Procedure: 1. Mount a piece of sterile velvet by stretching it on a cylindrical metallic block (slightly smaller than Petri dish). 2. Place the block with velvet side facing upwards. 3. Invert the Petri dish with the lawn of bacterial cells (master plate) and gently press against the velvet.
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 plate (or master dish), reproducing the ...
Replica plating is an experimental technique that uses a printing-like transfer employing fabric with a pile (e.g., velveteen) to make multiple copies of an original culture plate with each microbial colony identified by its position on the culture plate.
In molecular biology and microbiology, replica plating is a 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 plate (or master ...
The procedure of replica plating technique is as follows; the master plate (mixture of prototroph and auxotroph) will be duplicated to medium with and without leucine by means of rubber stamp like device (called as replica plate).

Replica plating provides a rapid screening method for analyzing phenotypes. Colonies on a master plate are transferred to a sterile piece of velveteen. Copies of the mater plate are transferred to additional selective or indicator media to monitor phenotypes under additional conditions.
The procedure of replica plating technique is as follows; the master plate (mixture of prototroph and auxotroph) will be duplicated to medium with and without leucine by means of rubber stamp like device (called as replica plate).
May 11, 2012 · Replica-plate Procedure. Transferring cultures from one type of nutrient medium to another to test growth requirements becomes quite laborious if there are more than just a few strains. Replica plating is a method that permits simultaneous screening of a large number of microorganisms.
Sep 25, 2020 · This document describes several methods for isolating and detecting bacterial mutants, including replica plating, penicillin enrichment, and the Ames test. Replica plating involves transferring bacterial colonies from a "master plate" to replica plates with and without an amino acid to identify auxotrophic mutants.
