WebThe technique use to manipulate and isolate the E. coli bacteria is known as the streak plate procedure. The technique was developed to allow bacteria to multiply and produce many colonies, during the incubation period, depending on the amount of bacteria present. Each colony will contain millions of bacteria cells derived from a single parent ...
