Phylogeny of marine and freshwater Shewanella: reclassification of Shewanella putrefaciens NCIMB 400 as Shewanella frigidimarina. (1/3538)

Dissimilatory Fe(III) reduction by Shewanella putrefaciens and related species has generated considerable interest in biochemical characterization of the pathways for anaerobic electron transfer in this organism. Two strains, MR-1 and NCIMB 400, have been extensively used, and several respiratory enzymes have been isolated from each. It has become apparent that significant sequence differences exist between homologous proteins from these strains. The 16S rRNA from NCIMB 400 was sequenced and compared to the sequences from MR-1 and other Shewanella strains. The results indicate that NCIMB 400 is significantly more closely related to the newly identified Shewanella frigidimarina than to the S. putrefaciens type strain. It is therefore proposed that NCIMB 400 should be reclassified as S. frigidimarina.  (+info)

Importance of air and water breathing in relation to size of the African lungfish Protopterus amphibius Peters. (2/3538)

1. Oxygen uptakes from air and water have been measured in relation to weight of the African lungfish Protopterus amphibius Peters. 2. Combined O2 uptake from air and water ranged from 60 ml O2 kg-1 h-1 STPD, in a 3-7 g specimen, to 30 ml O2kg-1 h-1, in a 255 g specimen. 3. While the combined O2 uptake changed by a factor of 2, within the weight range under study, the aquatic O2 uptake changed 8-fold within the same range. The smaller fish satisfy 70% of their O2 requirement by aquatic breathing compared to 10-15% in the grown specimens. 4. The pattern of bimodal breathing in P. amphibius is discussed in relation to the natural habitat of the species.  (+info)

Isolation from estuarine sediments of a Desulfovibrio strain which can grow on lactate coupled to the reductive dehalogenation of 2,4, 6-tribromophenol. (3/3538)

Strain TBP-1, an anaerobic bacterium capable of reductively dehalogenating 2,4,6-tribromophenol to phenol, was isolated from estuarine sediments of the Arthur Kill in the New York/New Jersey harbor. It is a gram-negative, motile, vibrio-shaped, obligate anaerobe which grows on lactate, pyruvate, hydrogen, and fumarate when provided sulfate as an electron acceptor. The organism accumulates acetate when grown on lactate and sulfate, contains desulfoviridin, and will not grow in the absence of NaCl. It will not utilize acetate, succinate, propionate, or butyrate for growth via sulfate reduction. When supplied with lactate as an electron donor, strain TBP-1 will utilize sulfate, sulfite, sulfur, and thiosulfate for growth but not nitrate, fumarate, or acrylate. This organism debrominates 2-, 4-, 2,4-, 2,6-, and 2,4,6-bromophenol but not 3- or 2,3-bromophenol or monobrominated benzoates. It will not dehalogenate monochlorinated, fluorinated, or iodinated phenols or chlorinated benzoates. Together with its physiological characteristics, its 16S rRNA gene sequence places it in the genus Desulfovibrio. The average growth yield of strain TBP-1 grown on a defined medium supplemented with lactate and 2,4,6-bromophenol is 3.71 mg of protein/mmol of phenol produced, and the yield was 1.42 mg of protein/mmol of phenol produced when 4-bromophenol was the electron acceptor. Average growth yields (milligrams of protein per millimole of electrons utilized) for Desulfovibrio sp. strain TBP-1 grown with 2,4,6-bromophenol, 4-bromophenol, or sulfate are 0.62, 0.71, and 1.07, respectively. Growth did not occur when either lactate or 2,4,6-bromophenol was omitted from the growth medium. These results indicate that Desulfovibrio sp. strain TBP-1 is capable of growth via halorespiration.  (+info)

Immunochemical detection and isolation of DNA from metabolically active bacteria. (4/3538)

