Gammaproteobacteria is a class of Gram-negative bacteria comprising 17 orders and plays an important role in crop and animal health in various soil microbiomes (1, 2). Although their universal distribution and prevalence in the soil environment are revealed by 16S rRNA gene amplicon sequencing and shotgun metagenomic sequencing, most of them remain uncultivated at this time (3). Therefore, an expansion of the reference genomes of Gammaproteobacteria would lead to an improved understanding of their genetic diversity and relationship with the environment and other microbial species. In our present study, we sequenced two uncultivated strains of Gammaproteobacteria using the single-cell genome sequencing platform bit-MAP, originally named SAG-gel (4).. Soil sampling was conducted in two strawberry cultivation greenhouses before harvest in December 2019 (Okawa, Fukuoka, Japan). A total of 20 g of soil sample was collected at a depth of 5 to 10 cm around the seedlings. To extract the bacterial ...

A denitrifying bacterium, designated strain FS T , was isolated from anoxic digested sludge on oestradiol [17 β -oestra-1,3,5(10)-triene-3,17-diol] or testosterone (17 β -hydroxyandrost-4-en-3-one) as the sole source of carbon and energy with nitrate as
INTRODUCTION TO THE GAMMAPROTEOBACTERIA. The Gammaproteobacteria is a large, diverse group that includes some of the most important microbial organisms (e.g. Escherichia, Enterobacter, Francisella, Pasteurella). By and large, all organisms in this phylum are unicellular, and most are rods. The phylum is defined by two major groups one photoautotrophic and the other heterotrophic. The purple sulfur bacteria (Figures 1 and 2) are obligate anaerobes that utilize bacteriochlorophylls to capture light energy for photosynthetic pathways in which carbon dioxide is fixed into organic molecules. The electrons are provided by hydrogen sulfide rather than water as in the plants. Usually they occur in environments where the conditions of anoxia and light both occur. This can be seen in particular clear lakes with anoxic bottom layers. In such conditions, anaerobic photosynthetic bacteria can be very abundant.. The other great group tends to be heterotrophic and aerobic or facultatively anaerobic. It ...

The marine bacterium Halomonas titanicae strain BH1 was isolated from a sample of rusticles, which are formed in part by a consortium of microorganisms, collected from the RMS Titanic wreck site (1). This bacterium was previously characterized as a new species of the genus Halomonas, which includes a large number of species isolated predominantly from marine, hypersaline, or alkaline habitats (saline lakes, salterns, salted food, etc.). Although these species are easily isolated from saline and hypersaline environments, genome data are currently available only from the type species of the genus Halomonas, H. elongata (2). Halomonas titanicae is a Gram-negative, heterotrophic, aerobic rod, motile by peritrichous flagella. Phylogenetically this organism belongs to the Gammaproteobacteria within the family Halomonadaceae (3, 4). This halophilic organism has a respiratory metabolism, being able to grow in media with 0.5 to 25% NaCl (optimal growth at 2 to 8% NaCl); no growth occurs in the absence of ...

2-Oxocarboxylic acids, also called 2-oxo acids and alpha-keto acids, are the most elementary set of metabolites that includes pyruvate (2-oxopropanoate), 2-oxobutanoate, oxaloacetate (2-oxosuccinate) and 2-oxoglutarate. This diagram illustrates the architecture of chain extension and modification reaction modules for 2-oxocarboxylic acids. The chain extension module RM001 is a tricarboxylic pathway where acetyl-CoA derived carbon is used to extend the chain length by one. The chain modification modules RM002 (including RM032) and RM033, together with a reductive amination step (RC00006 or RC00036), generate basic and branched-chain amino acids, respectively. The modification module RM030 is used in the biosynthesis of glucosinolates, a class of plant secondary metabolites, for conversion to oxime followed by addition of thio-glucose moiety. Furthermore, the chain extension from 2-oxoadipate to 2-oxosuberate is followed by coenzyme B biosynthesis in methonogenic archaea ...

Adults inhabit shallow coastal waters with rocky substrate. They are found under overhanging rocks, entrances of caves and other biotopes with reduced light. In the Atlantic, they occur in shallow, light-exposed biotopes. They feed on benthic invertebrates, also on harpacticoids (Ref. 4785), amphipods and other copepods (Ref. 94105). Males court by figure-8-swimming (Ref. 4785). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114). ...

