Effects of UV light and pH on the survival of microencapsulated and free phages.

<p>Microencapsulated (ME) and free phages were exposed to UV light for 15 and 30 min (A) or incubated at different pH values for 5 min at 37°C (B). Values are expressed as the phage survival percentage and represents mean ± SEM of three independent experiments. *, <i>P</i><0.001; **, <i>P</i><0.05 compared to free phages.</p>
