Roseovarius tolerans gen. nov., sp. nov., a budding bacterium with variable bacteriochlorophyll a production from hypersaline Ekho Lake. (1/358)

Eight Gram-negative, aerobic, pointed and budding bacteria were isolated from various depths of the hypersaline, heliothermal and meromictic Ekho Lake (Vestfold Hills, East Antarctica). The cells contained storage granules and daughter cells could be motile. Bacteriochlorophyll a was sometimes produced, but production was repressed by constant dim light. The strains tolerated a wide range of temperature, pH, concentrations of artificial seawater and NaCl, but had an absolute requirement for sodium ions. Glutamate was metabolized with and without an additional source of combined nitrogen. The dominant fatty acid was C18:1; other characteristic fatty acids were C18:2, C12:0 2-OH, C12:1 3-OH, C16:1, C16:0 and C18:0. The main polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine. The DNA G+C base composition was 62-64 mol%. 16S rRNA gene sequence comparisons showed that the isolates were phylogenetically close to the genera Antarctobacter, 'Marinosulfonomonas', Octadecabacter, Sagittula, Sulfitobacter and Roseobacter. Morphological, physiological and genotypic differences to these previously described and distinct genera support the description of a new genus and a new species, Roseovarius tolerans gen. nov., sp. nov. The type strain is EL-172T (= DSM 11457T).  (+info)

Rubrimonas cliftonensis gen. nov., sp. nov., an aerobic bacteriochlorophyll-containing bacterium isolated from a saline lake. (2/358)

Phenotypic and phylogenetic studies were performed with two strains (OCh 317T and OCh 318; T = type strain) of aerobic chemoheterotrophic bacteriochlorophyll-containing bacteria isolated from water of a saline lake located on the west coast of Australia. Both strains were Gram-negative, short rods and were motile by means of polar flagella. Catalase, oxidase, nitrate reductase, phosphatase and urease were produced. The cells utilized D-glucose, citrate, glycolate, pyruvate and ethanol. Acids were produced from L-arabinose, D-fructose, D-galactose, D-glucose, D-ribose and D-xylose. The strains could grow in media containing 0.5-7.5% NaCl. Bacteriochlorophyll a was synthesized under aerobic conditions. The results of 16S rRNA gene sequence comparisons revealed that strain OCh 317T represented a new lineage in the alpha-3 group of the class Proteobacteria. Strains OCh 317T and OCh 318 were identified as strains of the same species because of their very similar phenotypic characteristics and their previously described high DNA-DNA homology. Therefore, it was concluded that the two strains should be assigned to a new genus and species, for which the name Rubrimonas cliftonensis is proposed. The type strain is OCh 317T (= JCM 10189T).  (+info)

Multiple pathways for ultrafast transduction of light energy in the photosynthetic reaction center of Rhodobacter sphaeroides. (3/358)

A pathway of electron transfer is described that operates in the wild-type reaction center (RC) of the photosynthetic bacterium Rhodobacter sphaeroides. The pathway does not involve the excited state of the special pair dimer of bacteriochlorophylls (P*), but instead is driven by the excited state of the monomeric bacteriochlorophyll (BA*) present in the active branch of pigments along which electron transfer occurs. Pump-probe experiments were performed at 77 K on membrane-bound RCs by using different excitation wavelengths, to investigate the formation of the charge separated state P+HA-. In experiments in which P or BA was selectively excited at 880 nm or 796 nm, respectively, the formation of P+HA- was associated with similar time constants of 1.5 ps and 1. 7 ps. However, the spectral changes associated with the two time constants are very different. Global analysis of the transient spectra shows that a mixture of P+BA- and P* is formed in parallel from BA* on a subpicosecond time scale. In contrast, excitation of the inactive branch monomeric bacteriochlorophyll (BB) and the high exciton component of P (P+) resulted in electron transfer only after relaxation to P*. The multiple pathways for primary electron transfer in the bacterial RC are discussed with regard to the mechanism of charge separation in the RC of photosystem II from higher plants.  (+info)

