Blizzard [7]

Answer:

46 * 10^7 pfu/ml

Explanation:

Given -

Bacteriophage dilution = 0.1 ml

Volume of bacteria and plate with top agar  = 0.3 ml

Number of plaques = 46 pfu

Dilution (d) = 10^{-6}

Final concentration of phage stock is equal to

= \frac{pfu}{d*v}

Where pfu is the count of plaques

d is the dilution and v is the volume

Substituting the given values, we get -

\frac{46}{10^{-6} * 10^{-1}} \\= 46 * 10^7 pfu/ml
