Abstract

Pediococcus sp. ISK-1 isolated in our laboratory from well-aged Nukadoko, produces a bacteriocin which has a unique antimicrobial spectrum among pediocins. The antimicrobial activity was detected at the late exponential growth phase during fermentation and reached the maximum at the late stationary phase. The bacteriocin was stable at acidic pH, and more than 60% of the antimicrobial activity still remained even after being autoclaved at 121 °C for 20 min in the pH range of 3 to 8. This is the first report dealt with bacteriocin produced by lactic acid bacteria isolated from Nukadoko.
