PURE CULTURE Meaning and
Definition
-
A pure culture refers to a population of microorganisms that consists solely of a single species or strain. It is obtained by isolating and cultivating a specific microorganism in a laboratory setting, ensuring the absence of any other microorganisms. This is essential for conducting accurate and controlled experiments, as it allows researchers to study the characteristics and behaviors of a particular species without any interference or contamination from other microbial entities.
The process of obtaining a pure culture involves several steps. Initially, a small sample containing the desired microorganism is taken from a natural source or an existing culture. This sample is then streaked onto a solid growth medium, such as agar, in order to separate individual cells and obtain isolated colonies. These isolated colonies are then transferred onto new plates multiple times using sterile techniques, ensuring that only the desired microorganism is present in subsequent generations.
Pure cultures are essential for a variety of scientific and industrial applications. In research, they enable scientists to investigate the specific traits and mechanisms of a particular microorganism, such as studying the pathogenicity of bacteria or testing the production capabilities of yeast strains for biotechnological processes. In industrial settings, pure cultures are utilized for the production of antibiotics, vaccines, enzymes, and various other bioproducts, where strict control over the microbiological composition is required to ensure quality and consistency.
Overall, a pure culture serves as a fundamental tool for microbiologists, allowing for a deeper understanding of microbial species and their functions, as well as facilitating the development of beneficial applications in numerous fields.

Etymology of PURE CULTURE
The word "pure" originates from the Latin word "purus", meaning "clean" or "unadulterated". It was later adopted into French as "pur" and then borrowed into English. "Culture", on the other hand, comes from the Latin word "cultura", meaning "cultivation" or "tillage". It is derived from the verb "colere", which means "to cultivate" or "to till". When combined, the term "pure culture" refers to a microbiological term where a single species of microorganism is cultivated in a laboratory setting.
