چکیده انگلیسی


- LAB of avian origin were isolated for use as potential probiotics in animal production.
- These bacteria were evaluated and characterized to ensure their safety and efficiency.
- L. pentosus LB-31 showed the best in vitro characteristics as a potential probiotic.
- L. pentosus LB-31 was administered to broilers and showed beneficial properties.

In livestock production, lactic acid bacteria (LAB) are the most common microorganisms used as probiotics. For such use, these bacteria must be correctly identified and characterized to ensure their safety and efficiency. In the present study, LAB were isolated from broiler excreta, where a fermentation process was used. Nine among sixteen isolates were identified by biochemical and molecular (sequencing of the 16S rRNA gene) methods as Lactobacillus crispatus (n = 1), Lactobacillus pentosus (n = 1), Weissella cibaria (n = 1), Pediococcus pentosaceus (n = 2) and Enterococcus hirae (n = 4). Subsequently, these bacteria were characterized for their growth capabilities, lactic acid production, acidic pH and bile salts tolerance, cell surface hydrophobicity, antimicrobial susceptibility and antagonistic activity. Lactobacillus pentosus strain LB-31, which showed the best characteristics, was selected for further analysis. This strain was administered to broilers and showed the ability of modulating the immune response and producing beneficial effects on morpho-physiological, productive and health indicators of the animals.
