Effects of simulated gastric fluid (SGF) and bile salts (BS) on the survival of microencapsulated and free phages.

<p>Microencapsulated (ME) and free phages were exposed to SGF (A) at different pH values for 2, 5, 15 and 30 min or exposed to BS (B) at 1% and 2% for 1 and 3 h. Data represents mean values ± SEM of three independent experiments. Right, interaction plot of phage survival means calculated for timepoint at each phage condition. Different letters represent significant differences between groups (<i>P</i><0.05), whereas letters shared in common between or among the groups indicate no significant differences.</p>
