Isolation, functional evaluation of probiotic properties and molecular identification of strains isolated from Iranian poultry's gut.

ABSTRACT:

Background and objectives

The use of probiotics as an alternative to antibiotics in poultry diets has attracted a lot of interest recently. In this context, the determination of probiotic characteristics was evaluated on several isolates obtained from Iranian poultry's gut.

Materials and methods

Probiotic characteristics such as hemolysis activity, acid, bile, gastric juice tolerate, in vitro adhesion assay, cell surface properties (hydrophobicity, auto-aggregation and co-aggregation) and antibiotic susceptibility test were evaluated. Finally, selected isolates identified molecularly after temperature-salt tolerance and extracellular enzyme activity (amylase, protease and cellulose).

Results

Out of 362 strains isolated from native poultry in three geographical
