  • Patent number: 11459445
    Abstract: The present invention provides a composition capable of reducing adhesion of biofilms and therefore useful for producing a molded body. The composition comprises at least one resin (A) selected from the group consisting of thermoplastic resins and thermosetting resins, and a quorum sensing inhibitor (B), and is configured such that a common logarithm log S of solubility of the quorum sensing inhibitor (B) in water of 25° C. is less than 0.1, and Ra1 is greater than 3.2 MPa1/2, provided that Ra1 is a distance between a Hansen solubility parameter of the at least one resin (A) selected from the group consisting of thermoplastic resins and thermosetting resins and a Hansen solubility parameter of the quorum sensing inhibitor (B).

  • Patent number: 10526223
    Abstract: A method for producing a microbiologic agent is described. The method includes a step of adding biomass containing a target compound-degrading microorganism and an inorganic microparticle carrier to a medium containing a target compound. The microorganisms included in the biomass are carried on the inorganic microparticles, and the medium is cultured while monitoring an abundance ratio of the target compound-degrading microorganism in microorganisms carried on the inorganic microparticle carrier. After the abundance ratio of the target compound-degrading microorganism reaches a predetermined value, the inorganic microparticle carrier carrying the target compound-degrading microorganism is collected to obtain the microbiologic agent.

  • Patent number: 6780633
    Abstract: A method for producing from one of the optical isomers (optical isomer I) of an amino acid represented by Formula (1):R—CH(NH2)—COOH (1), wherein R is defined in the specification, the other of the optical isomers (optical isomer II), said method comprising reacting a biological material which has an ability of converting said one of the optical isomers (optical isomer I) to said the other of the optical isomers (optical isomer II), the isomerism being on the basis of an assymetric carbon atom to which both of an amino group and a carboxyl group are bound and said ability being not inhibited seriously by an amino acid transferase inhibitor &bgr;-chloro-D-alanine, &bgr;-chloro-L-alanine or gabaculine, with said one of the optical isomers (optical isomer I).