Kinetics of photoacclimation in cultures of Chromatium vinosum DSM 185 during shifts in light irradiance. (4/358)

Continuous cultures of Chromatium vinosum DSM 185 were shifted from a high to a low irradiance (67 to 4 microE m(-2) s(-1)) and vice versa (4 to 67 microE m(-2) s(-1)). The kinetics of photoacclimation of the cultures were analysed during these transitions until steady state was reached. When irradiance was shifted from 4 to 67 microE m(-2) s(-1), bacteriochlorophyll synthesis halted for 4 h. During this period, pigments were progressively diluted in the newly formed biomass, resulting in a lower specific pigment content. The specific growth rate of the organisms did not change immediately after the shift, but rather underwent a gradual increase during the following 10 h. This transition was accompanied by a transient increase in the levels of glycogen, indicating that CO2 fixation rates increased immediately after the shift, and that unused photosynthate was stored as glycogen. The shift from a high to a low irradiance was characterized by an immediate drop in the specific growth rate to virtually zero, and by comparatively sharp decreases in the specific rates of sulfur and sulfide oxidation and in the specific rate of glycogen accumulation. The specific content of bacteriochlorophyll a increased during the first 10 h. During the same period the specific content of glycogen decreased.  (+info)

Roseateles depolymerans gen. nov., sp. nov., a new bacteriochlorophyll a-containing obligate aerobe belonging to the beta-subclass of the Proteobacteria. (5/358)

Strains 61AT (T = type strain) and 61B2, the first bacteriochlorophyll (BChl) a-containing obligate aerobes to be classified in the beta-subclass of the Proteobacteria, were isolated from river water. The strains were originally isolated as degraders of poly(hexamethylene carbonate) (PHC). The organisms can utilize PHC and some other biodegradable plastics. The strains grow only under aerobic conditions. Good production of BChl a and caroterioid pigments is achieved on PHC agar plates and an equivalent production is observed under oligotrophic conditions on agar medium. Spectrometric results suggest that BChl a is present in light-harvesting complex I and the photochemical reaction centre. The main carotenoids are spirilloxanthin and its precursors. Analysis of the 16S rRNA gene sequence indicated that the phylogenetic positions of the two strains are similar to each other and that their closest relatives are the genera Rubrivivax, ideonella and Leptothrix with similarities of 96.3, 96.2 and 96.1%, respectively. The cells are motile, straight rods and contain poly-beta-hydroxybutyrate granules. Ubiquinone-8 is the predominant quinone. Vitamins are not required for growth. The G + C content of genomic DNA is 66.2-66.3 mol%. Genetic and phenotypic features suggest that the strains represent a new genus in the beta-subclass which is evenly distant from known genera. Consequently, the name Roseateles depolymerans gen. nov., sp. nov. is proposed for the strains; the type strain of Roseateles depolymerans is strain 61AT (= DSM 11813T).  (+info)

Roseivivax halodurans gen. nov., sp. nov. and Roseivivax halotolerans sp. nov., aerobic bacteriochlorophyll-containing bacteria isolated from a saline lake. (6/358)

Phenotypic and phylogenetic studies were performed with two strains (OCh 239T and OCh 210T, T = type strain) of aerobic bacteriochlorophyll-containing bacteria isolated from the charophytes and the epiphytes on the stromatolites, respectively, of a saline lake located on the west coast of Australia. Both strains were chemoheterotrophic, Gram-negative and motile rods with subpolar flagella. Catalase and oxidase were produced. ONPG reaction was positive. Cells utilized D-glucose, acetate, butyrate, citrate, DL-lactate, DL-malate, pyruvate, succinate, L-aspartate and L-glutamate. Acids were produced from D-fructose and D-glucose. Bacteriochlorophyll a was synthesized under aerobic conditions. Strain OCh 239T had nitrate reductase and phosphatase. Acids were produced from L-arabinose, D-galactose, lactose, maltose, D-ribose and sucrose. The strain could grow in 0-20.0% (w/v) NaCl. Strain OCh 210T had urease. Hydrolysis of gelatin was positive. Acids were produced from D-xylose. The strain could grow in 0.5-20.0% (w/v) NaCl. The results of 16S rRNA sequence comparisons revealed that strains OCh 239T and OCh 210T formed a new cluster within the alpha-3 group of the alpha subclass of the class Proteobacteria. The similarity value of the 16S rRNA sequences between strains OCh 239T and OCh 210T was 95.8%. Therefore, it was concluded that these two strains should be placed in a new genus, Roseivivax gen. nov., as the new species Roseivivax halodurans sp. nov. and Roseivivax halotolerans sp. nov. The type species of the genus is Roseivivax halodurans. The type strains of Roseivivax halodurans and Roseivivax halotolerans are OCh 239T (= JCM 10272T) and OCh 210T (= JCM 10271T), respectively.  (+info)

