RT Journal Article T1 The antimicrobial properties of different strains of Lactobacillus spp. isolated from kefir A1 Santos de la Sen, Antonio A1 San Mauro Martín, Diego A1 Sánchez, A. A1 Torres, J. M. A1 Marquina Díaz, Domingo AB The characteristics of 58 strains of Lactobacillus spp. isolated from kefir were studied. These strains were tested for adherence to human enterocyte-like Caco-2 cells, resistance to acidic pH and bile acid, antimicrobial activities against enteropathogenic bacteria and inhibition of Salmonella typhimurium attachment to Caco-2 cells. The best probiotic properties were observed in L. acidophilus CYC 10051 and L. kefiranofaciens CYC 10058.L. kefiranofaciens CYC 10058 produced an exopolysaccharide, which revealed that it was closely related to kefiran, a polysaccharide with antitumoral properties. This is the first in vitro study about the antimicrobial characteristics of the Lactobacillus population of kefir.
