Lactic acid bacteria (LAB) have long been used in fermentations to preserve the nutritive qualities of various foods. Recently, a number of antimicrobial metabolites, e.g. cyclic dipeptides, phenyllactic acid, proteinaceous compounds, and 3-hydroxylated fatty acids have been isolated from lactic acid bacteria.1) The antioxidative effect of lactic acid bacteria was also reported.2)
This paper investigated antimicrobial activities and antioxidative effect of silk peptide transformed by lactic acid bacteria. Among the 38 lactic acid bacteria as lyophilized stock purchased, 25 of them showed good growth. I indicator strain were used for screening of antimicrobial activity and 19 strains of lactic acid bacteria showing antimicrobial activity. The antimicrobial compound from the 3 strains of lactic acid bacteria showing strong antimicrobial activity are under investigation. Free radical scavenging activities the culture supernatants were measured according to the modified method of Bilos.3) The highest radical scavenging activity was obtained in 3 lactic acid bacteria cultured under aerobic condition. Tyrosinase inhibition activites were also measured.
