| Abstract: | Recently a new antibacterial peptide had been purified from a trypsin hydrolyzates of bovine casein. The antibacterialactivity of Trpi (Tyr-rich polypeptide) was primarily studied in this work. The results demonstrated that the peptide showedgreat inhibitory activity against a number of microorganisms, especially Escherichia coli and Staphylococcus aureus. This findingsuggest that Trpi had a remarkable prospects of academic and applicable values. |
