UPGMA dendrogram illustrating the correlation between the different denaturing gradient gel electrophoresis (DGGE) profiles from lactobacillus community obtained from the samples of the SHIME
compartments supplemented with the L. acidophilus CRL 1014 strain throughout model operation. Sequence characterization of the excised fragments indicated the presence of lac 1, L. acidophilus; lac 2, Lactobacillus casei; lac 3, Lactobacillus johnsonii and Lac 4, Lactobacillus sakei. R3: ascending colon, R4: transverse colon, R5: descending colon. B1, and B1: basal period, T1, T2, T3, and T4: treatment period with L. acidophilus 1014.