Thiorhodospira sibirica gen. nov., sp. nov., a new alkaliphilic purple sulfur bacterium from a Siberian soda lake. (7/358)

A new purple sulfur bacterium was isolated from microbial films on decaying plant mass in the near-shore area of the soda lake Malyi Kasytui (pH 9.5, 0.2% salinity) located in the steppe of the Chita region of south-east Siberia. Single cells were vibrioid- or spiral-shaped (3-4 microns wide and 7-20 microns long) and motile by means of a polar tuft of flagella. Internal photosynthetic membranes were of the lamellar type. Lamellae almost filled the whole cell, forming strands and coils. Photosynthetic pigments were bacteriochlorophyll a and carotenoids of the spirilloxanthin group. The new bacterium was strictly anaerobic. Under anoxic conditions, hydrogen sulfide and elemental sulfur were used as photosynthetic electron donors. During growth on sulfide, sulfur globules were formed as intermediate oxidation products. They were deposited outside the cytoplasm of the cells, in the peripheral periplasmic space and extracellularly. Thiosulfate was not used. Carbon dioxide, acetate, pyruvate, propionate, succinate, fumarate and malate were utilized as carbon sources. Optimum growth rates were obtained at pH 9.0 and optimum temperature was 30 degrees C. Good growth was observed in a mineral salts medium containing 5 g sodium bicarbonate l-1 without sodium chloride. The new bacterium tolerated up to 60 g sodium chloride l-1 and up to 80 g sodium carbonates l-1. Growth factors were not required. The DNA G + C composition was 56.0-57.4 mol%. Based on physiological, biochemical and genetic characteristics, the newly isolated bacterium is recognized as a new species of a new genus with the proposed name Thiorhodospira sibirica.  (+info)

Bacteriochlorin-protein interactions in native B800-B850, B800 deficient and B800-Bchla(p)-reconstituted complexes from Rhodopseudomonas acidophila, strain 10050. (8/358)

Recently, a method which allows the selective release and removal of the 800 nm absorbing bacteriochlorophyll a (B800) molecules from the LH2 complex of Rhodopseudomonas acidophila strain 10050 has been described [Fraser, N.J. (1999) Ph.D. Thesis, University of Glasgow, UK]. This procedure also allows the reconstitution of empty binding sites with the native pigment Bchla(p), esterified with phytol. We have investigated the bacteriochlorophylla-protein interactions in native, B800 deficient (or B850) and in B8110-bacteriochlorophylla(p)-reconstituted LH2 complexes by resonance Raman spectroscopy. We present the first direct structural evidence which shows that the reconstituted pigments are correctly bound within their binding pockets.  (+info)

Yellow or orange-to-brown pigmented, ovoid or rod-shaped, Gram-negative staining, aerobic strains PE 4-5T and N5-10 m-1 were isolated from brackish water in Lake Peng Co and fresh to brackish water in Lake Namtso on the Tibetan Plateau, China. Bacteriochlorophyll a was produced by the isolates. The predominant cellular fatty acids were C16 : 1, C17 : 1 and C18 : 1 unsaturated fatty acids, C17 : 1ω6c (55.3 %), C17 : 1ω8c (13.0 %) and C18 : 1ω7c (10.4 %) for PE 4-5T and C18 : 1ω7c (54.7 %) and C16 : 1ω7c (18.0 %) for N5-10 m-1. The polar lipid profiles of strains PE 4-5T and N5-10 m-1 were composed of diphosphatidylglycerol, phosphatidylcholine (not detected in N5-10 m-1), phosphatidyldimethylethanolamine, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylglycerol, sphingoglycolipid and an unknown phospholipid. The predominant respiratory quinone was ubiquinone Q10 and the DNA G+C content was 66.0 mol% for both strains. The16S rRNA gene sequence of strain PE 4-5T shared 99.0 %

