Mechanism of Antibacterial Activity of Bacillus amyloliquefaciens C-1 Lipopeptide toward Anaerobic Clostridium difficile

Table 1

The inhibition of the C-1 lipopeptide against Clostridium difficile in a plate test (the inhibition diameter showed in mm).

Clostridium difficile	Concentration (μg/ml)
