A genus of colorless, filamentous bacteria in the family THIOTRICHACEAE whose cells contain inclusions of sulfur granules. When found in decaying seaweed beds and polluted water, its presence signals environmental degradation.
A family of colorless sulfur bacteria in the order Thiotrichales, class GAMMAPROTEOBACTERIA.
Chemical groups containing the covalent sulfur bonds -S-. The sulfur atom can be bound to inorganic or organic moieties.
Processes by which phototrophic organisms use sunlight as their primary energy source. Contrasts with chemotrophic processes which do not depend on light and function in deriving energy from exogenous chemical sources. Photoautotrophy (or photolithotrophy) is the ability to use sunlight as energy to fix inorganic nutrients to be used for other organic requirements. Photoautotrophs include all GREEN PLANTS; GREEN ALGAE; CYANOBACTERIA; and green and PURPLE SULFUR BACTERIA. Photoheterotrophs or photoorganotrophs require a supply of organic nutrients for their organic requirements but use sunlight as their primary energy source; examples include certain PURPLE NONSULFUR BACTERIA. Depending on environmental conditions some organisms can switch between different nutritional modes (AUTOTROPHY; HETEROTROPHY; chemotrophy; or phototrophy) to utilize different sources to meet their nutrients and energy requirements.
Linear polymers in which orthophosphate residues are linked with energy-rich phosphoanhydride bonds. They are found in plants, animals, and microorganisms.

Diversity and abundance of aerobic and anaerobic methane oxidizers at the Haakon Mosby Mud Volcano, Barents Sea. (1/15)

Submarine mud volcanoes are formed by expulsions of mud, fluids, and gases from deeply buried subsurface sources. They are highly reduced benthic habitats and often associated with intensive methane seepage. In this study, the microbial diversity and community structure in methane-rich sediments of the Haakon Mosby Mud Volcano (HMMV) were investigated by comparative sequence analysis of 16S rRNA genes and fluorescence in situ hybridization. In the active volcano center, which has a diameter of about 500 m, the main methane-consuming process was bacterial aerobic oxidation. In this zone, aerobic methanotrophs belonging to three bacterial clades closely affiliated with Methylobacter and Methylophaga species accounted for 56%+/-8% of total cells. In sediments below Beggiatoa mats encircling the center of the HMMV, methanotrophic archaea of the ANME-3 clade dominated the zone of anaerobic methane oxidation. ANME-3 archaea form cell aggregates mostly associated with sulfate-reducing bacteria of the Desulfobulbus (DBB) branch. These ANME-3/DBB aggregates were highly abundant and accounted for up to 94%+/-2% of total microbial biomass at 2 to 3 cm below the surface. ANME-3/DBB aggregates could be further enriched by flow cytometry to identify their phylogenetic relationships. At the outer rim of the mud volcano, the seafloor was colonized by tubeworms (Siboglinidae, formerly known as Pogonophora). Here, both aerobic and anaerobic methane oxidizers were found, however, in lower abundances. The level of microbial diversity at this site was higher than that at the central and Beggiatoa species-covered part of the HMMV. Analysis of methyl-coenzyme M-reductase alpha subunit (mcrA) genes showed a strong dominance of a novel lineage, mcrA group f, which could be assigned to ANME-3 archaea. Our results further support the hypothesis of Niemann et al. (54), that high methane availability and different fluid flow regimens at the HMMV provide distinct niches for aerobic and anaerobic methanotrophs.  (+info)

Insights into the genome of large sulfur bacteria revealed by analysis of single filaments. (2/15)

Marine sediments are frequently covered by mats of the filamentous Beggiatoa and other large nitrate-storing bacteria that oxidize hydrogen sulfide using either oxygen or nitrate, which they store in intracellular vacuoles. Despite their conspicuous metabolic properties and their biogeochemical importance, little is known about their genetic repertoire because of the lack of pure cultures. Here, we present a unique approach to access the genome of single filaments of Beggiatoa by combining whole genome amplification, pyrosequencing, and optical genome mapping. Sequence assemblies were incomplete and yielded average contig sizes of approximately 1 kb. Pathways for sulfur oxidation, nitrate and oxygen respiration, and CO2 fixation confirm the chemolithoautotrophic physiology of Beggiatoa. In addition, Beggiatoa potentially utilize inorganic sulfur compounds and dimethyl sulfoxide as electron acceptors. We propose a mechanism of vacuolar nitrate accumulation that is linked to proton translocation by vacuolar-type ATPases. Comparative genomics indicates substantial horizontal gene transfer of storage, metabolic, and gliding capabilities between Beggiatoa and cyanobacteria. These capabilities enable Beggiatoa to overcome non-overlapping availabilities of electron donors and acceptors while gliding between oxic and sulfidic zones. The first look into the genome of these filamentous sulfur-oxidizing bacteria substantially deepens the understanding of their evolution and their contribution to sulfur and nitrogen cycling in marine sediments.  (+info)

