The streak plate method of isolation means to spread the microbes on plated agar media so that the individual cells or colony forming units (cfus). 33 streaking for isolation important: the best results are obtained if you flame/sterilize the loop and cool it between each streak, by touching the agar near the edge of the plate (heat sink). Best answer: streak plates are generally used for isolation of a define colony you use it to separate one cell from other cells great for separating but doesnt.
