Fig. 2From: In vitro assessment of safety and probiotic potential characteristics of Lactobacillus strains isolated from water buffalo mozzarella cheeseAdhesion capacity of Lactobacillus spp. strains to Caco-2 cells. The adhesion capacity is calculated using the ratio of the number of bacterial cells that remained attached to the total number of bacterial cells added initially to each well. Different lower case letters denote significant differences (P ≤ 0.05) among the adhesion capacities of the strains. The results are expressed as the mean ± SD. n = 3Back to article page
