Article Abstract:
The in vivo capacities for human intestinal mucosa colonization by different Lactobacillus strains are discussed. Experiments involved the administration of fermented oatmeal soup on17 strains originally isolated from human intestinal mucosa, one strain from rat intestinal mucosa and one strain from sour dough. The general ability of certain Lactobacillus strains in colonizing human intestinal mucosa was demonstrated notwithstanding individual dietary and physiological differences.

Article Abstract:
A study was conducted to analyze the genetic diversity of lactococcal strains determined from raw milk in the Registered Designation of Origin Camembert cheese. Phenotypic criteria and genotypic criteria were utilized to evaluate the relatedness of the strains to reference strains of Lactococcus species. Experimental results indicated that the recovery of lactococci isolates from natural sources correlated with the selective medium.

Article Abstract:
Lactobacillus casei CG11 was isolated from homemade cheese to study its production of Exoplysaccharide (EPS). A chemically defined medium was used to measure the EPS production and its sugar composition. Plasmid curing experiments were also carried out. It was found that an approximately 30 kb in size is linked to the EPS production by strain CG11 or in the regulation of EPSproduction.
