  • Patent number: 8080402
    Abstract: The present invention relates to a method for expressing each of peptide antibiotics P5 3 and Anal3 35 having amphiphilicity and showing antibacterial, antifungal and anticancer activities 61, 63, 65, 67, 69, 71, on the microbial surface, using a vector containing outer membrane protein genes (pgsBCA) that are derived from Bacillus sp. strains and involved in the synthesis of poly-gamma-glutamate. Moreover, the present invention relates to lactic acid-forming bacteria having each of the peptide antibiotics P5 15 and Anal3 43 expressed on their surface, and the use thereof. According to the present invention, the peptide antibiotics can be expressed on the surface of various microorganisms transformed with the surface expression vectors. The inventive method for the surface expression of the peptide antibiotics allows the peptide antibiotics to be mass-produced without a purification process. Thus, the inventive method has very high industrial applicability.

  • Patent number: 7679867
    Abstract: A magnetic flux coupling-type superconducting current limiter is capable of protecting lines more effectively by winding reactors of a primary coil and a secondary coil in series in the structure where the primary coil and the secondary coils are wound in parallel in the conventional magnetic flux-lock type current limiter to increase a linked flux generated from an iron core. An electric conducting current which rapidly increases when a fault occurs is divided into the secondary coil and a superconducting coil to decrease a load on the superconducting element and it is opened more rapidly than the existing superconducting current limiter during a quench time such that it better limits a fault current.