Members of Vibrionaceae (Gammaproteobacteria: Vibrionales) have been known since 1854 (Pacini) and were shown to be distinct much before pulsed-field gel electrophoresis revealed the most distinct diagnostic morphological feature, the existence of two chromosomes [1]. The interest in these bacteria is not surprising given that several species are pathogenic to humans and marine organisms and others are bioluminescent symbionts of marine fishes and squids e.g.[2-7]. Some lesser-known species are psychrophiles (live in cold temperatures), piezophiles (live at high pressures), or halophiles (live at high NaCl concentration; [8]). The diversity of ecologies represented by members of Vibrionaceae has led to enthusiastic genome sequencing in the group, which has focused most heavily on pathogenic species (more than 31 strains of V. cholerae are available on GenBank as of 2012).. A phylogenetic hypothesis based on complete genomes was desired for Vibrionaceae. While the analysis presented in [9] for ...
The Synodontidae or lizardfishes[note 1] are benthic (bottom-dwelling) marine and estuarine bony fishes that belong to the aulopiform fish order, a diverse group of marine ray-finned fish consisting of some 15 extant and several prehistoric families. They are found in tropical and subtropical marine waters throughout the world. Lizardfishes are generally small, although the largest species measures about 60 cm (24 in) in length. They have slender, somewhat cylindrical bodies, and heads that superficially resemble those of lizards. The dorsal fin is located in the middle of the back, and accompanied by a small adipose fin placed closer to the tail.[2] They have mouths full of sharp teeth, even on the tongue.[1] Lizardfishes are benthic animals that live in shallow coastal waters; even the deepest-dwelling species of lizardfish live in waters no more than 400 m (1,300 ft) deep. Some species in the subfamily Harpadontinae live in brackish estuaries. They prefer sandy environments, and typically ...
When the gonads are mature, the pineal ruptures and sperm are released into the sea. The eggs are cemented to the outer walls of the pinnules, where they are fertilised.. The larvae that develops is barrel shaped (doliolaria larvae) and does not feed. It lives as a free swimming form for a short time, before it develops into a sessile stalked form called a pentacrinoid larvae. In this form it feeds and grows for several months, before becoming an adult.. Though many of the free living crinoidea are found in shallow coastal waters, the stalked forms are normally only found in waters deeper than 100 metres.. Crinoids can be divided into two different types, depending on their feeding strategy: whether they like moving water or not.. Those that do like moving water are called rheophilic (current seeking) and those that do not are called rheophobic (current avoiding or fearing).. Rheophilic forms are more common. These forms may hide in a cavity during the day and emerge at night - using the cirri ...

