In microbiology, laboratory culture containing a single species of organism. A pure culture is usually derived from a mixed culture (containing many species) by methods that separate the individual cells so that, when they multiply, each will form an individually distinct colony, which may then be used to establish new cultures with the assurance that only one type of organism will be present. Pure cultures may be more easily isolated if the growth medium of the original mixed culture favours the growth of one organism to the exclusion of others.

Developing pure culture techniques is crucial to the observation of the specimen in question. The most common method to isolate individual cells and produce a pure culture, is to prepare a streak plate. The streak plate method is a way to physically separate the microbial population, and is done by spreading the inoculum back and forth with an incoluating loop over the solid agar plate. Upon incubation, colonies will arise and hopefully single cells will have been isolated from the biomass.
