| Lucibacterium | A genus of aerobic to facultatively anaerobic, motile, peritrichous bacteria containing Gram-negative rods. Their metabolism is fermentative, and they are usually luminescent. They occur on the surface of dead fish and in sea water. The type species is Lucibacterium harveyi. Origin: L. Luceo, to shine, + bacterium Lucibacterium harveyi, a species of luminescent bacteria found in sea water; it is the type species of the genus Lucibacterium. Synonym: Photobacterium harveyi.

| lucid | Clear, not obscured or confused, as in a lucid moment or lucid spoken expression. Origin: L. Lucidus, clear (05 Mar 2000) |
| lucid interval | In psychoses or delirium, a rational period appearing in the course of the mental disorder. (05 Mar 2000) |
| lucidification | Synonym: clarification. Origin: L. Lucidus, clear, + facio, to make (05 Mar 2000) |
| lucidity | The quality or state of being lucid. (05 Mar 2000) |
| lucifer | 1. The planet Venus, when appearing as the morning star; applied in Isaiah by a metaphor to a king of Babylon. "How art thou fallen from heaven, O Lucifer, son of the morning ! how art thou cut down to the ground which didst weaken the nations !" (Is. Xiv. 12) "Tertullian and Gregory the Great understood this passage of Isaiah in reference to the fall of Satan; in consequence of which the name Lucifer has since been applied to, Satan." (Kitto) 2. Hence, Satan. "How wretched Is that poor man that hangs on princes' favors! . . . When he falls, he falls like Lucifer, Never to hope again." (Shak) 3. A match made of a sliver of wood tipped with a combustible substance, and ignited by friction; called also lucifer match, and locofoco. See Locofoco. 4. <zoology> A genus of free-swimming macruran Crustacea, having a slender body and long appendages. Origin: L, bringing light, the morning star, fr. Lux, lucis, light + ferre to bring.

| luciferase | <enzyme> An enzyme from firefly tails that catalyses the production of light in the reaction between luciferin and ATP. Used by the male firefly for producing light to attract females and used in the laboratory in a chemiluminescence bioassay for ATP. (18 Nov 1997) |
| luciferases | Enzymes present in certain luminous organisms that act to bring about the oxidation of luciferins; energy produced in the process is liberated as bioluminescence; such enzymes can be used to detect very low concentrations of metabolites. Origin: L. Lux, light + fero, to bear (05 Mar 2000) |
| luciferin | <protein> Substrate for the enzyme luciferase that catalyses an oxidative reaction leading to photon emission (bioluminescence). (18 Nov 1997) |
| luciferins | A generic term referring to a substrate which, upon oxidation by the enzyme luciferase, produces bioluminescence. Luciferins isolated from different species may vary greatly in structure, although in many cases identical structures have been found in widely diverse animals. The american firefly, photinus pyralis, and its substrate have been studied extensively and is used in the assay of adenosine triphosphate. (12 Dec 1998) |
| luciferyl adenylate | An intermediate compound in the pathway of bioluminescence. Its precursor is the pigment luciferin. It is the substrate of the enzyme luciferase, which combines it with oxygen to make visible light. (09 Oct 1997) |
| lucifugal | Avoiding light. Origin: L. Lux, light, + fugio, to flee from (05 Mar 2000) |
| lucigenin | <protein> Compound used as a bystander substrate in assaying the metabolic activation of leucocytes by chemiluminescence. When oxidized by superoxide it emits light. (18 Nov 1997) |
| Lucilia | A genus of scavenging blowflies (family Calliphoridae), commonly called bluebottle or greenbottle flies, whose larvae feed on carrion or excrement; they occasionally cause wound infestation or myiasis. (05 Mar 2000) |
| Lucilia caesar | A species whose larvae formerly were used in the treatment of septic wounds. See: Phormia regina. (05 Mar 2000) |

| luciferase |
Luciferase is a generic name for enzymes commonly used in nature for bioluminescence. The name itself is derived from Lucifer, which means light-bearer. The most famous one is firefly luciferase (EC 1.13.12.7). In luminescent reactions, light is produced by the oxidation of a luciferin (a pigment), sometimes involving Adenosine triphosphate (ATP). The rates of this reaction between luciferin and oxygen are extremely slow until they are triggered by the presence of luciferase. ...