HIMOM project will establish a prototype of a standard and validated set of hierarchically organized monitoring tools for shallow coastal waters and in particular estuaries, which enables local authorities and European agencies to compare the results of coastal monitoring programs. Depending on the level of methods, to be selected from the hierarchical toolbox, answers on different levels of complexity about the monitored area can be derived and compared. Pigments of the phythobenthos of intertidal flats play a key role in the proposed monitoring system. They are used as an index for biomass and biodiversity, because they are available everywhere during the vegetation period. Their regional and temporal variations will be used as an indicator of the systems response to human and natural interference (eutrophication, fisheries, dredging, flooding). Remote sensing expands the regional and temporal observation network, and algorithm development for interpretation of images from airplanes and ...
Gammaproteobacteria belonging and related to the genus Microbulbifer are an emerging group of complex carbohydrate-degrading marine bacteria. Previously, all of the representatives were placed within Microbulbifer or were unclassified. Recently, a new genus, Teredinibacter, represented by a single species, Teredinibacter turnerae, was formed to include an endosymbiotic branch of these organisms. In this study, based on 16S rRNA gene sequence similarity and phenotypic analyses, a new genus, Saccharophagus, is proposed to accommodate the most versatile marine carbohydrate degrader yet identified, Saccharophagus degradans gen. nov., sp. nov. 2-40(T) (=ATCC 43961(T)=DSM 17024(T)). S. degradans strain 2-40(T) can degrade 10 tested complex polysaccharides: agar, alginate, chitin, cellulose, fucoidan, laminarin, pectin, pullulan, starch and xylan. S. degradans 2-40(T) shares 90.5% 16S rRNA gene sequence similarity with the type strain of the Microbulbifer type species, Microbulbifer hydrolyticus ...
Chemoautotrophic symbioses, in which endosymbiotic bacteria are the major source of organic carbon for the host, are found in marine habitats where sulfide and oxygen coexist. The purpose of this study was to determine the influence of pH, alternate sulfur sources, and electron acceptors on carbon fixation and to investigate which form(s) of inorganic carbon is taken up and fixed by the gamma-proteobacterial endosymbionts of the protobranch bivalve Solemya velum. Symbiont-enriched suspensions were generated by homogenization of S. velum gills, followed by velocity centrifugation to pellet the symbiont cells. Carbon fixation was measured by incubating the cells with (14)C-labeled dissolved inorganic carbon. When oxygen was present, both sulfide and thiosulfate stimulated carbon fixation; however, elevated levels of either sulfide (|0.5 mM) or oxygen (1 mM) were inhibitory. In the absence of oxygen, nitrate did not enhance carbon fixation rates when sulfide was present. Symbionts fixed carbon most rapidly
Pectinatella magnifica, an invasive bryozoan, might significantly affect ecosystem balance due to its massive occurrence in many areas in Europe and other parts of the world. Biological and chemical analyses are needed to get complete information about the impact of the animal on the environment. In this paper, we aimed to evaluate in vitro cytotoxic effects of five extracts prepared from P. magnifica using LDH assay on THP-1 cell line. Antimicrobial activities of extracts against 22 different bacterial strains were tested by microdilution method. Our study showed that all extracts tested, except aqueous portion, demonstrated LD50 values below 100 μg/mL, which indicates potential toxicity. The water extract of P. magnifica with LD50 value of 250 μg/mL also shows potentially harmful effects. Also, an environmental risk resulting from the presence and increasing biomass of potentially toxic benthic cyanobacteria in old colonies should not be underestimated. Toxicity of Pectinatella extracts could be
Given the phylogenetic similarity between the stinkbug symbionts and Buchnera, the researchers wondered whether their biology might be similar as well. They divided egg masses into two groups and deprived one group of capsules to generate sibling populations with and without gut symbionts. Adults lacking symbionts showed developmental delays, grew smaller, failed to copulate or reproduce, and died prematurely. Like aphids depend on their endosymbionts, plataspid stinkbugs depend on their gut symbionts to survive how they do this, however, will be interesting to discover. Like Buchnera, the gut endosymbionts also appear to have co-evolved with their host. The phylogenetic tree of the stinkbugs, the researchers found, perfectly agreed with the phylogenetic relationships of the gut symbionts. Maternal transmission of the symbiont capsule provides a means of stable transmission, but other factors such as physiological compatibility may come into play ...
Recent studies suggest that unidentified prokaryotes fix inorganic carbon at globally significant rates in the immense dark ocean. Using single-cell sorting and whole-genome amplification of prokaryotes from two subtropical gyres, we obtained genomic DNA from 738 cells representing most cosmopolitan lineages. Multiple cells of Deltaproteobacteria cluster SAR324, Gammaproteobacteria clusters ARCTIC96BD-19 and Agg47, and some Oceanospirillales from the lower mesopelagic contained ribulose-1,5-bisphosphate carboxylase-oxygenase and sulfur oxidation genes. These results corroborated community DNA and RNA profiling from diverse geographic regions. The SAR324 genomes also suggested C1 metabolism and a particle-associated life-style. Microautoradiography and fluorescence in situ hybridization confirmed bicarbonate uptake and particle association of SAR324 cells. Our study suggests potential chemolithoautotrophy in several uncultured Proteobacteria lineages that are ubiquitous in the dark oxygenated ...
Psychrobacter is a genus within the gamma-proteobacteria. These bacteria live in extremely cold habitats, such as Antarctic ice, soil, and sediments, as well as in deep sea environments. One species, Psychrobacter cryohalolentis, has been isolated from samples of Siberian permafrost, where temperatures are typically 9º-11º C. Researchers have been able to use these strains to learn more about the evolution and response of bacteria when exposed to extremely low temperatures. Psychrobacter have also been found in various food sources, including poultry, fish, and meat products. While little is known about species of Psychrobacter in humans, Psychrobacter immobilus has been isolated from sources such as the eye, brain tissue, urethra, cerebral spinal fluid, and blood, leading some scientists to suspect that these bacteria may be the cause of opportunistic infections in some patients. The clinical manifestation of this species is virtually unknown, although it has been isolated in patients with ...
ABSTRACT: Halocynthia roretzi (phylum Cordata), also called sea pineapples, live in shallow coastal waters and typically feed on plankton and detritus that they filter from seawater. It has been reported that symbiotic microflora associated with H. roretzi act as protective agents that strengthen its immune system or control energy metabolism. This study analyzed the culturable microflora from the coelomic fluid of the sea pineapple using MALDI-biotyping and 16S rRNA sequencing, combining a recent technology with the conventional method of bacteria identification. The MALDI-biotyper enabled the classification of the symbiotic microflora into 5 groups based on the specific patterns of their mass spectrum. The 16S rRNA sequencing was then used to establish the identity of the dominant bacteria in 4 groups, later revealed as 2 groups of Vibrio spp., Shwanella spp. and Bacillus spp. MALDI-biotyping was applied for the identification of microorganisms directly from cultured agar, and, coupled with ...
The relationship between the Hawaiian bobtail squid and the bioluminescent bacteria living in its light organ has been studied for decades as a model of symbiosis. Now researchers have used a powerful chemical analysis tool to identify a small molecule produced by the bacteria that appears to play an important role in their colonization of the light organ.. The study, published March 9 in the journal mBio, adds a new wrinkle to scientists understanding of the chemical signaling involved in this iconic symbiotic relationship. Its exciting that there are still new things to discover, even in such a well-studied system, said corresponding author Laura Sanchez, associate professor of chemistry and biochemistry at UC Santa Cruz.. The Hawaiian bobtail squid is a small nocturnal squid, about the size of a thumb, that lives in shallow coastal waters, hiding in the sand during the day and coming out at night to hunt for small shrimp and other prey. The bioluminescent glow from its light organ is ...
This isnt science fiction. Its happening now in a lab inside Virginia Techs Durham Hall, where a 600-gallon tank is regularly filled with water as small robotic jellyfish are tested for movement and energy self-creation and usage. A synthetic rubbery skin, squishy in ones hand, mimics the sleek jellyfish skin and is placed over a bowl-shaped device covered in electronics. When moving, they look weirdly alive.. The robotic creatures are called RoboJelly are being designed to operate on their own energy versus, say, sea crabs, or mollusks.. Jellyfish are attractive candidates to mimic because of their ability to consume little energy owing to a lower metabolic rate than other marine species, survivability in varying water conditions, and possession of adequate shape for carrying a payload, Priya said. They inhabit every major oceanic area of the world and are capable of withstanding a wide range of temperatures and in fresh and salt waters. Most species are found in shallow coastal waters, ...
Genes for the RNA tmRNA and protein SmpB, partners in the trans-translation process that rescues stalled ribosomes, have previously been found in all bacteria and some organelles. We validate recent identification of tmRNA homologs in oomycete mitochondria by finding partner genes from oomycete nuclei that target SmpB to the mitochondrion. Exhaustive search now identifies a small number of complete, often highly derived, bacterial genomes that appear to lack a functional copy of one or the other partner gene (but not both). Three groups with reduced genomes have lost the central loop of SmpB, which is thought to improve alanylation and EF-Tu activation: Carsonella, Hodgkinia and the hemplasmas (hemotropic Mycoplasma). Carsonella has also lost the SmpB C-terminal tail, thought to stimulate the decoding center of the ribosome. Carsonella moreover exhibits gene overlap such that tmRNA maturation should produce a non-stop smpB mRNA, and one isolate exhibits complete degradation of the tmRNA gene yet ...