Most techniques used to assay the growth of microbes in natural communities provide no information on the relationship between microbial productivity and community structure. To identify actively growing bacteria, we adapted a technique from immunocytochemistry to detect and selectively isolate DNA from bacteria incorporating bromodeoxyuridine (BrdU), a thymidine analog. In addition, we developed an immunocytochemical protocol to visualize BrdU-labeled microbial cells. Cultured bacteria and natural populations of aquatic bacterioplankton were pulse-labeled with exogenously supplied BrdU. Incorporation of BrdU into microbial DNA was demonstrated in DNA dot blots probed with anti-BrdU monoclonal antibodies and either peroxidase- or Texas red-conjugated secondary antibodies. BrdU-containing DNA was physically separated from unlabeled DNA by using antibody-coated paramagnetic beads, and the identities of bacteria contributing to both purified, BrdU-containing fractions and unfractionated, starting-material DNAs were determined by length heterogeneity PCR (LH-PCR) analysis. BrdU-containing DNA purified from a mixture of DNAs from labeled and unlabeled cultures showed >90-fold enrichment for the labeled bacterial taxon. The LH-PCR profile for BrdU-containing DNA from a labeled, natural microbial community differed from the profile for the community as a whole, demonstrating that BrdU was incorporated by a taxonomic subset of the community. Immunocytochemical detection of cells with BrdU-labeled DNA was accomplished by in situ probing with anti-BrdU monoclonal antibodies and Texas red-labeled secondary antibodies. Using this suite of techniques, microbial cells incorporating BrdU into their newly synthesized DNA can be quantified and the identities of these actively growing cells can be compared to the composition of the microbial community as a whole. Since not all strains tested could incorporate BrdU, these methods may be most useful when used to gain an understanding of the activities of specific species in the context of their microbial community.  (+info)

Dissimilatory reduction of Fe(III) and other electron acceptors by a Thermus isolate. (5/3538)

A thermophilic bacterium that can use O2, NO3-, Fe(III), and S0 as terminal electron acceptors for growth was isolated from groundwater sampled at a 3.2-km depth in a South African gold mine. This organism, designated SA-01, clustered most closely with members of the genus Thermus, as determined by 16S rRNA gene (rDNA) sequence analysis. The 16S rDNA sequence of SA-01 was >98% similar to that of Thermus strain NMX2 A.1, which was previously isolated by other investigators from a thermal spring in New Mexico. Strain NMX2 A.1 was also able to reduce Fe(III) and other electron acceptors. Neither SA-01 nor NMX2 A.1 grew fermentatively, i.e., addition of an external electron acceptor was required for anaerobic growth. Thermus strain SA-01 reduced soluble Fe(III) complexed with citrate or nitrilotriacetic acid (NTA); however, it could reduce only relatively small quantities (0.5 mM) of hydrous ferric oxide except when the humic acid analog 2,6-anthraquinone disulfonate was added as an electron shuttle, in which case 10 mM Fe(III) was reduced. Fe(III)-NTA was reduced quantitatively to Fe(II); reduction of Fe(III)-NTA was coupled to the oxidation of lactate and supported growth through three consecutive transfers. Suspensions of Thermus strain SA-01 cells also reduced Mn(IV), Co(III)-EDTA, Cr(VI), and U(VI). Mn(IV)-oxide was reduced in the presence of either lactate or H2. Both strains were also able to mineralize NTA to CO2 and to couple its oxidation to Fe(III) reduction and growth. The optimum temperature for growth and Fe(III) reduction by Thermus strains SA-01 and NMX2 A.1 is approximately 65 degrees C; their optimum pH is 6.5 to 7.0. This is the first report of a Thermus sp. being able to couple the oxidation of organic compounds to the reduction of Fe, Mn, or S.  (+info)

Morphological and compositional changes in a planktonic bacterial community in response to enhanced protozoan grazing. (6/3538)