Physiological adaptation of a nitrate-storing Beggiatoa sp. to diel cycling in a phototrophic hypersaline mat. (3/15)

The aim of this study was to investigate the supposed vertical diel migration and the accompanying physiology of Beggiatoa bacteria from hypersaline microbial mats. We combined microsensor, stable-isotope, and molecular techniques to clarify the phylogeny and physiology of the most dominant species inhabiting mats of the natural hypersaline Lake Chiprana, Spain. The most dominant morphotype had a filament diameter of 6 to 8 microm and a length varying from 1 to >10 mm. Phylogenetic analysis by 16S rRNA gene comparison revealed that this type appeared to be most closely related (91% sequence identity) to the narrow (4-microm diameter) nonvacuolated marine strain MS-81-6. Stable-isotope analysis showed that the Lake Chiprana species could store nitrate intracellularly to 40 mM. The presence of large intracellular vacuoles was confirmed by fluorescein isothiocyanate staining and subsequent confocal microscopy. In illuminated mats, their highest abundance was found at a depth of 8 mm, where oxygen and sulfide co-occurred. However, in the dark, the highest Beggiatoa densities occurred at 7 mm, and the whole population was present in the anoxic zone of the mat. Our findings suggest that hypersaline Beggiatoa bacteria oxidize sulfide with oxygen under light conditions and with internally stored nitrate under dark conditions. It was concluded that nitrate storage by Beggiatoa is an optimal strategy to both occupy the suboxic zones in sulfidic sediments and survive the dark periods in phototrophic mats.  (+info)

Beggiatoa is a genus of bacteria in the order Thiotrichales. They are named after the Italian medic and botanist F. S. Beggiato. The organisms live in sulfur-rich environments. During his research in Anton de Barys laboratory of botany in 1887, Russian botanist Sergei Winogradsky found that Beggiatoa oxidized hydrogen sulfide (H2S) as an energy source, forming intracellular sulfur droplets. Winogradsky referred to this form of metabolism as inorgoxidation (oxidation of inorganic compounds). The finding represented the first discovery of lithotrophy.[2][3] Two species of Beggiatoa have been formally described: the type species Beggiatoa alba, and Beggiatoa leptomitoformis, the latter of which was only published in 2017.[4] ...

Hydrocarbon seeps are typically viewed as seafloor phenomena: with vast quantities of juicy organic molecules streaming out of the crust, sediment-hosted microbes are the primary recipients of the energetic windfall. But at particularly high-flow seeps, hydrocarbons can emerge into the bottom water, and, running the gauntlet of benthic aerobic heterotrophs, even reach the waters surface layers. A new study from Nigel Dsouza and colleagues demonstrates that these seafloor features actually result in measurable increases in surface-water microbial activity. By quantifying chlorophyll concentrations, the team shows that seafloor venting of many kinds may have a larger effect on the surface world than previously believed.. Abstract below, full paper [here].. Natural hydrocarbon seeps occur on the sea floor along continental margins, and account for up to 47% of the oil released into the oceans1. Hydrocarbon seeps are known to support local benthic productivity2, but little is known about their ...
All strains of freshwater Beggiatoa demonstrate the ability to grow heterotrophically in the presence of oxygen, yet this growth tends to be limited by the lack of catalase in Beggiatoa species. The lack of catalase is compensated for by the organisms ability to oxidize sulfide, which detoxifies metabolically-formed hydrogen peroxide in the absence of oxygen. Sulfide oxidation provides the bacteria with energy for growth on acetate, and is the sole energy source for at least one marine species. The cells are disk-shaped and are motile by a gliding motion. They can exist either as individual cells or as part of a tightly connected filament. ...
Phenotypic and phylogenetic comparisons of the generaBeggiatoa and Thioploca. Until recently, massive natural occurrence of filaments ofBeggiatoa or Thioploca spp. have been identified based solely on their characteristic morphologies by using (i) the presence (Thioploca spp.) or absence (Beggiatoa spp.) of a single sheath around multiple filaments and (ii) filament widths as the major criteria (Table 1). No strain of a wide marine Beggiatoa orThioploca sp. has been obtained in pure culture. The physiological properties of these genera can, therefore, be determined only from observations of natural populations. Such studies have revealed several metabolic similarities. These similarities include chemoautotrophic carbon metabolism (20, 24, 29, 31), sulfide oxidation (20, 25), and concentration of nitrate in the vacuolate cells at levels several-thousand-fold above ambient nitrate levels (5, 24). Teske et al. (38) described the phylogenetic position of vacuolate, unusually wideThioploca filaments ...

