HUMAN ABO BLOOD GROUP-BINDING LACTOBACILLI

摘要

Lactobacillus screening methods were carried out using surface plasmon resonance spectrums and human intestinal mucin and blood group antigens as probes. A trial to set selection criteria in the above-mentioned methods of screening for lactobacilli was made to adapt the methods to mass screening, and it was discovered that lactobacilli compatible with ABO blood groups can be screened by setting 100 RU as a criterion for judging bacterial binding under certain conditions. Using 238 lactobacillus strains, the above-mentioned screening methods and tests to judge their compatibility for the use of yogurt production were carried out, to at long last specifically discover bacillus strains compatible with blood groups A and O.
