A multistage process that includes cloning, physical mapping, subcloning, determination of the DNA SEQUENCE, and information analysis.
The sequence of transfers of matter and energy from organism to organism in the form of FOOD. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. PLANTS, which convert SOLAR ENERGY to food by PHOTOSYNTHESIS, are the primary food source. In a predator chain, a plant-eating animal is eaten by a larger animal. In a parasite chain, a smaller organism consumes part of a larger host and may itself be parasitized by smaller organisms. In a saprophytic chain, microorganisms live on dead organic matter.

Many marine-derived polysaccharides and their analogues have been reported as showing anticancer and cancer preventive properties. These compounds demonstrate interesting activities and special modes of action, differing from each other in both structure and toxicity profile. Herein, literature data concerning anticancer and cancer preventive marine polysaccharides are reviewed. The structural diversity, the biological activities, and the molecular mechanisms of their action are discussed.
A newly designed sunscreen has harnessed the biological strategies that aquatic organisms evolved to prevent the negative effect of UV radiations. Despite being made from fish mucus, crustacean shells and fungi, the sunscreen is more effective than current products and can be applied to skin as well as your backyard furniture. There is an urgent need to create new sunscreens that are an improvement on the currently used UV-protective products. Existing options are made from a combination of synthetic and natural compounds that can be unstable and do not provide full protection against both UV-A and UV-B. They also pose a threat to the environment and human health with long-term use. Professor Vincent Bulone and colleagues exploited the UV-absorbing properties of small compounds - molecular sunscreens isolated from algae, microorganisms and the mucus and lenses of reef fish. These compounds, called mycosporines are synthesised to naturally protect organisms from UV radiations. Mycosporines have

The regressions of all equations are very obvious. logP is the logarithm of hydrophobicity parameter; the higher the logP values, the stronger the hydrophobicity, the easier the compound is bioconcentrated in a organism; ELUMO is an electrophilicity parameter, and it appears in directly proportional to the electronic affinity of the compound. The lower the ELUMO values, the stronger the electrophilicity (Wang, 1981). Both the data in Table 1 and above QSAR equations show that the toxicity of anilines and phenols to the three kinds of aquatic organisms is related chiefly to their ability to the penetrate into the cell by to the electronic interactions of the chemicals with the active site of action through a variety of electronic processes. To those compounds containing one -NO or polyhalogen, their logP values are higher and ELUMO values are negative, such as 2,4-Dinitrophenol and dichloroanilines, their toxicity is probably controlled not only by hydrophobic but also by electronic factors. This ...

The geological, biological and geochemical features of a particular field of hydrothermal vents, discovered in the Panarea Volcanic Complex during a research survey carried out in 2015, are described for the first time. The site, located at 70-80 m depth off the South-western coast of the islet of Basiluzzo, was named Smoking Land for the presence of a large number of wide and high active chimneys and was characterized in terms of dissolved benthic fluxes, associated macrofauna and megafauna communities and preliminary mineralogy and geochemistry of chimney structures. On the whole field, a total of 39 chimneys, different in size and shape, were closely observed and described; 14 of them showed emission of low temperature hydrothermal fluids of marine origin characterized by acidified chemical conditions. The CTD and benthic chamber measurements highlighted that the Smoking Land is able to form a sea water bottom layer characterized by variable acidity and high DIC and trace elements ...

