The highest yield of bacteriocin
produced by W. cibaria N23 was recorded at 20 h. The bacteriocin N23 remained stable after 2 h of
incubation at pH values between 2.0 and 8.0, and also for 15 min at 121 C. The bacteriocin produced by
W. cibaria N23 was found to have a narrow antibacterial spectrum, being able to inhibit only W. confusa
N31.
