| Abstract: | In the paper,combined enzymes were used for the hydrolysis of Antarctic krill Euphausia superba to obtain polypeptides,and the polypeptides contents and molecular weight distribution were determined by biuret method and liquid chromatography respectively.The antimicrobial activity of peptides and different molecular-weight fractions of polypeptides to six strains including Staphylococcus aureus,Bacillus subtilis,Micrococcus tetragenus,Escherichia coli,Saccharomyces cerevisiae,and Vibrio parahaemolyticus was... |
| Keywords: | Antarctic krill Polypeptide Antimicrobial activity |
