Detailed explanation-1: -Enriched media contain the nutrients required to support the growth of a wide variety of organisms, including some of the more fastidious ones. They are commonly used to harvest as many different types of microbes as are present in the specimen.
Detailed explanation-2: -Broth cultures This allows a scientist to grow up large amounts of bacteria for a variety of downstream applications. Liquid cultures are ideal for preparation of an antimicrobial assay in which the experimenter inoculates liquid broth with bacteria and lets it grow overnight (they may use a shaker for uniform growth).
Detailed explanation-3: -In suspected outbreaks, microbiological testing is important both to identify foods that are more likely to be associated with disease and to pinpoint areas where controls have broken down. This allows future work to concentrate on areas that will have the greatest impact on safety.
