Can a Pure culture prepared from mixed broth or mixed agar slant?
To identify the pure culture the best method is to perform sub culturing and it can be done either by on another agar plate by streak plate method or by pour plate methodThe next is to perform staining which give the difference in morphology if the culture is not pure.
