    supernatant.The supernatant was filtered through a .22 micron filter in order to extract phages. Since bacteria and other particles tend to be bigger than .22 microns, they would not fit through the filter, thus allowing only phages through. Mycobacterium smegmatis was then added to the supernatant in the amount of .5 mL. It was allowed to incubate for 5 days. After incubating, 1.4 mL of the enriched filtrate was pipetted into a microcentrifuge tube. This was done twice using the p1000. Both tubes were then centrifuged for 1 minute to separate the pellet and the supernatant. The supernatant, 1 mL from each tube (2 mL in total), was then filtered through a .22 micron filter in order to retrieve phages. A petri dish was divided in four sections and labeled as positive control,…
