As a guest, weddings can be a lot of fun, but they can also get a little pricey. From the engagement gift and the bridal shower to the bachelor or bachelorette party -- all the way to the wedding day, your bank account could get depleted pretty quickly.
Culture media. Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as agar or gelatin.

Culture media are employed in the isolation and maintenance of pure cultures of bacteria and are also used for identification of bacteria according to their biochemical and physiological properties. The manner in which bacteria are cultivated, and the purpose of culture media, varies widely. Liquid media are used for growth of pure batch cultures, while solidified media are used widely for the isolation of pure cultures, for estimating viable bacterial populations, and a variety of other purposes. The usual gelling agent for solid or semisolid medium is agar, a hydrocolloid derived from red algae. Agar is used because of its unique physical properties (it melts at 100oC and remains liquid until cooled to 40oC, the temperature at which it gels) and because it cannot be metabolized by most bacteria.
