Streaking a plate for isolation
WebAfter streaking, incubate the culture plates for 24-48 hours at a temperature of 35-37 degrees Celsius within the incubator. Due to a limited population of bacteria in the streaking method, pure culture isolation is quite easier than the pour plate and the spread plate method. Through the streaking method, we can culture, isolate and study the ... WebThe inoculum is streaked over the agar surface to isolate colonies on at least a portion of the plate. Ideal results require that only a small amount of inoculum be used and that the surface of the plate be free of droplets of condensed moisture. Unless well isolated colonies are obtained, the plate is useless.