We analyzed changes in bacterioplankton morphology and composition during enhanced protozoan grazing by image analysis and fluorescent in situ hybridization with group-specific rRNA-targeted oligonucleotide probes. Enclosure experiments were conducted in a small, fishless freshwater pond which was dominated by the cladoceran Daphnia magna. The removal of metazooplankton enhanced protozoan grazing pressure and triggered a microbial succession from fast-growing small bacteria to larger grazing-resistant morphotypes. These were mainly different types of filamentous bacteria which correlated in biomass with the population development of heterotrophic nanoflagellates (HNF). Small bacterial rods and cocci, which showed increased proportion after removal of Daphnia and doubling times of 6 to 11 h, belonged nearly exclusively to the beta subdivision of the class Proteobacteria and the Cytophaga-Flavobacterium cluster. The majority of this newly produced bacterial biomass was rapidly consumed by HNF. In contrast, the proportion of bacteria belonging to the gamma and alpha subdivisions of the Proteobacteria increased throughout the experiment. The alpha subdivision consisted mainly of rods that were 3 to 6 microm in length, which probably exceeded the size range of bacteria edible by protozoa. Initially, these organisms accounted for less than 1% of total bacteria, but after 72 h they became the predominant group of the bacterial assemblage. Other types of grazing-resistant, filamentous bacteria were also found within the beta subdivision of Proteobacteria and the Cytophaga-Flavobacterium cluster. We conclude that the predation regimen is a major structuring force for the bacterial community composition in this system. Protozoan grazing resulted in shifts of the morphological as well as the taxonomic composition of the bacterial assemblage. Grazing-resistant filamentous bacteria can develop within different phylogenetic groups of bacteria, and formerly underepresented taxa might become a dominant group when protozoan predation is the major selective pressure.  (+info)

In situ analysis of phototrophic sulfur bacteria in the chemocline of meromictic Lake Cadagno (Switzerland). (7/3538)

Comparative sequence analysis of a 16S rRNA gene clone library from the chemocline of the meromictic Lake Cadagno (Switzerland) revealed the presence of a diverse number of phototrophic sulfur bacteria. Sequences resembled those of rRNA of type strains Chromatium okenii DSM169 and Amoebobacter purpureus DSM4197, as well as those of four bacteria forming a tight cluster with A. purpureus DSM4197 and Lamprocystis roseopersicina DSM229. In situ hybridization with fluorescent (Cy3 labeled) oligonucleotide probes indicated that all large-celled phototrophic sulfur bacteria in the chemocline of Lake Cadagno were represented by C. okenii DSM169, while small-celled phototrophic sulfur bacteria consisted of four major populations with different distribution profiles in the chemocline indicating different ecophysiological adaptations.  (+info)

Transmission of epidemic Vibrio cholerae O1 in rural western Kenya associated with drinking water from Lake Victoria: an environmental reservoir for cholera? (8/3538)

Sub-Saharan Africa has the highest reported cholera incidence and mortality rates in the world. In 1997, a cholera epidemic occurred in western Kenya. Between June 1997 and March 1998, 14,275 cholera admissions to hospitals in Nyanza Province in western Kenya were reported. There were 547 deaths (case fatality rate = 4%). Of 31 Vibrio cholerae O1 isolates tested, all but one were sensitive to tetracycline. We performed a case-control study among 61 cholera patients and age-, sex-, and clinic-matched controls. Multivariate analysis showed that risk factors for cholera were drinking water from Lake Victoria or from a stream, sharing food with a person with watery diarrhea, and attending funeral feasts. Compared with other diarrheal pathogens, cholera was more common among persons living in a village bordering Lake Victoria. Cholera has become an important public health concern in western Kenya, and may become an endemic pathogen in the region.  (+info)

The drainage basin - as stated earlier - is an example of an open system, and many of the terms above are central to it. Below is a flow diagram of the drainage basin system:All rivers receive a water supply and the area of land this comes from is known as a drainage basin. The boundaries of the basin are known as the watershed and will usually be marked by areas of higher land.Drainage basins have many different characteristics that influence how quickly or slowly the main river within them responds to a period of intense rainfall, these are outlined in more detail in the section relating to storm hydrographs.Drainage patternsLand is drained by rivers in a variety of ways these are exhibited as drainage patterns.This is shown in the diagram below:Drainage densityThis relates to the number of streams in a particular drainage basin and can be measured by dividing total length of all streams in a basin (L) by its area (A).

