Probiotic properties of lactic acid bacteria isolated from animal sources

Deepti D. Dhere, Manisha A. Dhotre and V.S. Shembekar

Abstract: 

In the present research study an attempt was made to isolate the probiotic bacteria from animal sources and their probiotic properties were determined. Total15 milk samples (from Cow, Buffalo, and Goat) were used as source of probiotic bacteria. Out 57 isolates 11 isolates were screened as prominent probiotics, among them 3 isolates from Cow, Buffalo and Goat were found with significant probiotic properties. The probiotic properties of bacterial isolates were evaluated by performing seven different tests e.g. catalase test, bacteriocin assay, organic acid production study, resistance to acidic conditions, tolerance to bile, auto aggregation study and co-aggregation study. The collective score of all probiotic properties was used to determine its probiotic potential, where, the probiotic potential of isolates (PB1) from milk of domestic animals (Cow) was found to be highest i.e. (66.6%) as compared commercial isolate (PB5), which was 60%. The strains isolated from milk of Goat and Buffalo (PB2 and PB3) shows equal probiotic potential. Study suggested that use of these isolated probiotic bacteria can be a remedy to treat the bacterial infections in aquaculture.
