What is a nutrient synthetic media?

Answer 1

A food prepared for the growth of microorganisms is given the general term

"Nutrient medium".

A large number of microorganisms will grow readily in or upon easily available nutrient media, as milk, bouillon, etc. Some microorganisms have widely differing food requirements and need for growth nutrient media differing widely in their composition.

Every culture medium must # Contain substances necessary for growth. # Be of suitable reaction. # Be contained in vessels which afford protection from contamination from outside sources.

Culture media may be classified as: I. Natural Media as occurring in nature, e.g., milk, potato and other vegetables, meat and meat products, blood and blood serum, egg, soil, etc. II. Prepared media, i.e., made in the laboratory. These are: (a) Of unknown chemical composition; e.g., nutrient agar, Gelatin, etc. (6) Synthetic; i.e., chemical composition known, e.g., Giltay solution for denitrifying organisms. Or as: I. Liquid Media. These include: A. Media made from animal tissue and fluids, e.g., nutrient broth, serum broth, carbohydrate broths, milk, blood, nitrate peptone solution, Dunham's solution. B. Media made from vegetable tissue. Among these are: Malt extract (germinated barley), beer wort, yeast extract, hay infusion, natural fruit juices, wines (fermented fruit juices). C. Synthetic media. II. Solid Media. These mav be classified as: A. Liquefiable, e.g., nutrient agar, nutrient gelatin. B. Non-liquefiable, including: 1. Media liquid in a natural state but which, once solidified, cannot be liquefied by physical means, e.g., media prepared from albuminous fluids and tissues such as egg, blood serum, etc., or synthetic media solidified with sodium silicate. 2. Media which are solid in the natural state, e.g., vegetable media such as potato, carrot, banana, etc.

Answer 2

Culture media are employed in the isolation and maintenance of pure cultures of bacteria.
A chemically-defined (synthetic) medium is one in which the exact chemical composition is known. The one that you mention is also nutrient rich which means that it has everything the bacteria need to grow.
