Summary 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 antigen material in the latter reaction.