The fucoidanase from |i|Fusarium|/i| sp. (LD8) was obtained by solid-state fermentation. The fermented solid medium was extracted by citric acid buffer, and the extracts were precipitated by acetone and purified by Sephadex G-100 successively. The results showed that the specific fucoidanase activity of purified enzyme was 22.7-fold than that of the crude enzyme. The recovery of the enzyme was 23.9%. The purified enzyme gave a single band on SDS-PAGE gel, and the molecular weight of fucoidanase was about 64 kDa. The isoelectric point of the enzyme was 4.5. The enzyme properties were also studied. The results showed that the optimum temperature and pH were 60°C and 6.0, respectively; the temperature of half inactivation was 50°C, and the most stable pH for the enzyme was 6.0. |inline-formula||mml:math id=M1 xmlns:mml=http://www.w3.org/1998/Math/MathML||mml:mrow||mml:msub||mml:mrow||mml:mi|K|/mml:mi||/mml:mrow||mml:mrow||mml:mi|M|/mml:mi||/mml:mrow||/mml:msub||/mml:mrow||/mml:math||/inline-formula|,
Natural products have been a rich source of compounds with structural and chemical diversity for drug discovery. However, antibiotic resistance in bacteria has been reported for nearly every antibiotic once it is used in clinical practice. In the past decade, pharmaceutical companies have reduced their natural product discovery projects because of challenges, such as high costs, low return rates, and high rediscovery rates. The largely unexplored marine environment harbours substantial diversity and is a large resource to discover novel compounds with novel modes of action, which is essential for the treatment of drug-resistant bacterial infections. In this Review, we report compounds derived from marine sources that have shown in-vivo and in-vitro efficacy against drug-resistant bacteria. Analysis of the physicochemical properties of these marine natural products with activity against drug-resistant bacteria showed that 60% of the compounds have oral bioavailability potential. Their overall ...
In this study, polysaccharides of marine origin (agar, alginate and κ-carrageenan) were used to embed nutrients to fabricate biocomposites to be employed in animal feeding. The consistency of biocomposites in water has been evaluated up to 14 days, by several methods: swelling, nutrient release and granulometric analysis. Biocomposites were produced with varying percentages of nutrients (5%-25%) and polysaccharides (1%-2%-3%). All possible biopolymer combinations were tested in order to select those with the best network strength. The best performing biocomposites were those manufactured with agar 2% and nutrients 10%, showing the lowest percentage of water absorption and nutrient release. Biocomposites made of agar 2% and nutrients 10% were the most stable in water and were therefore used to analyze their behavior in water with respect to the release of quercetin, a phenolic compound with demonstrated high antibacterial and antioxidant activities. The leaching of such molecules in water was therefore

The aquatic block of lectures starts with an examination of the physiological adaptations for invertebrate marine life living within sea water, arguably the most trouble-free stable environment for animals on the planet. The lectures progress onto marine vertebrates (Myxiniformes, Chondrichthyes and teleosts), then moves to deal with brackish water, and on into the freshwater environment from both an invertebrate and vertebrate perspective. After which, the thermal adaptation of aquatic organisms within a variety of habitats is discussed, covering the open ocean, polar regions, intertidal etc. Specialised topics, such as regional endothermy are also discussed. Locomotion within the aquatic environment is governed by organism size and Reynolds forces; the lectures will discuss swimming in relation to viscosity and inertia, across a range of aquatic organisms both invertebrate and vertebrate. The cheap alternative to swimming employed by many aquatic invertebrates, employing buoyancy and increased ...

The Census of Antarctic Marine Life (CAML) and its polar counterpart, Arctic Ocean Diversity, have pioneered new understandings of the evolution and diversity of life.. Led by the Australian Antarctic Division, CAML coordinated 18 major research voyages to Antarctica and the Southern Ocean during the IPY. Australian scientists participated in three CAML voyages focusing on waters adjacent to East Antarctica - known as the Collaborative East Antarctic Marine Census (CEAMARC). These voyages, aboard Japans Umitaka Maru, Frances LAstrolabe and Australias Aurora Australis, studied sea-bed communities and the deep pelagic (open ocean) zone of the region adjacent to Terre Adélie and George V Land.. Altogether, CAML revealed that Antarctica is a single bioregion united by the Circumpolar Current - the largest current in the world. Previously thought to be low in species diversity, the Antarctic is now known to have an unexpected richness of life. In addition, molecular techniques show Antarctica to ...

