Simulation of human digestion in shake flasks. (a) Survival of L. crispatus L1 to gastric juices (pH 2.0, pepsine 3 g∙l⁻¹). Response of different doses of bacteria, high (1.8 · 10⁹ cells∙ml⁻¹) and low (6.0 · 10⁸ cells∙ml⁻¹), to the treatment. (b) Survival of L. crispatus L1 to pancreatic juices (pH 4.0, pancreatine 2 g∙l⁻¹, Oxgall in different concentrations). Effect of two different concentrations of bile salts on the viability of 1.0 · 10⁹ cells∙ml⁻¹.The asterisks indicate a statistically significant difference between samples with P < 0.01.