The paper is aimed at a methodological development of change-point detection, applicable in dentifying abrupt changes in temporal or spatial data sequences. In earlier papers we developed a method for detecting a change in the parameters of a discrete distribution, with the simultaneous estimation of the (deterministic but unknown) distribution parameters before and after the change. In this paper we not only extend this method to the case of normal distributions, but also provide a new algorithm for the iterative refining of the estimation of the change-point, based on a cleaning of mixed-up parts of the samples. The appropriate size of reduced part of the sample is analytically calculated for the case of normal distributions. This cleaning is combined with our original change-point detection method. Our new algorithm is not only validated on artificial data, but also applied to a real environmental data set collected and analysed by other authors in a seafloor observatory. Our ...

Håkon Mosby Mud Volcano (HMMV, SW Barents Sea slope, 1280 m) is one of the numerous cold methane-venting seeps existing along the continental margins. Analyses of videoguided core samples revealed extreme differences in the diversity and density of the metazoan meiobenthic communities associated with the different sub-habitats (centre, microbial mats, Pogonophora field, outer rim) of this mud volcano. Diversity was lowest in the sulphidic, microbial mat sediments that supported the highest standing stock, with unusually high densities (11 000 ind. 10 cm-2) of 1 nematode species related to Geomonhystera disjuncta. Stable carbon isotope analyses revealed that this nematode species was thriving on chemosynthetically derived food sources in these sediments. Ovoviviparous reproduction has been identified as an important adaptation of parents securing the survival and development of their brood in this toxic environment. The proliferation of this single species in exclusive association with ...

NNaval Special Warfare requires a low-power, light-weight acoustic intercept receiver capable of detecting and identifying the acoustic signals of manned or unmanned undersea vehicles. Traditional acoustic receivers in use on current submarine platforms are large, cumbersome and feature-rich. The Special Warfare vehicles require a much smaller, self-contained system without all the submarines capabilities. This system must operate with higher frequency operational processing bands, operationally intuitive operator / machine interface (OMI) that function under extreme in-water situations. Signal Processing must achieve high sensitivity with low false alarm rates requiring full spectrum, spectral redundant based signal processing techniques be considered to enhance detection and bearing estimates within limited space/ weight/ volume allocations. Partnered with Pennsylvania State University, our solution leverages acoustic previous acoustic intercept experience to design a low risk, operationally ...

Termo Records I remember once as a young man when I practised the noble art of rock-journalism, I went to a small gathering held by the rock magazine I was writing for. Norwegian The Last James and a Scottish pop band that I dont remember the name of was on the bill. The Last James (they had cunningly loaned their name from the by now newly deceased German orchestra leader James Last...) was fronted by Lars Pedersen, well-known as a member of the avant-exploring new wave band Holy Toy and his solo alter-ego project When that he has kept going to this very day. The band had just released their second album so this must have been round 1993. By that time Last James had been augmented by very well-known Norwegian pop-poet Lars Lillo Stenberg of deLillos fame and the lesser known Haakon Ellingsen. The latter seemed young and unexperienced at the time, at least compared to the other two, but he had written five of the most excellent songs of the somewhat uneven album. The two other more profiled ...

Conventional wisdom suggests that seamounts harbour high levels of biodiversity and endemism, play important roles in marine biogeography, are hotspots of biological carbon processing, and support substantial fisheries. However, since fewer than 300 seamounts have been thoroughly sampled, these generalizations remain largely untested. This has provided the motivation for a number of seamount-focused research projects in recent years, including CenSeam, a field project within the Census of Marine Life. This issue presents some of the research output facilitated by CenSeam. Here we summarize the main findings and provide a précis of future research directions highlighted by contributors to the issue. Recent studies show that seamounts can have comparable levels of benthic diversity and endemism to continental margins, but their communities also include a distinct composition of species that can attain higher biomass. Reported geographic differentiation among seamount communities suggests limited ...

