Cyprus conference, 2016 The character of earthworm antibacterial peptides ● The antibacterial peptide had stable physicochemical properties such as heat stability and wide pH scope properties such as heat stability and wide pH scope. There was little influence of pH 3, 5, 7, 9, 11 on the antibacterial activities of antibacterial tetradecapeptide antibacterial activities of antibacterial tetradecapeptide. And the antibacterial tetradecapeptide could keep when storing 180 days in home temperature storing 180 days in home temperature. ● The antibacterial mechanism and character of the five earthworm peptides was also researched in our group .
