主权项

1. A method for identifying and/or selecting a lactic acid bacterium that coaggregates with Streptococcus pyogenes, wherein the method comprises:
incubating Streptococcus pyogenes under conditions under which Streptococcus pyogenes forms a biofilm, adding the lactic acid bacterium to be investigated to a mixture for coaggregation between the Streptococcus pyogenes and the lactic acid bacterium and incubation of the mixture, and separating any unbound lactic acid bacteria by removing a supernatant and determining a presence of coaggregated lactic acid bacteria in the biofilm formed by Streptococcus pyogenes.
