[Adhesion of lactic acid bacteria to epithelium of different cavities of the human organism].

During investigation of adhesive properties of lactic acid bacteria it was found out that 11 strains adhered to buccal intestinal and vaginal epithelium of human. The highest adhesive activity was detected in enterococci (adhesive index 7.75-14.

[Screening of the strains of lactic acid bacteria possessing hypocholesterinemic activity and their practical use].

The strains of lactic acid bacteria (n = 139) belonging to Lactobacillus, Streptococcus, Enterococcus and Leuconostoc genera have been studied. It has been shown that neither of the strains used cholesterol as a source of carbon. Some strains (13.

[The role of the carbohydrate composition of the glycocalyx in some species of lactobacilli in the manifestation of their adhesive properties].

Availability of certain monosaccharides in the composition of glycocalyx of lactic acid bacteria (Lactobacillus plantarum--strains 337D and 11/16; Streptococcus thermophilus--strains S1 (nonmucous race) and S5 (mucous race), Enterococcus faecium (K-50) has been investigated with the help of plant lectins with certain carbohydrate specificity labelled by colloid gold. All the microorganisms under investigation were characterized by the presence of N-acetyl-D-galactosamine and N-acetyl-D-glucosamine in rather insignificant amounts. Glycocalyx of lactic acid bacteria was also characterized by availability of essential amount of L-fructose and low amount of sialic acid (except for S.

[The bacteriocinogenic and lysozyme-synthesizing activity of lactobacilli].

It was shown that lactic acid bacteria isolated from different sources produced along with lactic acid the bacteriocine substances. Strains producing bacteriocines were mainly isolated from digestive tract of people and calves. Bacteriogenic properties have been shown more frequently in the case of lactobacilli (7.
