PPT-Aim: To prepare pure culture by streak plate method.

Theory Generally bacteria exist in mixed population It is very rare to get a single and pure form For studying the cultural morphological and physiological characters of an individual species it is essential to separate them from the others to get in the form called pure culture There are many important methods for isolating pure culture from mixed .
