Negative selection through replica plating to screen for ampicillin sensitive colonies. Replica plating is a microbiological technique in which one or more secondary Petri plates containing different solid (agar-based) selective growth media (lacking nutrients or containing chemical growth inhibitors such as antibiotics) are inoculated with the same colonies of microorganisms from a primary ...
Esther Miriam Zimmer Lederberg (December 18, 1922 – November 11, 2006) was an American microbiologist and a pioneer of bacterial genetics.She discovered the bacterial virus lambda phage and the bacterial fertility factor F, devised the first implementation of replica plating, and furthered the understanding of the transfer of genes between bacteria by specialized transduction.
Replica plating is another technique used to plate out cells on agar plates. These four techniques are the most common, but others are also possible. It is crucial to work in a sterile manner to prevent contamination on the agar plates. [1] Plating is thus often done in a laminar flow cabinet or on the working bench next to a bunsen burner. [2]

Replica plating is a technique that transfers colonies from one plate to another in the same spot as the last plate so the different media plates can be compared side by side. It is used to compare the growth of the same colonies on different plates of media to determine which environments the bacterial colony can or cannot grow in (this gives ...
