All tested lactibacilli strains showed high percentage of autoaggregation properties which ranges from 8.63% to 12.93% after incubation at 37 °C for 4 h. Meanwhile, the percentages of autoaggregation were significantly different (P < 0.05), and Q8-L strain showed the highest ability of autoaggregation among all the tested strains. While no difference was found between M5-L, J10-L and LGG strains (P > 0.05) as shown in Fig. 2.
