Viability of FLB and ILB in ale beer during 24 days of storage at 21 °C followed by exposure to SGF (pH = 3.0) and SIF (pH = 6.5). aMeans with no letter in common between treatments within the same incubation time are significantly different (P < 0.05). A-CMeans with no letter in common within the same treatment across incubation times are significantly different (P < 0.05). FLB
= free Lactobacillus brevis and ILB
= immobilized Lactobacillus brevis