Bacterial antenna complex proteins are the main light-absorbing components in photosynthetic bacteria. Also known as a light-harvesting complex/system, the bacterial antenna complex is responsible for the transfer of solar energy to the photosynthetic reaction centre. The bacterial antenna complexes of all photosynthetic bacteria have similar features. They consist of light-absorbing pigments that are either non-covalently associated with integral proteins in the case of purple photosynthetic bacteria and cyanobacteria, or present in chlorosomes in the case of green photosynthetic bacteria. The light-absorbing pigments in chlorosomes do not associate with integral proteins for assembly. Green and purple photosynthetic bacteria utilize different bacteriochlorophyll molecules while cyanobacteria contain chlorophyll, the light-absorbing pigments found in plants. Purple photosynthetic bacteria, particularly Rhodopseudomonos acidophilia of purple non-sulfur bacteria, have been one of the main groups ...
Bacteriochlorophylls are photosynthetic pigments that occur in various phototrophic bacteria. They were discovered by C. B. van Niel in 1932. They are related to chlorophylls, which are the primary pigments in plants, algae, and cyanobacteria. Groups that contain bacteriochlorophyll conduct photosynthesis, but do not produce oxygen. They use wavelengths of light not absorbed by plants or Cyanobacteria. Different groups contain different types of bacteriochlorophyll: ...
Enhancement of the nonresonant second order molecular hyperpolarizabilities {gamma} were observed in stacked macrocyclic molecular systems, previously in a {micro}-oxo silicon phthalocyanine (SiPcO) monomer, dimer and trimer series, and now in bacteriochlorophyll a (BChla) arrays of light harvesting (LH) proteins. Compared to monomeric BChla in a tetrahydrofuran (THF) solution, the |{gamma}| for each macrocycle was enhanced in naturally occurring stacked macrocyclic molecular systems in the bacterial photosynthetic LH proteins where BChla`s are arranged in tilted face-to-face arrays. In addition, the {gamma} enhancement is more significant in B875 of LH1 than in B850 in LH2. Theoretical modeling of the nonresonant {gamma} enhancement using simplified molecular orbitals for model SiPcO indicated that the energy level of the two photon state is crucial to the {gamma} enhancement when a two photon process is involved, whereas the charge transfer between the monomers is largely responsible when one photon

The synthesis of bacteriochlorophyll (Bchl) was inhibited in wild type strain of Rhodopseudomonas capsulata by levulinic acid (LA), δ-aminolevulinic acid of α,α′-dipyridyl. The transcription of genes for pigment-binding proteins, the synthesis and incorporation of these proteins into the membrane and the assembly of photosynthetic complexes were studied. Inhibition of Bchl synthesis did not impair formation of mRNA for pigment-binding polypeptides, but inhibited the synthesis of these proteins as well as stable incorporation into the membrane. The results let suggest, that Bchl is necessary for the stabilization of pigment-binding proteins in the membrane, and that intermediates of Bchl-synthesis affect the synthesis of these proteins. The same experiments were carried out with mutant strains blocked in Bchl synthesis. All Bchl-less mutant strains investigated here, showed transcription of photosynthetic genes at a rate which was independent of oxygen tension. The synthesis of polypeptides of

The evolutionary origin of photosynthetic reaction centers has long remained elusive. Here, we use sequence and structural analysis to demonstrate an evolutionary link between the cytochrome b subunit of the cytochrome bc(1) complex and the core polypeptides of the photosynthetic bacterial reaction center. In particular, we have identified an area of significant sequence similarity between a three contiguous membrane-spanning domain of cytochrome b, which contains binding sites for two hemes, and a three contiguous membrane-spanning domain in the photosynthetic reaction center core subunits, which contains binding sites for cofactors such as (bacterio)chlorophylls, (bacterio)pheophytin and a non-heme iron. Three of the four heme ligands in cytochrome b are found to be conserved with the cofactor ligands in the reaction center polypeptides. Since cytochrome b and reaction center polypeptides both bind tetrapyrroles and quinones for electron transfer, the observed sequence, functional and ...

