Isolation streaking is the technique used to isolate bacterial colonies when inoculating organisms onto an agar plate. This involves streaking the inoculum back and forth across the surface of the agar in a zig-zag pattern, which helps to dilute the bacterial cells and separate them from one another, allowing for the growth of individual colonies. Option A (homogenization) and Option B (centrifugation) are not commonly used for bacterial colony isolation. Option D (culture streaking) is similar to isolation streaking, but is not as specific in terms of isolating individual colonies.