The researchers also discovered that the physical extent of these groups varied depending on the size of the organisms. Smaller animals generally stayed closer to their neighbors, forming smaller groups. Most groups were about 100-animals wide in the horizontal dimension, regardless of whether they consisted of fish, squid, or shrimp. The spacing between the animals in each group was also very consistent, each animal staying at least one body length from its nearest neighbors.. The researchers speculate that these groups, consisting of lots of similar animals spaced evenly apart, could confuse visual predators such as dolphins, which target one animal at a time. This effect has previously been observed for schools of fish surrounded by open water near the sea surface, but has never before been seen in animals within deep scattering layers, where the schools are surrounded by other schools, and there is little or no sunlight. As Benoit-Bird pointed out, Schooling was previously thought to occur ...

The anaerobic oxidation of methane (AOM) is responsible for oxidizing nearly all of the 70.3 to 85.3 Tg of methane produced in anoxic marine sediments per year globally (50). In addition to its importance in controlling greenhouse gases, AOM has implications for investigations of early life on Earth, since anaerobic methane oxidizers and methanogens comprise a methane cycle suitable for oxidant-poor, early-Earth-like environments (19). The presence of isotopically light organic carbon in the Archean Eon suggests that AOM may have been an important microbial pathway on early Earth (19).. Although the organisms responsible for AOM in marine sediments are not yet isolated in pure culture, stable carbon isotopic studies and environmental genomic studies have shown that the process relies on archaea capable of reverse methanogenesis that often form close associations with sulfate-reducing bacteria (SRB) (5, 14, 18, 21). The archaeal anaerobic methane oxidizers (ANMEs) fall into three phylogenetic ...
Optogenetics enables manipulation of biological processes with light at high spatio-temporal resolution to control the behavior of cells, networks, or even whole animals. In contrast to the performance of excitatory rhodopsins, the effectiveness of inhibitory optogenetic tools is still insufficient. Here we report a two-component optical silencer system comprising photoactivated adenylyl cyclases (PACs) and the small cyclic nucleotide-gated potassium channel SthK. Activation of this PAC-K silencer by brief pulses of low-intensity blue light causes robust and reversible silencing of cardiomyocyte excitation and neuronal firing. In vivo expression of PAC-K in mouse and zebrafish neurons is well tolerated, where blue light inhibits neuronal activity and blocks motor responses. In combination with red-light absorbing channelrhodopsins, the distinct action spectra of PACs allow independent bimodal control of neuronal activity. PAC-K represents a reliable optogenetic silencer with intrinsic ...

Fed into the three phase power method, states Dr. Gnther Wanninger. Consortium partner Prysmian Cables Methods, a former Pirelli subsidiary, supplied the babyliss pro perfect curl undersea cables. The interconnector tends to make it possible to send up to 600MW of energy from Tasmania to Victoria. nike air max 90 pas cher homme Transmission works in the opposite path as well, however, which indicates Tasmania is able to tap into the continental power grid throughout dry periods when its rivers do not contain sufficient water to fill its dams. Another benefit of HVDC systems is that they require only two cables as opposed to the three required for 3 phase current transmission. As air max 90 pas cher a outcome, an HVDC overhead line also requires much less area. Basslink is not only the worlds longest HVDC undersea cable hyperlink it also has a number of other extraordinary features. For example, semiconductor components thyristors act as energy converters, which are controlled by ten mW laser ...

The Puerto Rico Legislatures pursuit of much-needed energy reform is a commendable first step forwarded by Senate President Eduardo Bhatia and House Speaker Jaime Perelló in helping to bring down electricity rates. There is no question that Puerto Ricos astronomical electricity costs-the highest in the entire U.S. at 26¢ to 30¢ per kilowatt-hour kWh-must come…

NSFs mission is to advance the progress of science, a mission accomplished by funding proposals for research and education made by scientists, engineers, and educators from across the country.
Passive cooling is wonderful, and really drops the energy footprint of a data center, albeit a very small one which is being tested. Scaled up, I can think of another big impact: property taxes. Does anyone know what the law says about dropping a pod in the ocean? As far as I can tell, laying undersea cabling is expensive, but once installed there are no landlords holding out their hands for a monthly extraction. Rent aside, taking up space with windowless buildings sucking huge amounts of electricity isnt going to win hearts and minds of the neighborhood. Undersea real estate make sense there too.. But its fun to play Devils Advocate, and this one immediately raised my eyebrow. I read as much Sci Fi as time allows, and am always interested to see which authors are registering the best technology predictions. This is the second time in short order that I turn to [William Hertlings] work. Back in November, Google announced a project to add predictive responses to Gmail. This parallels the ...

