| Eagle's minimum essential medium | A tissue culture medium similar to Eagle's basal medium but with different amounts and a few exclusions (e.g., antibiotics and phenol red). (05 Mar 2000) |
|---|---|
| Endo's medium | A medium containing peptone, lactose, dipotassium phosphate, agar, sodium sulfite, basic fuchsin, and distilled water; originally developed for the isolation of Salmonella typhi, this medium is now most useful in the bacteriological examination of water; coliform organisms ferment the lactose, and their colonies become red and colour the surrounding medium; non-lactose-fermenting organisms produce clear, colourless colonies against the faint pink background of the medium. Synonym: Endo's medium. (05 Mar 2000) |
| transport medium | A medium for transporting clinical specimens to the laboratory for examination. (05 Mar 2000) |
| enriched medium | <cell culture> A growth medium which contains extra unusual nutrients or contains higher concentrations of regular nutrients than a standard medium. It is used to grow auxotrophs (organisms which lack the ability to make something essential for growth). (09 Oct 1997) |
| external medium | The medium or fluid in which a disperse is suspended. Synonym: continuous phase, dispersion medium, dispersion phase, external medium. (05 Mar 2000) |
| foramen lacerum medium | <anatomy> An irregular aperture, filled with cartilage (basilar cartilage) in the living, located between the apex of the petrous part of the temporal bone, the body of the sphenoid, and the basilar part of the occipital bones. Several structures pass along the margins of the foramen in a nearly horizontal direction but no structures pass through vertically. Synonym: foramen lacerum medium, lacerated foramen, sphenotic foramen. (05 Mar 2000) |
| ligamentum hyothyroideum medium | <anatomy> The central thickened portion of the thyrohyoid membrane. Synonym: ligamentum thyrohyoideum medianum, ligamentum hyothyroideum medium. (05 Mar 2000) |
| ligamentum tibiofibulare medium | The dense fibrous layer that connects the interosseous margins of the tibia and fibula, forming the upper portion of the tibiofibular syndesmosis and, with the bones and intermuscular septa, creating anterior and posterior comparments of the leg. Synonym: membrana interossea cruris, ligamentum tibiofibulare medium. (05 Mar 2000) |
| Lowenstein-Jensen medium | Primary mycobacterial recovery media composed of fresh whole eggs, defined salts, glycerol, potato flour, and malachite green (as an inhibitory agent). Synonym: Lowenstein-Jensen medium. (05 Mar 2000) |
| American Type Culture Collection | <cell culture> A key resource for cultured cells, located in Rockville, USA. (12 Dec 1998) |
| animal cell culture | <cell culture> Mammalian cells are fragile and harder to grow than other cell types, but their large-scale culturing is an economic boon because it allows for the production of proteins that are otherwise difficult or expensive or unethical to extract from living organisms. The cells are immobilised on a substrate and then perfused with culture medium, The cells are in a free suspension which is very gently mixed and aerated. (12 Nov 1997) |
| anoxic culture | A culture of anaerobicmicrobes which use inorganic substances other thanoxygen as their terminal electron acceptors. (09 Oct 1997) |
| anther culture | A plant culturing technique in which immature pollen is made to divide andgrow into tissue (either callus or embryonic tissue) in either aliquidmedium or on solid media. Pollen-containing anthers are removed from aflower and put in a culture medium, some microspheres survive and developinto tissue. If embryonic tissue develops, its put in a medium favorablefor shoot and root development, if its callus tissue, its put in asolution of hormones that will spur it to differentiate and develop shootand root tissue. (09 Oct 1997) |
| axenic culture | <cell culture, microbiology> A culture that contains only one microbial species. (02 Jan 1998) |
| batch culture | A closed system culture of microorganisms with specific nutrient types, temperature, pressure, aeration, and other environmental conditions, where only a few generations are allowed to grow before all nutrients are used up. Compare: continuous culture. (09 Oct 1997) |
