The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -
FDA: "Glowing" Seafood?
FDA: "Glowing" Seafood? http://web.archive.org/web/20080225162926/http://vm.cfsan.fda.gov/~ea... U.S. Food and Drug Administration Seafood Products Research Center July 1998 "GLOWING" SEAFOOD? by Patricia N. Sado* Introduction Seafood that produces a bright, blue-green light in the dark could be a meal from outer space or haute cuisine in a science fiction novel. The U. S. Food and Drug Administration (FDA) has received many consumer complaints about various seafood products "glowing" in the dark. Some of these consumers called their local health departments, poison control centers, and their U.S. Senator because they thought they had been poisoned by radiation. These consumers said they had trouble convincing people that their seafood was emitting light. One consumer took his imitation crabmeat to a local television station. Unfortunately his seafood had dried out and did not glow for the television reporters. Several consumers said that it took them many weeks before they found phone numbers for various government agencies to make inquiries. Several consumers thought their "glowing" seafood was due to phosphorescing phytoplankton, or even fluorescence. The consumers' seafood products "glowing" in the dark were not due to radiation or to fluorescence, which requires an ultraviolet light to trigger the reaction. These seafood products exhibited luminescence due to the presence of certain bacteria that are capable of emitting light. Luminescence by bacteria is due to a chemical reaction catalyzed by luciferase, a protein similar to that found in fireflies. The reaction involves oxidation of a reduced flavin mononucleotide and a long chain aliphatic aldehyde by molecular oxygen to produce oxidized flavin plus fatty acid and light (5, 12). -
Generation of Fluorescent Bacteria with the Genes Coding for Lumazine Protein and Riboflavin Biosynthesis
sensors Communication Generation of Fluorescent Bacteria with the Genes Coding for Lumazine Protein and Riboflavin Biosynthesis Sunjoo Lim, Eugeney Oh, Miae Choi, Euiho Lee and Chan-Yong Lee * Department of Biochemistry, Chungnam National University, Daejeon 34134, Korea; [email protected] (S.L.); [email protected] (E.O.); [email protected] (M.C.); [email protected] (E.L.) * Correspondence: [email protected]; Tel.: +82-42-821-5482 Abstract: Lumazine protein is a member of the riboflavin synthase superfamily and the intense fluorescence is caused by non-covalently bound to 6,7-dimethyl 8-ribityllumazine. The pRFN4 plasmid, which contains the riboflavin synthesis genes from Bacillus subtilis, was originally designed for overproduction of the fluorescent ligand of 6,7-dimethyl 8-ribityllumazine. To provide the basis for a biosensor based on the lux gene from bioluminescent bacteria of Photobacterium leiognathi, the gene coding for N-terminal domain half of the lumazine protein extending to amino acid 112 (N-LumP) and the gene for whole lumazine protein (W-LumP) from P. leiognathi were introduced by polymerase chain reaction (PCR) and ligated into pRFN4 vector, to construct the recombinant plasmids of N-lumP-pRFN4 and W-lumP-pRFN4 as well as their modified plasmids by insertion of the lux promoter. The expression of the genes in the recombinant plasmids was checked in various Escherichia coli strains, and the fluorescence intensity in Escherichia coli 43R can even be observed in a single cell. These results concerning the co-expression of the genes coding for lumazine protein and for riboflavin synthesis raise the possibility to generate fluorescent bacteria which can be used in the Citation: Lim, S.; Oh, E.; Choi, M.; field of bio-imaging. -