A moderately salt-tolerant and obligately alkaliphilic, chemolithoautotrophic sulfur-oxidizing bacterium, strain HL-EbGr7T, was isolated from a full-scale bioreactor removing H2S from biogas under oxygen-limited conditions. Another strain, ALJ17, closely related to HL-EbGr7T, was isolated from a Kenyan soda lake. Cells of the isolates were relatively long, slender rods, motile by a polar flagellum. Although both strains were obligately aerobic, micro-oxic conditions were preferred, especially at the beginning of growth. Chemolithoautotrophic growth was observed with sulfide and thiosulfate in a pH range of 8.0-10.5 (optimum at pH 10.0) and a salinity range of 0.2-1.5 M total Na+ (optimum at 0.4 M). The genome sequence of strain HL-EbGr7T demonstrated the presence of genes encoding the reverse Dsr pathway and a truncated Sox pathway for sulfur oxidation and enzymes of the Calvin-Benson cycle of autotrophic CO2 assimilation with ribulose-bisphosphate carboxylase/oxygenase (RuBisCO) type I. The dominant
A novel aerobic, Gram-negative bacterium, designated strain CM41_15aT, was isolated from the surface of coastal waters of the north-western Mediterranean Sea. Cells were non-motile straight rods that formed red colonies on marine agar medium. The G+C content of the genomic DNA was 65 mol %. Phylogenetic analysis of the 16S rRNA gene sequence placed the strain in the genus Haliea within the class Gammaproteobacteria. On the basis of the 16S rRNA gene sequence comparison and physiological and biochemical characteristics, strain CM41_15aT represents a novel species, for which the name Haliea rubra sp. nov. is proposed. The type strain is CM41_15aT (=DSM 19751T=CIP 109758T=MOLA 104T).
Satellite remote sensing is an advanced tool used to characterize seagrass biomass and monitor changes in clear to less-turbid waters by analyzing multi-temporal satellite images. Seagrass information was extracted from the multi-temporal satellite datasets following a two-step procedure: (i) retrieval of substrate-leaving radiances; and (ii) estimation of seagrass total aboveground biomass (STAGB). Firstly, the substrate leaving radiances is determined by compensating the water column correction of the pre-processed data because of the inherent errors associated with the geometric and radiometric fidelities including atmospheric perturbations. Secondly, the seagrass leaving radiances were correlated to the corresponding in situ STAGB to predict seagrass biomass. The relationship between STAGB and cover percentage was then established for seagrass meadows occurring in Merambong, Straits of Johor, Malaysia. By applying the above-mentioned approach on Landsat Thematic Mapper (TM) acquired in 2009 and
Previously, we reported that recA was probably lost in the early stage of RGE in Calyptogena clam symbionts [8]. The present study showed that some of the extant clam symbionts still have intact recA (Figure 2). We hypothesized that in the early phase of RGE of the clam symbionts before the loss of recA, large-sized deletions occurred due to RecA-dependent recombination [8]. This type of deletion requires repeated sequences larger than 200 bp, which have been depleted from the genomes of Rma and Vok [8, 19]. It is still not clear whether the genomes of the Calyptogena clam symbionts containing recA have large-sized (, 200 bp) repeated sequences. The presence of intact or of nearly intact recA and of mutY in clade II symbionts except for Rma suggests that the genomes of clade II symbionts are larger than those of clade I symbionts and that their RGE is in an earlier stage than in clade I symbionts. To resolve these questions, we must await their genome sequence analyses.. The coding region of ...

