Pure culture can be prepared from a mixture of cultures by using the streak plate method. This enables the bacterial cells to be diluted to obtain a pure culture after many-folds dilution.
Pure culture is the one in which only one species, strain or clone of bacteria are grown. The pure culture enables to scientists to study in detail about its anatomy, lifestyle and potential uses or harms, without the interference of any other microbe.
