In the quadrant method, four equally sized sections are streaked. A Loopful of culture sample is streaked on the agar surface in area 1 Now again wire loop is flame sterilized and now the Petri plate is rotated at 90 degrees. If doing this in a lab, you would then incubate the agar plate for 24 hours after you streak it and evaluate whether you managed to isolate single bacterial colonies. As you might guess, the purpose of streaking for isolation is to produce isolated colonies of an organism on an agar plate.