The researchers simulations suggest that while there are many uncertainties, at least a third of species are likely to lose more than half their range under climate change". "Early action is often viewed as critical to preventing species loss under climate change but relies on models predicting into the future that are surrounded by uncertainty. Whilst predictions for a specific species may be considered unreliable, we can identify where the impact of climate change on freshwater biodiversity in NSW is most consistent, as well as where different sources of uncertainty are influential," said Dr Alex Bush, co-author of the Freshwater Biology study.. "We hope that by better communicating the distribution of modeling uncertainty, more strategic approaches can be employed to improve adaptive management and balance risks.". ...

Brackish water condition commonly occurs when fresh water meets seawater. In fact, the most extensive brackish water habitats worldwide are estuaries, where a river meets the sea. The River Thames flowing through London is a classic river estuary. The town of Teddington a few miles west of London marks the boundary between the tidal and non-tidal parts of the Thames, although it is still considered a freshwater river about as far east as Battersea insofar as the average salinity is very low and the fish fauna consists predominantly of freshwater species such as roach, dace, carp, perch, and pike. The Thames Estuary becomes brackish between Battersea and Gravesend, and the diversity of freshwater fish species present is smaller, primarily roach and dace; euryhaline marine species such as flounder, European seabass, mullet, and smelt become much more common. Further east, the salinity increases and the freshwater fish species are completely replaced by euryhaline marine ones, until the river ...

The Snakeskin Barb can add a lot of action to your freshwater aquarium - especially when kept in schools of six or more. Unlike other Barbs, however, these fish are not as bullish and most fair well in community aquariums with similarly sized, short-fin fish. They also grow to about 2 inches, unlike some barbs that quickly grow to a fairly large size. These fish are orange/red in color with deep green body splotches to give this beautiful specimen its "snakeskin" designation. Native to the blackwaters of Borneo, Indonesia, Snakeskin Barbs prefer soft, acidic aquarium water of the highest quality. A small school of this fish is a spectacular addition to any planted aquarium. Here, they will school in shaded areas, dart amongst plant stalks, and cruise the mid-level regions of your aquarium. As in other barb species, female Snakeskin Barbs are fuller bodied than males. Successful breeding requires strict attention to water softness and acidity, best obtained via peat filtration.

Only basins of rivers that empty into the ocean are included--excluded are tributary basins of rivers that flow into other rivers, and internal drainage basins then end in a internal sea or dry depression. For example, the Missouri River Basin is not here, since the Missouri flows into the Mississippi; and the basin of the Caspian Sea or Volga River are not here, either, since they never flow into an ocean.. Of course, there are many unlisted river basins here with higher peaks than many of the peaks on this list. But those peaks are not in a large basin.. ...

ing the ice-free period. By integrating all the time-series flux data curves in Figure 4, the sink of atmospheric CO2 in the littoral zones of Lake Baikal was estimated to be 3 - 5 g∙CO2∙m2.. 4. Discussion. Photosynthesis and the destruction of organic matter as well as the respiration of hydrobionts are the main factors causing diurnal fluctuations and seasonal variations in concentrations of dissolved gases and nutrients. The diurnal cycle of aquatic plant activity depends on light duration and, consequently, affects the maximal and minimal diurnal concentrations of the studied components.. Gas exchange processes in the air-water system are also affected by other factors (e.g., water temperature, wind speed, state of water surface), resulting in another time scale of variability. Therefore, the diurnal variation of chemical components concentrations in the water forms as a result of overlapping of changes of external hydrometeorological conditions with biological rhythms of the production ...

New research suggests sediment accumulation caused by industrial agriculture is the main threat to insects, crustaceans and other water macroinvertebrates.
A depth integrated fluorescent tracer procedure was developed in order to study the movement of individual sand grains along the beach profile. The following pattern of littoral zone tidal-cycle sedimentation was derived from the collected data: During flood tide a small portion of the sediment eroded in the lower backwash scour zone is deposited just seaward of the upper swash limit. It consists mainly of the finer grain sizes of the beach sand. Most of the eroded sediment, including a large part of the coarse grains, is deposited in the building of the step under the breaker zone. There is a slight diffusion of fine grains seaward of the step to the shoaling wave zone. Sediment moved landward with the advance of the breaker zone is concentrated at the step. Ebb tide sedimentation is similar, but two slight differences can be discerned. The fine sediment eroded as the lower backwash scour zone is translated seaward is deposited seaward of the upper swash limit; however, as it is being deposited ...

