The aim of this study was to isolate and characterize
Bacillus cereus
bacteriophages of various origins. Twenty-seven bacteriophages against
B. cereus
were isolated from various Korean traditional fermented foods and soils. Plaque size, transmission electron microscopy, virulence profile, and in vitro lytic activity of bacteriophage isolates were examined. Transmission electron microscopy confirmed
B. cereus
bacteriophages belonging to the family
Siphoviridae
. Among
B. cereus
bacteriophages with broad host range, 18 isolates (66.7%) did not harbor any
B. cereus
virulence factors. Among them, bacteriophage strain CAU150036, CAU150038, CAU150058, CAU150064, CAU150065, and CAU150066 effectively inhibited
B. cereus
in vitro within 1 h. Therefore, they are considered potential candidates for controlling the contamination of
B. cereus
in food or other applications.
