibodies produced by fish without killing the fish. Specifically provided is an antibody production method whereby it is possible to repeatedly acquire the antibodies produced by a fish, without killing the fish, by administering antigens to fish that have blisters.

Abstract: It is an object of the invention to provide a method and an apparatus for processing a very large number of fish eggs for gene injection and so on with a superior performance. An egg case has an egg-arranging plate and a cover plate. The fish eggs are dropped into concave portions of the egg-arranging plate, when the cover plate opens the concave portions. The cover plates closes the concave portions after fish eggs are accommodated in the concave portions. The egg case is fixed on a table of an egg-arranging apparatus. water is supplied on the egg-arranging plate in the egg plate. A scanning nozzle sprays water on upper surface of the egg-arranging plate. After closing the concave portions with the cover plate, the egg case is inclined for dropping fish eggs remaining on the cover plate.

Abstract: It is an object of the invention to provide a method for processing a very large number of fish eggs for gene injection and so on, which employs a simple system with high performance and a reasonable construction expense. It is another object to provide the method having an water tank apparatus capable of producing a large number of fish eggs continuously. A large number of water tank groups having an independent drainage passage each is lighted up in turn with a predetermined interval. An egg-collecting case with a net bottom is set in the drainage passage connecting to the water tank group to which the lighting is started. The water tank group consists of a plurality of tank unit accommodating fishes each. Each book-shaped tank unit has a rectangular-shaped upper portion and a cone-shaped lower portion. Rotating water stream is formed in each tank unit.

Abstract: Disclosed is a discussion of a method for producing anti-mammalian GPCR antibody and of the antibody itself. Anti-mammalian GPCR antibody is produced through immunization involving exposure of fish to full-length or truncated mammalian GPCR, and anti-mammalian GPCR antibody that can be obtained by this method is also discussed.

Abstract: A fertilized eggs collection apparatus for injecting genes, which is superior in safety and productivity. It is realized by simple structure. Fertilized eggs are collected from drainage with the fertilized egg in a water tank. The collection is synchronized for starting of illumination to the water tank. A probability that that feces included in the water is mixed in the collected fertilized eggs can hereby be reduced. Water including the fertilized eggs is accumulated on a fertilized-egg-holding-plate. The fertilized-egg-holding-plate has each concave portion holding one fertilized egg each. Water in the concave portions is drained from a through-hole. The fertilized-egg-holding-plate is accommodated in a case having a bottom plate portion. The case keeps water for the fertilized eggs. A shutter plate capable of sliding is disposed on the fertilized-egg-holding-plate. The shutter plate prevents that the fertilized eggs jump out from the concave portions of the fertilized-egg-holding-plate.
