Figure Lengend Snippet: Inhibition of foodborne pathogenic bacterial growth in the presence of CFS from Bacillus strains isolated from potential probiotic. Escherichia coli O157:H7 ATCC 35150 ( A ), Salmonella Enteritidis KCCM 12021 ( B ), or Staphylococcus aureus KCCM 11335 ( C ) were incubated in the presence of CFS from the Bacillus strains ( B. subtilis , B. atrophaeus , B. cereus , B. licheniformis , B. pumilus , B. amyloliquefaciens ) at 37 °C for 24 h. The bacterial growth was determined at OD 600 . The growth rate of foodborne pathogenic bacteria without CFS was assigned to 100% (Control).
