3.5. Antimicrobial spectrum and MIC values of bacteriocin F1
The antimicrobial spectrum and MIC values of bacteriocin F1 were detected by the microdilution technique. The results are shown in Table 3. Bacteriocin F1 was found to significantly inhibit not only Gram-negative bacteria (E. coli, S. enterica and S. dysenteriae), but also Gram-positive bacteria (S. aureus andB. thuringiensis) and fungi (A. flavus, A. niger, R. nigricans and P. glaucum).