The delta psi of R. sphaeroides, grown under high light to reduce the levels of light-harvesting bacteriochlorophyll, was naturally manipulated using light intensity. The relationship between delta psi and the swimming speed of free swimming populations of cells was investigated. After de-energisation by incubation in the dark there was an apparent threshold of about -13 mV which had to be overcome before functional motor rotation could resume and at -45 mV the motor saturated. Further increases in delta psi over -45 mV did not increase the free swimming velocity. However, when a chemokinetic effector was added there was an increase in swimming speed, even though the delta psi was well above saturation, indicating that the chemokinetic response is independent of normal relationship between motor rotation and delta psi.
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 ...

In Phase I, GeneXpress Informatics (GXI) and Dr. James P. Chambers of the University of Texas at San Antonio proposed to develop biological obscurants for battlefield applications based on the use of bacteriochlorophylls. Upon completion and presentation of results to MARCORSYSCOM, GXI and Chambers provided the necessary technical proof-of-concept for the Phase II deployment of a biological based obscurant. In Phase II, GXI and Dr. Chambers proposes to fabricate a biological obscurant prototype. The main goal of the Phase II program will be the development of biological molecules which have spectroscopic characteristics for optimal obscuration at wavelengths of interest to the MARCORSYSCOM and the DoD. Spectral absorption tuning of the chlorophyll compounds will be accomplished using site-directed mutagenesis of chlorophyll a oxygenase and genetic constructs developed in the Phase I. The emphasis will be placed on bacteria mutant strains and examination of pilot bioreactor processing. The ideal ...

Chloroflexus aurantiacus is a photosynthetic bacterium isolated from hot springs, belonging to the green non-sulfur bacteria. This organism is thermophilic and can grow at temperatures from 35 °C to 70 °C. Chloroflexus aurantiacus can survive in the dark if oxygen is available. When grown in the dark, Chloroflexus aurantiacus has a dark orange color. When grown in sunlight it is dark green. The individual bacteria tend to form filamentous colonies enclosed in sheaths, which are known as trichomes. As a genus, Chloroflexus spp. are filamentous anoxygenic phototrophic (FAP) organisms that utilize type II photosynthetic reaction centers containing bacteriochlorophyll a similar to the purple bacteria, and light-harvesting chlorosomes containing bacteriochlorophyll c similar to green sulfur bacteria of the Chlorobi. Like other members of its phylum (cf. Chloroflexi), the species stains Gram negative, yet has a single lipid layer (monoderm), but with thin peptidoglycan, which is compensated for by ...
Summary: Four strains of the thermophilic phototrophic green bacterium Chloroflexus aurantiacus were tested for nitrogenase activity under a variety of nutritional conditions consistent with nitrogenase derepression in anoxygenic photosynthetic bacteria. Although all strains of C. aurantiacus could grow with various amino acids as sole nitrogen sources, no growth on N2 was observed; acetylene reduction was undetectable in cells grown under any nutritional conditions. The inability of Chloroflexus to fix N2 is discussed in connection with its thermophilic character.
Green photosynthetic bacteria adjust the structure and functionality of the chlorosome - the light absorbing antenna complex - in response to environmental stress factors. The chlorosome is a natural self-assembled aggregate of bacteriochlorophyll (BChl) molecules. In this study we report the regulation of the biogenesis of the Chlorobaculum tepidum chlorosome by carbon assimilation in conjunction with temperature changes. Our studies indicate that the carbon source and thermal stress culture of Cba. tepidum grows slower and incorporates less BChl c in the chlorosome. Compared with the chlorosome from other cultural conditions we investigated, the chlorosome from the carbon source and thermal stress culture displays: (a) smaller cross-sectional radius and overall size; (b) simplified BChl c homologues with smaller side chains; (c) blue-shifted Qy absorption maxima and (d) a sigmoid-shaped circular dichroism (CD) spectra. Using a theoretical model we analyze how the observed spectral ...

