  • Publication number: 20070105150
    Abstract: The present invention relates to an expression vector which can effectively express target proteins or peptides on the surface of cells using an outer membrane protein (FadL) of E. coli as a surface anchoring motif. Also, the present invention relates to microorganisms transformed with the expression vector, and a method for stably expressing large amounts of target proteins on the surface of cells by culturing the transformed microorganisms. Furthermore, the present invention relates to a production method of protein arrays, a production method of antibodies, and a bioconversion method, the methods being characterized by using target proteins which have been expressed on the cell surface by the inventive method. In addition, the present invention relates to a method for improving target proteins by the inventive surface expression method. The present invention allows target proteins with normal functions to be expressed on an outer cell membrane.

  • Publication number: 20060293433
    Abstract: Provided are a polymer resin composition and a method of preparing the same. The polymer resin composition includes: a polymer resin; 0.01-10.0 parts by weight of flaky pigment particles having an aspect ratio of 0.01-0.1 based on 100 parts by weight of the polymer resin; and 0.01-10.0 parts by weight of polyhedral pigment particles having an aspect ratio of 0.300-0.999 based on 100 parts by weight of the polymer resin. Using the polymer resin composition, a polymer resin molded product having excellent appearance, i.e., having a uniform color even in resin flow lines or resin weld lines, and in which there is no degradation in the physical properties of the polymer resin contained therein can be manufactured at a low cost.

  • Publication number: 20060211105
    Abstract: The present invention relates to a novel strain, Rhodococcus erythropolis LG12, having acrylic acid degrading activity and resistance to acrylic acid, and a method for removing acrylic acid from acrylic acid-containing contaminants using the same. The strain according to the invention has not only acrylic acid degrading activity but also resistance to a high concentration of acrylic acid thus will be useful to remove acrylic acid from acrylic acid-containing contaminants.

  • Publication number: 20060194277
    Abstract: A method for producing target proteins by deleting or amplifying ibpA and/or ibpB genes coding for inclusion body-associated proteins. Two methods for producing target proteins using ibpA and/or ibpB genes coding for inclusion body-associated proteins of E. coli are described, The first method enhances the secretory production and activity of target proteins using ibpA and/or ibpB genes-deleted bacteria. The second method enhances the production of target proteins in the cytoplasm and also converts the target proteins from soluble form to insoluble inclusion body, using ibpA and/or ibpB gene-amplified bacteria.

  • Publication number: 20050152667
    Abstract: The present invention relates to a method for establishing a recording quality in a digital recording device. In the present invention, still images associated with a plurality of recording qualities having different levels are displayed on a recording-quality selection menu image, and data streams are recorded at a recording quality selected through the recording-quality selection menu image. The still images are generated while a picture captured from video streams being differently encoded at the recording qualities. Otherwise, the still images are pre-stored in the digital recording device while being classified according to the recording qualities, and are read from the digital recording device. Also, the still images are displayed along with information associated with recording times for every recording quality.

  • Publication number: 20050123994
    Abstract: The present invention relates to a composition containing sHSPs for prevention of protein degradation and a composition for two-dimensional (2-D) gel electrophoresis. Furthermore, the present invention relates to the improved method of 2-D gel electrophoresis, which is characterized by using sHSPs. According to the present invention, decreasing of protein spots was prevented in the 2-D gel electrophoresis, thereby obtaining 2-D gel with much more protein spots.

  • Publication number: 20050037473
    Abstract: The present invention relates to a method for producing middle-chain-length polyhydroxyalkanoate (MCL-PHA) using a maoC gene. The producing method of MCL-PHA according to the present invention comprises the steps of transforming a microorganism with the maoC gene to give a transformant, the microorganism being deleted of a fadB gene and containing a PHA synthase gene; culturing the transformant in medium containing a C6-10 carbon source; and obtaining PHA consisting of monomers with 6-10 carbon atoms. When the maoC gene whose function has not yet been established is used according to the present invention, high quality PHA with a higher number of carbon atoms than the prior PHA can be produced at a higher efficiency.
