| Spanish abstract | Se evaluó in vitro el potencial probiótico de cepas nativas aisladas de las heces de pollos asilvestrados (Gallus gallus) pertenecientes a los géneros Lactobacillus sp, Bacillus sp y levaduras tipo saccharomyces sp; se determinó la actividad probiótica mediante pruebas de resistencia al ácido (pH 3, 4, 5, 6, 7), sales de bilis (0,05, 0,1, 0,15, 0.3 %), tolerancia al NaCl (2, 4, 7, 10 %), actividad antagónica (Salmonella sp, E. coli), determinación del tipo de fermentación, crecimiento a temperaturas (28, 37, 43 °C) y capacidad de crecimiento. Las cepas con mayor tolerancia se identificaron a través de pruebas bioquímicas y fermentación de carbohidratos. Como resultado se observó que tres microorganismos: Saccharomyces sp. (3), Bacillus sp. (7) y Lactobacillus sp. (14) poseen propiedades probióticas |
| English abstract | Was evaluated in vitro the probiotic potential of native strains isolated from feces of wild chickens (Gallus gallus) belonging to the genera Lactobacillus sp., Bacillus sp. and Saccharomyces ; probiotic activity was determined by testing acid resistance (pH 3, 4, 5.6, 7), bile salts (0,05, 0,1, 0,15, 0,3%), tolerance to NaCl (2, 4, 7,10%), antagonistic activity (Salmonella spp, E. coli), production gas (glucose), growth temperatures (28, 37, 43 °C) and growth capacity. The most tolerant strains were identified by biochemical tests and carbohydrate fermentation. As a result it was found that three microorganisms: Saccharomyces sp. (3), Bacillus sp. (7) and Lactobacillus sp. (14) have probiotic properties |
