AVILA, José et al. Probiotic Properties of Strains of Lactobacillus Genus Extracted from Intestinal  Tract of Farm Animals. Rev. cient. (Maracaibo) [online]. 2010, vol.20, n.2, pp.161-170. ISSN 0798-2259.

In the present work 14 bacterial strains were isolated and characterized from the intestinal tract of different farm animals, in order to select the strains whit probiotic potential. The selected strains were exerted to biochemical trails and also their probiotic properties were evaluated through acid resistance and bile salt trials, extreme temperature growth and the carbohydrate fermentation profile. The results allowed selection and identification of four lactobacillus strains with potential to be used as probiotic additives in animal feeding.
