Abstract:
The blue mussel protein hydrolysates were separated using the consecutive chromatographic methods including ion exchange, gel filtration, high performance liquid chromatography to identify a potent antimicrobial activity. The fraction (MAMP) separated by HPLC, exhibiting strong activity against Gram-positive (E. coli, P. aeruginosa, S. dysenteriae, P. vuigaris, E. aerogenes) with the minimal inhibitory concentrations (MIC) from 15.63 to 31.25 μg/mL, and Gram-negative bacteria (S. aureus, B. subtilis and M. lysodeikticus) with MIC from 31.25 to 62.5 μg /mL. MAMP had good thermal and pH stability, and consisted of three main amino acids (Ser, Pro and Cys). The antimicrobial activity of MAMP was possibly related to its higher cysteine residues and contents of hydrophobic amino acid. Therefore, MAMP could be a natural antimicrobial source suitable for use as a food additive.