Dive and explore marine ecosystems to discover their mysteries: how to recognize marine fauna? We explore all kind of questions about marine life.
The marine habitat represents an untapped source of bioactive compounds with promising therapeutic potential and clinical applications. As a result of intensive bioprospecting efforts in the search of bioactive secondary metabolites from the marine environment, during the last decade there has been a considerable increase in the number of marine natural products that have been successfully launched into the drug market (i.e., Yondelis®, Adcertis®, Halaven®). In addition, numerous potential marine-derived drug candidates are currently in advanced stages of clinical development. This has partly been driven by advances in sampling and analytical techniques as well as by novel high-throughput screening platform technologies. Nevertheless, the limited supply of promising bioactive metabolites from their natural sources remains one of the major bottlenecks in marine natural products drug discovery and development.As an alternative to the environmentally unsustainable wild harvesting, marine invertebrate
The factors controlling the relative abundances of Archaea and Bacteria in marine sediments are poorly understood. We determined depth distributions of archaeal and bacterial 16S rRNA genes by quantitative PCR at eight stations in Aarhus Bay, Denmark. Bacterial outnumber archaeal genes 10-60-fold in uppermost sediments that are irrigated and mixed by macrofauna. This bioturbation is indicated by visual observations of sediment color and faunal tracks, by porewater profiles of dissolved inorganic carbon and sulfate, and by distributions of unsupported 210Pb and 137Cs. Below the depth of bioturbation, the relative abundances of archaeal genes increase, accounting for one third of 16S rRNA genes in the sulfate zone, and half of 16S rRNA genes in the sulfate-methane transition zone and methane zone. Phylogenetic analyses reveal a strong shift in bacterial and archaeal community structure from bioturbated sediments to underlying layers. Stable isotopic analyses on organic matter and porewater ...
Definition (http://www.fao.org/fishery/cwp/handbook/j/en). Aquaculture is the farming of aquatic organisms: fish, molluscs, crustaceans, aquatic plants, crocodiles, alligators, turtles, and amphibians. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc. Farming also implies individual or corporate ownership of the stock being cultivated. For statistical purposes, aquatic organisms which are harvested by an individual or corporate body which has owned them throughout their rearing period contribute to aquaculture, while aquatic organisms which are exploitable by the public as a common property resource, with or without appropriate licences, are the harvest of capture fisheries. (FAO). Preferred Units: N/A. Scope Note: ...
Analogue approach justification Silicic acid is a naturally-occurring substance which is not harmful to aquatic organisms at relevant concentrations. Silicic acid is the major bioavailable form of silicon for aquatic organisms and plays an important role in the biogeochemical cycle of silicon (Si). Most living organisms contain at least trace quantities of silicon. For some species Si is an essential element that is actively taken up. For example, diatoms, radiolarians, flagellates, sponges and gastropods all have silicate skeletal structures (OECD SIDS 2004, Soluble silicates). Silicic acid has been shown to be beneficial in protection against mildew formation in wheat and to be non-phytotoxic in non-standard studies (Côte-Beaulieu et al. 2009). Silicic acid is therefore not expected to be harmful to organisms present in the environment. To support this view, all the available studies with aquatic organisms report no effects at 100 mg/l nominal loading in short-term toxicity studies (see Table ...
In this review paper, the latest literature on the functional properties of phospholipids in relation to inflammation and inflammation-related disorders has been critically appraised and evaluated. The paper is divided into three sections: Section 1 presents an overview of the relationship between structures and biological activities (pro-inflammatory or anti-inflammatory) of several phospholipids with respect to inflammation. Sections 2 and 3 are dedicated to the structures, functions, compositions and anti-inflammatory properties of dietary phospholipids from animal and marine sources. Most of the dietary phospholipids of animal origin come from meat, egg and dairy products. To date, there is very limited work published on meat phospholipids, undoubtedly due to the negative perception that meat consumption is an unhealthy option because of its putative associations with several chronic diseases. These assumptions are addressed with respect to the phospholipid composition of meat products. ...

PART I. A deuterium exchange analysis of 2,5-dihydroxyacetanilide (5) in the absence and presence of DHAE II was performed to test the nucleophilicity of the substrate in the absence and presence of catalyst. In addition, inhibition studies using 1,4-dihydroxybenzene were performed to determine the role that the N-acetyl side chain group plays in the formation of a stable substrate-enzyme complex. 1,4-Dihydroxybenzene was found to be a weak inhibitor, indicating that the N-acetyl functionality may play a crucial role in forming stable enzyme-substrate interactions. The synthesis of dihydroquinoline 7 was pursued to investigate the enzyme substrate interactions between DHAE and a substrate where the N-acetyl side chain has been fixed to a particular orientation. Efforts towards formation of the C6-C7 bond as a key step in the synthesis of dihydroquinoline 7 using palladium couplings, organocuprates, Lewis acid catalysts, and aza-Claisen reactions were pursued. To complement the results obtained, ...
The Cornell Collection of Blaschka Invertebrate Models is comprised of 570 exact glass replicas of marine invertebrates.

The biodiversity of marine microorganisms opens a promising potential for the discovery of new technical enzymes. During this study a characterization of marine microorganisms, isolated from Arctic or Antarctic ice, sea water or sediment from the ocean was performed based on a comprehensive strain collection at the Alfred-Wegener-Institut für Polar- und Meeresforschung. These marine psychrophilic bacteria indicated a wide spectrum of extracellular cold-active enzymes. 16S rRNA sequencing revealed that many of these psychrophilic bacteria represent new species. Characterization of selected isolates by means of transmission electron or raster electron microscopy showed remarkably pleomorphic cellular structures throughout their growth. The major part of this thesis focuses on a marine Antarctic, psychrophilic bacterium (strain ANT/505) isolated from sea ice covered surface water from the Southern Ocean, which was identified to express a very uncommon enzymatic activity for the marine environment, ...
The marine environment may contain over 80% of the worlds plant and animal species, and during the past decade over 5000 novel compounds have been isolated from marine organisms. The diversity of chemical compounds in the marine environment may be due in part to the extreme competition among organisms for space and resources … It is hypothesized that sessile marine organisms (for example, sponges, octocorals, tunicates and algae), have developed a diverse array of chemical compounds known as secondary metabolites or natural products for defense and competition. It is worth noting that this research group alone has discovered 235 bioactive compounds and has had over 117 patents issued over the last 10 years. Researchers in synthetic biology may be in a position to increase the payoff from this research. Once pharmaceuticals (or possibly specialty chemicals) have been derived from marine natural products, synthetic biology approaches developed at Berkeley could lower the cost of producing ...

