Furthermore, the term culture is more generally used informally to refer to "selectively growing" a specific kind of microorganism in the lab. It is often essential to isolate a pure culture of microorganisms. A pure (or axenic) culture is a population of cells or multicellular organisms growing in the absence of other species or types.
In microbiology, streaking is a technique used to isolate a pure strain from a single species of microorganism, often bacteria. Samples can then be taken from the resulting colonies and a microbiological culture can be grown on a new plate so that the organism can be identified, studied, or tested.
Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).
Agricultural monocultures refer to the practice of planting one crop species in a field. [15] Monoculture is widely used in intensive farming and in organic farming.In crop monocultures, each plant in a field has the same standardized planting, maintenance, and harvesting requirements resulting in greater yields and lower costs.

Much of the popularization of coffee is due to its cultivation in the Arab world, beginning in what is now Yemen, by Sufi monks in the 15th century. [2] Through thousands of Muslims pilgrimaging to Mecca, the enjoyment and harvesting of coffee, or the "wine of Araby" spread to other countries (e.g. Turkey, Egypt, Syria) and eventually to a majority of the world through the 16th century.
Cross-cultural research entails a particular statistical problem, known as Phylogenetic autocorrelation: tests of functional relationships (for example, a test of the hypothesis that societies with pronounced male dominance are more warlike) can be confounded because the samples of cultures are not independent.
