Abstract

Present study was carried out to evaluate probiotic potential of novel bacterial strain i.e. L. paraplantarum KM1 (accession number KX671558 ) isolated 1 st time from pooled milk of Himachal Pradesh. L. paraplantarum KM1 exhibited highest viable counts at low acid value (i.e. at pH 2.0 and 3.0), bile tolerance (concentration 0.3%), autoaggregation (36.6%), co-aggregation with pathogenic bacteria (20.0%), cell surface hydrophobicity against O-xylene (95%), antimicrobial activity against various food borne pathogens (inhibition = 100%) and antibiotic sensitivity test which comes out to be sensitive against most of the antibiotics used. These all desirable attributes turn this strain a robust probiotic.