Abstract A new ridgewayiid copepod, Stygoridgewayia trispinosa n. g. and n. sp., is described from continental ground waters of the Cape Range Peninsula and Pilbara regions of Western Australia, as the first occurrence of this family in fresh waters. The new genus can be distinguished from other ridgewayiid genera by a combination of characters that include three digitiform processes and striated membrane on each caudal ramus, fused ancestral segments II-IV and V-VI on the antennary exopod, leg 1 with a subterminal flagellum on the outer spiniform setae of the terminal exopodal segment, legs 3 and 4 with two outer spiniform setae on the terminal exopodal segment, and female leg 5 with reduced armature on the exopod, terminal exopodal segment inserted along the distal margin of the middle exopodal segment, and endopod absent. We postulate that this new ridgewayiid is a particle feeder living in close contact with the sediment surface, and originated in shallow coastal waters and secondarily colonized the
2017, Springer Science+Business Media B.V. Seagrasses are a diverse group of angiosperms that evolved to live in shallow coastal waters, an environment regularly subjected to changes in oxygen, carbon dioxide and irradiance. Zostera muelleri is the dominant species in south-eastern Australia, and is critical for healthy coastal ecosystems. Despite its ecological importance, little is known about the pathways of carbon fixation in Z. muelleri and their regulation in response to environmental changes. In this study, the response of Z. muelleri exposed to control and very low oxygen conditions was investigated by using (i) oxygen microsensors combined with a custom-made flow chamber to measure changes in photosynthesis and respiration, and (ii) reverse transcription quantitative real-time PCR to measure changes in expression levels of key genes involved in C4 metabolism.

Where did this copy of AS originate from? It aligned well with the version of AS from P. aeruginosa and appeared to have a bacterial origin but was not found on the C. ruddii genome or the psyllid mitochondrial genome, both of which have been sequenced. Several lines of evidence ruled out the presence of a second bacterial endosymbiont in this symbiosis and since no plasmids had been reported during DNA sequencing of C. ruddii the source of this sequence appeared to be the nuclear genome of P. venusta itself. The presence of this bacterial sequence in the eukaryotic genome suggests that LGT may have taken place between a bacterial genome and the insect nuclear genome. This would be one explanation for the fact that C. ruddii has only 182 ORFs, which is significantly lower than the predicted minimal bacterial genome. However, it is also possible that C. ruddii uses mitochondrial proteins to survive and so LGT is not the only explanation for the low ORF count. ...

Bedbugs are so five minutes ago. Theres a new intruder infesting the Middle Atlantic states: the stinkbug. Seeking warmth for the winter, theyre crawling into homes, offices and hotels, and hitching rides in trucks, buses, even your handbag.
Although its existence has been known for centuries thanks to fossil records, scientists have for the first time found a living giant shipworm.