Industrial biotechnology. Also known as white biotechnology, this field is based on the use of living cells and/or their enzymes for the sustainable production of chemicals, materials and fuels from renewable sources (79). This fast emerging area focuses on the development of clean bioprocesses with a reduction in greenhouse gas emissions, as well as energy and water usage (24). In the production of chemicals, biocatalytic reactions can replace a multistep synthesis with a single step involving low energy and less material input, producing higher quality products at a lower cost (93). More importantly, they sometimes enable the synthesis of products that may not be possible to synthesize otherwise (26). Current challenges are the development of novel and improved biocatalysts for the production of chemicals, as well as a cost-effective production of these enzymes (26). It is expected that 20% of the global chemicals (fine chemicals, specialties, polymers, etc.) and 60 % of fine chemicals will be ...
According to column 2 of REACH Annex IX, long-term testing shall be proposed by the registrant if the Chemical Safety Assessment indicates the need to investigate further the effects on aquatic organisms. Acute toxicity studies for all three trophic levels of aquatic organisms are available for the substance. Neither in the short-term fish test, the short-term daphnia test nor the algae test adverse effects could be observed within the tested concentration range. Further the substance has no potential for bioaccumulation, due to a very low log Kow, the investigation of further long-term tests seems to be unjustified and overestimated. On the basis of the present data the substance does not have to be classified and therefore no hazard to any compartment, including the environment, is expected ...
Marine diatoms. Light micrograph of an array of marine diatoms, part of the algae family. Diatoms are microscopic unicellular organisms that occur abundantly in marine and freshwater plankton. They form the basis of the food chain. The body is composed of two halves, which fit together like a tiny pill box. The cell walls contain silica, which is preserved in deposits known as siliceous or diatomaceous earths (ooze). Once hardened into rock it is called diatomite. The high porosity of this rock enables it to be used for filters, fillers and as a mild abrasive. (Magnification x25 at 35mm size). - Stock Image B946/0025

Evidence that support the marine environment as source of useful biocatalysts for application in several areas of industry pile up, both as scientific reports or patent applications. Marine microorganisms have to endure habitats characterized by extreme conditions of salinity, temperature or pressure. Their enzymes present concomitant features, viz. thermostability or halostability, which are appealing for practical applications. The food sector is a field where enzymes are used, given their specificity, compliance with strict regulations, relatively mild operational conditions required and environmental friendly nature. The specific features presented by marine enzymes can be advantageously used both for process improvement or to develop new processes and products. In the present review the role of relevant types of enzymes for the food sector is described and recent findings on those enzymes from marine are put into context. The information provided is illustrative that in spite of the relative
The invention relates to Algologie and Microbiology, and in particular to methods of allocation bacteriologically pure cultures of marine blue-green microalgae.. Currently, much attention is paid to the development of test systems for the evaluation of toxicity of the components of the marine ecosystems of water bodies, which requires the isolation of pure cultures of aquatic organisms, in particular microalgae. The standard procedure consists of isolating and growing algological pure cultures of algae, which then selects the most promising for biological testing. However, cultures of microalgae always be contaminated by bacterial microflora, spores and mycelium of fungi, which prevents further research, distorts the results. Purification from bacteria is a very time consuming process, because between algae and bacteria are dense biocenotic relationships. The mucous membranes of the algae serve as food source and shelter for microorganisms. Such a close relationship determines the difficulty of ...
In aquatic organisms, gills are a respiratory organ for the extraction of oxygen from water and for the excretion of carbon dioxide. Many small aquatic animals absorb oxygen through the surface of their bodies in general, but more complex forms have localized respiratory organs formed to present an adequate surface area to the external environment. They are usually thin plates of tissue or slender tufted processes and, with the exception of some aquatic insects, they contain blood or coelomic fluid which exchange gases through their thin walls. In the insects a unique type of respiratory organ is used, the tracheal gill, which contains air tubes. The oxygen in these tubes is renewed through the gills. Gills are developed in sea stars and sea urchins (Echinoidea) as thin protuberances on the surface of the body containing diverticula of the water vascular system. In the crustaceans, molluscs and some insects, they are tufted or plate-like structures at the surface of the body in which blood ...
