Deconstruction of a multi-strain Bacillus-based probiotic used for poultry: an in vitro assessment of its individual components against C. perfringens

Table 2 The in vitro effect of single strains of Bacillus spp. on the concentration of C. perfringens using a co-culture method (Experiment 2)

Treatment	Average final C. perfringens concentration (Log₁₀ CFU/mL) ± SE
BS + CP	2.81^d ± 0.07
BC + CP	7.71^c ± 0.02
BP + CP	7.86^b ± 0.01
BL + CP	7.93^b ± 0.02
Control (CP only)	8.69^a ± 0.03

B. subtilis (BS); B. coagulans (BC); B. pumilus (BP); B. licheniformis (BL); C. perfringens (CP).
CFU: colony-forming units.
