The strains of lactococci showed no antimicrobial
activity except those of L. lactis subsp. lactis TAUL 71
and TAUL 78 and L. lactis subsp. lactis var. diacetylactis
TAUL 13. The two strains of Ln. mesenteroides subsp.
dextranicum and one of Ln. mesenteroides subsp. mesenteroides
inhibited 1–4 indicator strains. The two strains of
Lb. brevis inhibited three of the tested strains and only one
strain of Lb. plantarum (TAUL 1539) showed antibacterial
activity inhibiting 12 strains. None of the strains of Lb.
casei subsp. casei showed any inhibitory activity.
