Cell survivability (log CFU ml−1) of three forms of Lactobacillus acidophilus and Lactobacillus rhamnosus (free, mono layer and double layer) after treatment in simulated gastric juice during 120 min (with 30 min interval) and then treatment in simulated intestinal juice with bile salt for 150 min (Circles represent bacterial count in each sample and the line is demonstrating the linear estimation of bacterial count)
