Agar (/ ˈ eɪ ɡ ɑːr / or / ˈ ɑː ɡ ər /), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from “ogonori” and “tengusa”.
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.

Yeast extract agar is a growth medium containing yeast extract. It may refer to: The nonselective yeast extract agar of Windle Taylor; YM (selective medium), for yeasts and molds; Buffered charcoal yeast extract agar, for Legionella
Nutrient agar is a general-purpose solid medium supporting growth of a wide range of non-fastidious organisms. It typically contains ( mass/volume ): [ 1 ] 0.5% peptone – this provides organic nitrogen
An agarose gel in a tray used for gel electrophoresis. Agarose is a heteropolysaccharide, generally extracted from certain red algae. [1] It is a linear polymer made up of the repeating unit of agarobiose, which is a disaccharide made up of D-galactose and 3,6-anhydro-L-galactopyranose.
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]
An osmophile is an extremophile microorganism adapted to environments generating high osmotic pressures, such as aqueous solutions with high salt or sugar concentrations (e.g., brines or sirups).
Sabouraud agar or Sabouraud dextrose agar (SDA) is a type of agar growth medium containing peptones. [1] It is used to cultivate dermatophytes and other types of fungi , and can also grow filamentous bacteria such as Nocardia .
