An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens.

Mueller Hinton agar is a type of growth medium used in microbiology to culture bacterial isolates and test their susceptibility to antibiotics. This medium was first developed in 1941 by John Howard Mueller and Jane Hinton , who were microbiologists working at Harvard University.
The 10th annual U.S. Media Literacy Week Oct. 21-25 is your chance to answer that question, and to celebrate the importance of critical thinking about media as a fundamental life skill.
LB medium bottle and LB agar plate Plate medium agar LB. Lysogeny broth (LB) is a nutritionally rich medium primarily used for the growth of bacteria. Its creator, Giuseppe Bertani, intended LB to stand for lysogeny broth, [1] but LB has also come to colloquially mean Luria broth, Lennox broth, life broth or Luria–Bertani medium. [2]
MMN medium or Modified Melin-Norkrans medium is a type of agar growth medium, used to grow cultures of mycorrhizal fungi, ...
11.0 g Agar; Preparation: 1. Heat with frequent agitation and boil for 1 minute to completely dissolve. 2. Autoclave at 121 °C for 15 minutes. Cool to 50 °C. 3. Add 50 ml filter sterilized 10% lactose solution and mix well (the lactose can be exchanged to other carbohydrates e.g. glucose, resulting in GM17 medium)
Blood agar plates (BAPs) contain mammalian blood (usually sheep or horse), typically at a 5–10% concentration. BAPs are enriched, and differential media is used to isolate fastidious organisms and detect hemolytic activity. β-Hemolytic activity will show lysis and complete digestion of red blood cell contents surrounding a colony.
The first culture media was liquid media, designed by Louis Pasteur in 1860. [2] This was used in the laboratory until Robert Koch's development of solid media in 1881. [ 3 ] Koch's method of using a flat plate for his solid media was replaced by Julius Richard Petri's round box in 1887. [ 2 ]