Bozeman, Mont.. Dearest Scott,. About 70 percent of the Earths surface is constantly wet. Of all that water, only 2.5 percent, or 8.4 million cubic miles, is not salty. Quite a bit of the freshwater is rather stale, since its been stuck for eons in glaciers, ice caps, and Siberia: 5.9 million cubic miles, to be exact. Still more freshwater is too far from human settlement for our use. The accessible freshwater left over after all these caveats is less than 0.08 percent of the water on the planet. I came across a handy image to help you visualize this number: If all of the Earths water were in a five-liter container, accessible freshwater would be not quite a teaspoon of that. (For all you metricphobes: a liter is about a quarter of a gallon, so five liters is equivalent to a gallon and a quarter - say, a jug of cider and a quart of milk, of which you only get a teaspoon of the beverage of your choice.). ...

Salt Water vs Fresh Water It would be easy to say that the difference between salt water and fresh water is all about whether there is salt in the water. While
Any one know of a machine/chemical to convert Salt water (8.8lb-9.4lb) to Fresh water (8.6lb) on a LARGE scale?? I have read several things on converting using the sun to evaporate the water, but thats only like a liter a day. I would love to find something or have something made that would convert on a lot larger scale (Gallons or hundreds of gallons/day). How much would be possibe? Even if a generator would be used continuously to do so. It doesnt need to be drinking water. Just approx the weight of FRESH WATER ...
In order to investigate the factors controlling viral abundance, 22 lakes in Quebec were surveyed. We measured viral and bacterial abundance, bacterial production, chlorophyll a, total phosphorus and DOC (dissolved organic carbon) concentrations. Regression models built with these data were compared to models based on literature data, which to date have been collected largely from marine sites. Positive empirical relationships were found between viral abundance and (1) chlorophyll a concentrations, (2) bacterial abundances, (3) bacterial production, and (4) total phosphorus concentration. There was little to no trend in the virus-to-bacteria ratio with increasing trophy. Analysis of covariance revealed significant differences between relations in marine and freshwater systems. The virus-to-bacteria ratio was significantly higher in freshwater (mode = 22.5) than marine environments (mode = 2.5), and there were significantly more bacteria per unit chlorophyll in our freshwater samples. We suggest ...
Fish poisoned by ammonia display a number of symptoms. Fish exposed to ammonia tend to move with jerky, darting movements. Depending on the level of ammonia in the water, fish might become lethargic and hang out near the bottom of the tank. You may also see signs of gill damage. You may see fish "gasping" at the surface of the water and rapidly flapping their gill covers. These symptoms are attempts by the fish to compensate for the damage to their gills.. ...
In field tests, floating devices containing the hydrogel were placed on the surface of the ocean, at a beach. As water vapor subsequently evaporated out of the salt water, tiny airborne droplets of that vapor were collected by the gel. Once the material was saturated, it was placed in a closed glass box that was left sitting in the hot sunlight.. Upon thus being heated to between 45 and 50 ºC (113 and 122 ºF), the gel released its stored fresh water in the form of vapor. That vapor condensed on the walls of the box, and was collected in liquid form. By contrast, materials like silica gel must be heated to considerably higher temperatures, typically requiring a manmade power source.. The researchers are now looking at ways of boosting the hydrogels absorption capacity even further, and of optimizing the water-harvesting process. In its current form, if used repeatedly throughout the day, the gel can produce over 10 liters (2.6 US gal) of fresh water per kilogram of material daily.. "Our ...
In this program we will learn introductory chemistry and introductory biology through the lens of aquatic ecosystems. A tiny fraction (less than 0.01%) of water on Earth is found in lakes and rivers, making our freshwater systems especially vulnerable to human impacts. An integrated knowledge of both chemistry and biology is necessary to understand how freshwater systems function, which is the first step necessary to preserve and/or restore these systems. Students will have the opportunity to earn 8 credits in general chemistry and 8 credits in general biology.
