  • Abstract This study was conducted in order to evaluate the probiotic properties of lactic acid bacteria (LAB) isolated from intestinal tract of broilers and Thai indigenous chickens. The major properties, including the gastric juice and bile salts tolerance, starch, protein and lipid digesting capabilities, and the inhibition on certain pathogenic bacteria were investigated. Three-hundred and twenty-two and 226 LAB strains were isolated from ten broilers and eight Thai indigenous chickens, respectively....

  • The inhibitory activity of these spore-forming strains against Escherichia coli K88, E. coli K99, Salmonella typhimurium and Staphylococcus aureus was assessed using a disc plate diffusion assay. The six bacilli with the largest inhibition zones against the four indicator bacteria were chosen and assessed for their

  • These criteria are classified into its safety profile, performance within the GI tract and technological aspects of its development. The criteria are further dependent on the specific purpose of the strain and on the location for the expression of the specific property. With regards to safety, the probiotic strain must be of human origin, isolated from the gastrointestinal tract (GIT) of healthy individuals.

  • The surface of the human gut has a surplus area of 200-250 m2 in order to contain, between intraepithelial lymphocytes and lamina propria, Peyer’s patches and lymphoid follicles, the lymphoid tissue, while hosts a flora of about 800 different bacteria species with over 7000 strains. The 99% are obligate anaerobes and varies species were then classified using traditional anaerobic culture techniques.

  • In the present study intestinal delivery systems resistant to gastric juice, loaded with the probiotic bacteria Lactobacillus acidophilus LA14 and Bifidobacterium lactis BI07, were produced by the polyelectrolyte complexation. First, beads were prepared by the traditional extrusion method and nine formulations were developed using alginate as main carrier and the biopolymer, xanthan gum, as hydrophilic retardant polymer or the cellulose derivative, cellulose acetate phthalateDevelopment of microparticulate systems for intestinal delivery of Lactobacillus acidophilus and Bifidobacterium lactis.

  • The direct effect of probiotics in the lumen include the competition with pathogens for nutrients, production of antimicrobial substances and in particular organic acids competitive inhibition on the receptor sites, change in the composition of mucin hydrolysis of toxins, receptor hydrolysis, and nitric oxide (NO). The indirect effect of probiotics largely depends on the site of interaction between the probiotic and the effectors of the immune response. Thantasha et al.
