title: In Lactococcus lactis subsp. cremoris SK110 protein, instead of lipoteichoic acid, reacts with the group-N-specific antiserum.
abstract: The reaction between cell-surface components, isolated from two Lactococcus lactis subsp. cremoris strains, with their Group-specific antiserum were studied. No reaction between purified lipoteichoic acid and the antiserum was observed. Both strains, however, did belong to the lactococci (Group-N streptococci), as was demonstrated by the positive reaction between the antiserum and an acid- (Lancefield) or alkaline-extract. Experiments with proteolytic enzymes demonstrated the involvement of protein in the antigenic material in the latter reaction.
