Figure 6.

Viability of spores from each sporeformer isolate (codes in x axis) when exposed for 4 h (T4, blue) to simulated stomach conditions (0.85% NaCl, pH 2, containing 3 mg ml⁻¹ pepsin) followed by 24 h (T24, yellow) exposition to simulated intestinal condition (LB, pH 8 containing 1 mg ml⁻¹ pancreatin and 0.3% bile salts). The initial viable counts (time 0 or T0) are depicted in grey Bacillus subtilis 168 was used as control and the results are the average of three independent experiments with error bars representing the standard deviation.
