Isolation and identification of
lactobacillus
, which may be potentially prebiotic sources, from the
gastrointestinal tract of chicken

A
ntibiotics have been used in poultry industry for decades
to promote growth and protect animals from diseases,
followed by various side effects. In efforts of searching for
a better alternative, prebiotic is of extensive attention. The
EPS-based prebiotics that may be used for chicken might
been suggested as an effective strategy to decrease infection
in chicken. It is only in the last few years that LAB EPS have
taken attention with regard to prebiotic potential. For this
reason, in experiment 1, 119 bacteria of
lactobacilli
isolated
from the gastrointestinal tract of 24 chicken. For experiment
2, the isolates were tested for their exopolysaccharides
production levels. In these isolates, exopolysaccharides
production were assessed varies from 43-443 mg/L. In
experiment 3, for molecular identification, 11 isolates that
produced high EPS were selected. These
lactobacilli
isolates
were acknowledged using 16S rRNA sequence analysis.
As a result of the identification, isolates were identified as
Lactobacillus salivarius
(6 strains),
L. reuteri
(2 strains),
L.
aqilis
(2 strains) and
L. saerimneri
(1 strain). These bacteria
EPSs may be good alternatives to antibiotics in promoting
growth resulting from a beneficial modulation of the
intestinal microbiota, which leads to increased efficiency of
intestinal digestion in the host animal. Acknowledgements:
