How many bacteria in one colony
WebHowever, transformation is an inefficient process — you will typically get less than a thousand colonies (often many fewer). Thus, the chance that any one bacteria would get two plasmids is extremely low (around 10⁻⁴ - 10⁻⁵). WebQ27 A 10-1 is performed on a culture of bacteria in order to perform viable plate counts. From the dilution, *0.1 mL* of solution is plated on solid media, and 265 colonies of bacteria grow on the plate. Assuming each colony came from a single bacterium, how many bacteria are in a single mL of the original culture?
