To test the best antimicrobial activity that favors survival under
technological and gastrointestinal conditions of the AC-1 strain,
studies were conducted to compare this strain with two
probiotic reference strains (Lactobacillus plantarum B-7 from
Divisão de Engenharia de Bioprocessos e Biotecnologia, Federal
University of Paraná, Brazil and Bifidobacterium animalis subsp.
lactis BFL-9 from Danisco A/S, Copenhagen, Denmark).
