Abstract

Thirty-eight strains of , including 26 strains of biotype , were isolated from natural starters for Grana cheese. Seventeen strains had diaminopimelic acid (DAP) as a cytoplasmic (but not cell wall) component; 21 strains did not contain DAP. DAP-positive and galactose-negative strains may constitute new biotypes of Despite these variations, all of the strains studied displayed high deoxyribonucleic acid (DNA)-DNA homologies to the reference DNA, and the presence or absence of DAP is not considered to be of great taxonomic importance in
