Introduction Quadrant streaking is a highly used method by biologists to obtain a pure culture by the inoculation of certain microorganisms. Here, the agar plate is quadrantal streaked i.e., divided into four equal sections. Hence, it is also called the 4 Quadrant Streak. Streaking is done to obtain a pure culture and identification of microorganisms.
