Partial Characterization of Novel Bacteriocin SF1 Produced by Shigella flexneri and Their Lethal Activity on Members of Gut Microbiota

Table 2

Antimicrobial spectrum of bacteriocin SF1 against different target strains.

Bacterial species studied	Bacteriocin SF1 activity
E. coli	+
B. fragilis	+
S. boydii	−
S. sonnei	−
S. typhi	−
S. typhimurium	−
E. agglomerans	−
K. pneumoniae	−
C. freundii	−
M. morganii	−
P. stuartii	−
B. subtilis	−
S. aureus	−
L. monocytogenes	−

Three strains were tested from each bacterial species. +: bacterial species sensitive to bacteriocin; −: bacterial species not sensitive to bacteriocin.
