Abstract
The work was carried out to isolate, characterize and to find out the antimicrobial activity of the whey protein from cow milk. In this study proteins were isolated and lyophilized and characterized by thin layer chromatography and SDS PAGE. Meanwhile, its antimicrobial activity was tested under in vitro conditions against the antibacterial pathogenic strains such as E.coli, S.aureus, K.pneumoniae, B.subtilis, P.aeroginsa and pathogenic antifungal strains such as Aspergillus niger, A. flavus and candida albicans. In this study, the derived whey protein showed an maximum and minimum antimicrobial activity against all the microorganisms both bacteria and fungi. According to the zone of inhibition (ZOI) the maximum zone was measured against S.aureus and A. niger.
