  • Method for selective separation of free-astaxanthin from green algae
    Patent number: 7785823
    Abstract: There is provided a method of separating free-astaxanthin selectively from green algae and, more particularly, to a method of separating free-astaxanthin selectively from Haematococcus pluvialis, the method comprising: mixing a cell culture containing Haematococcus pluvialis with an alkanic solvent and stirring, thereby obtaining an alkanic solvent extract containing astaxanthin material including free-astaxanthin and astaxanthin ester (step 1); and mixing the alkanic solvent extract with an alcohol and stirring, thereby obtaining an alcoholic extract containing free-astaxanthin (step 2).
    Type: Grant
    Filed: February 21, 2007
    Date of Patent: August 31, 2010
    Assignee: Sungkyunkwan University
    Inventors: Sang-jun Sim, Chang-deok Kang
  • Method of detecting pathogenic microorganism in real-time, using modified flow-type surface plasmon resonance biosensor
    Patent number: 7718355
    Abstract: There is provided a method of detecting a pathogenic microorganism in real-time, using a modified flow-type surface plasmon resonance (SPR) biosensor, comprising the steps of: i) performing, in a batch-type, an immune reaction of a pathogenic microorganism and an antibody thereto; ii) selectively separating the pathogenic microorganism bound with the antibody; and iii) binding the pathogenic microorganism bound with the antibody on a surface of a chip of a flow-type SPR sensor system in real-time.

  • METHOD FOR SELECTIVE SEPARATION OF FREE-ASTAXANTHIN FROM GREEN ALGAE HAEMATOCOCCUS PLUVIALIS
    Publication number: 20070196894
    Abstract: There is provided a method of separating free-astaxanthin selectively from green algae and, more particularly, to a method of separating free-astaxanthin selectively from Haematococcus pluvialis, the method comprising: mixing a cell culture containing Haematococcus pluvialis with an alkanic solvent and stirring, thereby obtaining an alkanic solvent extract containing astaxanthin material including free-astaxanthin and astaxanthin ester (step 1); and mixing the alkanic solvent extract with an alcohol and stirring, thereby obtaining an alcoholic extract containing free-astaxanthin (step 2). The present invention can not only maximize the efficiency of separating astaxanthin in high concentration by providing a very simple process technique capable of recovering free-astaxanthin selectively from H.