Abstract— Bioluminescence is an emission of light that produce These bioluminescent bacteria reported belong to the class by chemical reaction of enzymatic activity and biochemical of the Gammaproteobacteria. Among the bioluminescent bacteria living organism. The most abundant and widely distributed light reported, 17 bioluminescent species were currently known [7]. emitting organism is luminous bacteria either found as free-living in The luminous bacteria were also classified into three genera the ocean or gut symbiont in the host. These sets of species are diversely spread in terrestrial environment, freshwater and also in which are Vibrio, Photobacterium and Xenorhabdus marine ecosystem. These species of bacteria emit blue-green light (Photorhabdus) and the species within the genus Vibrio and provoked by the enzyme luciferase and regulated by the lux gene Photobacterium are usually exist in marine environment and operon and emitted at 490 nm. Some of the uses of the Xenorhabdus belong to terrestrial environment. bioluminescence are as genetic reporters and biosensors. General Some of the natural important of the bioluminescence in microbiological techniques have been used to isolate bioluminescent nature is in attracting prey, camouflage, deterring predators bacteria from water samples and squid. The characterization of 6 isolates bioluminescent bacteria was conducted macroscopic and and in aiding in hunting [8]. microscopically and was further analyses at molecular level using Bioluminescence is the phenomenon that consists of light 16sDNA and sequenced for species identification. -
Guide to the Coastal Marine Fishes of California
STATE OF CALIFORNIA THE RESOURCES AGENCY DEPARTMENT OF FISH AND GAME FISH BULLETIN 157 GUIDE TO THE COASTAL MARINE FISHES OF CALIFORNIA by DANIEL J. MILLER and ROBERT N. LEA Marine Resources Region 1972 ABSTRACT This is a comprehensive identification guide encompassing all shallow marine fishes within California waters. Geographic range limits, maximum size, depth range, a brief color description, and some meristic counts including, if available: fin ray counts, lateral line pores, lateral line scales, gill rakers, and vertebrae are given. Body proportions and shapes are used in the keys and a state- ment concerning the rarity or commonness in California is given for each species. In all, 554 species are described. Three of these have not been re- corded or confirmed as occurring in California waters but are included since they are apt to appear. The remainder have been recorded as occurring in an area between the Mexican and Oregon borders and offshore to at least 50 miles. Five of California species as yet have not been named or described, and ichthyologists studying these new forms have given information on identification to enable inclusion here. A dichotomous key to 144 families includes an outline figure of a repre- sentative for all but two families. Keys are presented for all larger families, and diagnostic features are pointed out on most of the figures. Illustrations are presented for all but eight species. Of the 554 species, 439 are found primarily in depths less than 400 ft., 48 are meso- or bathypelagic species, and 67 are deepwater bottom dwelling forms rarely taken in less than 400 ft. -

In this extreme environment, every photon Deep-sea teleost counts and may make the difference between life and death for its inhabitants. Two sources of light are present Dim-light vision in the deep-sea; downwelling light, that becomes dimmer and spectrally narrower with increasing depth until Ocular adaptation completely disappearing at around 1000 m, and bioluminescence, the light emitted by animals themselves. Retina Despite these relatively dark and inhospitable conditions, many teleost fish have made the deep-sea their home, Opsin relying heavily on vision to survive. Their visual systems have had to adapt, sometimes in astonishing and Bioluminescence bizarre ways. This review examines some aspects of the visual system of deep-sea teleosts and highlights the exceptional diversity in both optical and retinal specialisations. We also reveal how widespread several of these adaptations are across the deep-sea teleost phylogeny. Finally, the significance of some recent findings as well as the surprising diversity in visual adaptations is discussed. 1.

Gold core–shell nanoparticles were synthesized based on metallic cores, variable silica shell spacers covered with modified fluorescent silica layers. Ultraluminescent properties were obtained based on metal-enhanced fluorescence (MEF). Different silica spacers were syn- thesized to optimize the MEF enhancement factor (MEFEF). An optimal MEFEF was determined d− − ¼ equal to 9.5 for shorter silica spacers ( SiO2 10 nm). These nanoparticles were deposed on Escherichia coli bacteria at different concentration levels for Bioimaging generation over their surfaces. The best luminescent nanoparticles were deposed on intermediate and higher bacteria concentrations. In the presence of intermediate bacteria concentrations, the ultraluminescent nanoparticles adsorbed showed an increase of 35% to 45% compared with individual nanopar- ticles. -

Two complementary techniques to target critical substances (E. Dytkiewitz)7 1 Effect-directed Analysis using HPTLC and luminescent Vibrio fischeri bacteria Vera Baumgartner and Elisabeth Dytkiewitz 1.1 Characteristics Vibrio fischeri is a gram-negative, comma-shaped rod with flagella (refer to Figure 1), which lives as plankton or in symbiosis in all seas.[5] It was discovered by Beijerinck in 1889 and is also known as Aliivibrio fischeri.[3] Its special characteristic is its ability to glow (refer to subsection 1.2). Furthermore, the bacterium is robust, non-pathogenic and easy to cultivate, which makes it an ideal organism for the use in an analytical laboratory. Fig. 1: Photo of Vibrio fischeri 1 1.2 Generation of light As all bioluminescent organisms, Vibrio fischeri uses a so-called luciferin-luciferase-system for the generation of light. Thereby, a substance, the luciferin, and oxigen are transformed by an enzyme, the luciferase into light and water. The structure of the luciferin depends on the organism. Luciferase The reaction is: Luciferin + O2 −−−−−−! LIGHT + H2O Vibrio fischeri uses riboflavin-5-phosphate, a reduced flavin mononucleotide (FMNH2), as luciferin. -
