enrichment culture defined in 1951 yearenrichment culture - enrichment culture;
enrichment culture - Microbiological technique allowing selection and isolation from a natural, mixed population of microorganisms of those having growth characteristics desired by the investigator. Involves culturing on a medium the composition of which is adjusted so as selectively to encourage growth of organisms of desired type; e.g. a medium containing cellulose as sole carbon source and incubated at high temperatures, will promote growth of thermophilic cellulose decomposers from a mixture of micro-organisms (such as occur in a crumb of soil) seeded oh to that medium. Encouragement of growth of physiologically and biochemically different sorts of micro-organisms can be achieved by altering various characteristics of medium, e.g. nutrient, pH, temperature, aeration. Used widely in bacteriology.
