Resumen
Enterococcus faecalis DBFIQ E24 was formerly characterised as a producer of antibacterial and antifungal substances. This strain is vancomycin sensitive, nonhaemolytic and gelatinase negative. SDS-PAGE revealed the presence of an active band located between 1060 and 3500 Da. After the application of a three-step purification procedure, two antimicrobial peptides were isolated. One of them is mostly active against Bacillus cereus with a molecular mass of 1364 Da, and the other one with a molecular mass of 1686 Da is mainly active against Escherichia coli. These results confirm the technological potential of E. faecalis DBFIQ E24 strain as a GRAS food biopreservative.