On January 4, 1855, Mambajao was separated from Catarman, and by July 6 that year it was proclaimed as a town, with Fr. Valero Salvo as its first parish priest.[6] On July 17, 1864, tremors were felt across the town, which were signs of an ongoing activity within an undersea volcano near Catarman. By May 1, 1871, the volcano erupted, decimating the town of Catarman, which lead to almost all of its inhabitants moving to Mambajao.[6] In January 1872, Barrio Agojo was transferred from Guinsiliban to Mambajao.[6] The towns principal crop in the 19th century was abaca, while coffee and cacao were mostly produced for local consumption.[6] Sporadic fires were started from April 13, 1865 until 1881 by people attempting to burn down the town.[6] By the 1880s, the town had become cosmopolitan, for its population then included Spaniards, Tagalogs, Cebuanos, Leyteños, Samareños, Ilocanos, and others in addition to Camigueños and Boholanos.[6] In 1942, the Japanese forces landed in the town of Mambajao. ...
Although the vast majority of life on Earth lives in mesophyllic (moderate) environments, a few organisms, most of them microbes, have managed to colonise extreme environments that are unsuitable for most higher life forms. There are bacteria, for example, living in Lake Whillans, half a mile below the ice of Antarctica; in the absence of sunlight, they must rely on organic material from elsewhere, perhaps decaying matter from glacier melt water or minerals from the underlying rock.[25] Other bacteria can be found in abundance in the Mariana Trench, the deepest place in the ocean and on Earth; marine snow drifts down from the surface layers of the sea and accumulates in this undersea valley, providing nourishment for an extensive community of bacteria.[26]. Other microbes live in habitats lacking in oxygen, and are dependent on chemical reactions other than photosynthesis. Boreholes drilled 300 m (1,000 ft) into the rocky seabed have found microbial communities apparently based on the products ...
The heart of this extraordinary receiver was an ingenious ultrasound system for modulating the light scanned onto the screen. This type of optical diffraction cell seems to have been devised simultaneously in 1932 by the American team of Debye and Sears; and by the French scientists Lucas and Biquard. However its full practical application to light modulation in television is due to J H Jeffree, the chief engineer of the British firm, Scophony Limited. Formed in 1930 by Solomon Sagall, Scophonys main emphasis lay in developing novel methods of mechanical TV scanning to produce large screen images. J H Jeffree championed the usage of ultrasonic light modulators for this purpose, as a result of which this modulator became known, at least in the late 1930s, as The Jeffree Cell. In this TV application, the cell was lengthened to act as a sort of ultrasonic/optical delay line. As the ultrasound modulated by the incoming video signal travelled along the liquid in the cell, the device optically ...
Two miles below the surface of the ocean, researchers from the University of Hawaii at Mānoa and colleagues discovered new microbes that breathe sulfate -- that is, gain energy by reacting sulfate with organic (carbon-containing) compounds.. The microbes, which have yet to be classified and named, exist in massive undersea aquifers -- networks of channels in porous rock beneath the ocean where water continually churns. About one-third of the Earths biomass is thought to exist in this largely uncharted environment.. Using DNA sequencing, a team of UH Mānoa researchers has spent the last few years accumulating strong evidence that this area of the deep subsurface harbors unique microorganisms. Its a massive biome dominated by microbes that scientists know very little about. Thats what makes this recent work exciting - while we suspected it in the past, we now have DNA sequence data linking sulfate reduction to some of these new and novel microorganisms, said Michael Rappé, associate ...

Any other very talked-about dive is situated close to Plymouth, the place the ruin of the steamship Maine discovered its ultimate resting position. It may be discovered roughly a mile off Bolt Head. It was once extremely noticeable for a lot of years, because the masts of the send broke the outside of the water. The ruin has since been cleared of its mast, with many of the particles swept to its port facet. It rests in water this is roughly 30 meters deep. The send was once torpedoed in March of 1917 and, after a noble rescue effort, got here to relaxation in waters inside of simple succeed in from Salcombe. Whilst this could be a great exploration for any diver, its not really useful for beginner divers because of the robust present.

The objective of the HOTPLUME project is to improve understanding of the spatial and temporal dynamics of deep hydrothermal systems and determine the importance of hydrothermal gases relating to mineral resources and to what extent they are involved in major biogeochemical cycles.. Over the past decade, the need for a tool to explore vast distances of the deep oceans has led to the development of autonomous undersea platforms such as AUVs. Combined with appropriate in-situ chemical sensors, they are able not only to detect the presence of hydrothermal activity with considerable precision but also to measure the flows within rising and steady-state hydrothermal plumes and map the distribution of gases within the plume.. HOTPLUME will involve equipping AUVs with an in-situ mass spectrometer to quantify gas concentrations and flow and determine the chemical, physical and potentially biological processes controlling the behaviour and future of the gases dissolved in the plumes.. The resulting ...
