Experimental set up: all culture plates were incubated at 37°C over night
Bacteriophage A
200 μl of bacteriophage A was added to 800 μl of E. coli broth culture. The mixed culture was then diluted 1/10 to
10-4. 100 μl of the mixed culture was then added to 9.9 ml molten agar and poured into the petri dish.
Bacteriophage B
100 μl of bacteriophage B was added to 900 μl of E. coli broth culture. The mixed culture was then diluted 1/10
to 10-5. 1000 ul of the mixed culture was then added to 9 ml molten agar and poured into the petri dish.
Bacteriophage C
250 μl of bacteriophage C was added to 750 μl of E. coli broth culture. The mixed culture was then diluted 1/10
to 10-6. 1000 μl of the mixed culture was then added to 9 ml molten agar and poured into the petri dish.

Determine the PFU /ml
Count the number of plaques on a each plate (repeats)
Determine the average plaques (round up to nearest 1)
Multiple by the volume dilution
Multiple by the dilution factor
Units = PFUs per millilitres
Show your working fully for each bacteriophage.
Which bacteriophage should you use in the mutagenesis
experiments and why?
