15 Hourly Timepoints: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14Sampling is for qPCR assay to determine total extracellular phage (qEXT) and MPN (most probable number) assay to determine % phage infectivity.For qEXT and MPN sampling, 250 µL of sample in duplicates were collected and filtered through a 0.2 µm, 96-well filter plate, for each time point. (Flow through filtrate containing phage is the sample to analyze).
