The sequence ALGF EMTPEQIHQMI has 36% homology with the antimicrobial peptide alpha-basrubrin, identified in Ceylon spinach seeds (46). The peptide EGTYLDYIQNNGKTLGAEDSTNEFG WDNK has 36% homology with the lantibiotic lacticin 3147 (24). Overall, the MICs of the partially purified fractions from the water/salt-soluble extract of the sourdough fermented with L. plantarum 1A7 were lower than 10 mg/ml. These concentrations compared well with those of similar proteinaceous substances which also showed antifungal activities .