The green sulfur bacteria are a family of obligately anaerobic photoautotrophic bacteria. Most closely related to the distant Bacteroidetes, they are accordingly assigned their own phylum.[1] Green sulfur bacteria are nonmotile (except Chloroherpeton thalassium, which may glide)[1] and occur in spheres, rods, and spirals.[citation needed] Photosynthesis is achieved using a Type 2[citation needed] Reaction Centre using bacteriochlorophyll (BChl) a and in chlorosomes which employ BChl c, d, or e; in addition chlorophyll a is also present,.[1] They use sulfide ions, hydrogen or ferrous iron as an electron donor and the process is mediated by the type I reaction centre and Fenna-Matthews-Olson complex. Elemental sulfur deposited outside the cell may be further oxidized. By contrast, the photosynthesis in plants uses water as the electron donor and produces oxygen.[1] Chlorobium tepidum has emerged as a model organism for the group; although only 10 genomes have been sequenced, these are quite ...
TY - JOUR. T1 - On the Mechanism of Light Harvesting in Photosynthetic Purple Bacteria. T2 - B800 to B850 Energy Transfer. AU - Scholes, Gregory D.. AU - Fleming, Graham R.. PY - 2000/3/2. Y1 - 2000/3/2. N2 - The rate of energy transfer from B800 to B850 in the peripheral light harvesting complex LH2 is modeled in detail. A method for determining ensemble average energy transfer rates in complex, coupled multichromophoric systems is reported and is employed to investigate the interplay of electron-phonon coupling (fast fluctuations of the protein) and site energy disorder (slow fluctuations) on the spectral overlap between donor and acceptor, and therefore the energy transfer rate. A series of model calculations for Rb. sphaeroides is reported. The disorder is found to have a marked influence on the calculated rate of energy transfer and is responsible for a faster energy transfer time than would occur in its absence and furthermore accounts for the weak temperature dependence observed in ...

Catalyzes the formation of the isocyclic ring in chlorophyll biosynthesis. Mediates the cyclase reaction, which results in the formation of divinylprotochlorophyllide (Pchlide) characteristic of all chlorophylls from magnesium-protoporphyrin IX 13-monomethyl ester (MgPMME).
Photophosphorylation in vivo by Chlorobium limicola was inhibited by lipophilic cations and the energy-transfer inhibitors diphenylphosphorylazide, Dio-9, 4-chloro-7-nitrobenzofurazan and chlorhexidene. Membrane-bound ATPase activity was also inhibited by these energy-transfer inhibitors. The formation of a membrane potential was stimulated approximately 1.7-fold on illumination, rising to a value between −110 and −150 mV. The sensitivity of the processes producing this membrane potential to uncouplers, energy-transfer inhibitors and 2-heptyl-4-hydroxyquinoline-N-oxide was measured in the light and the dark.

N2 - Markedly different light-induced protonational changes were measured in two reaction center mutants of Rhodobacter sphaeroides. A quadruple mutant containing alterations, at residues L131, M160, M197, and M210, that elevate the midpoint potential of the bacteriochlorophyll dimer was compared to the YM mutant, which contains these alterations plus a tyrosine at M164 serving as a secondary electron donor [Kálmán et al., Nature 402 (1999) 696]. In the quadruple mutant, a proton uptake of 0.1-0.3 H+/reaction center between pH 6 and 10 resulted from formation of the oxidized bacteriochlorophyll donor and reduced primary quinone. In the ...

The grown structures were characterized by using various experimental techniques, showing a high crystalline quality and very precise growth control. The lifetime of the LH1 excited state was determined directly with pump-probe spectroscopy. The measurements indicated an increase of the lifetime by a factor of ~2 due to ...
Polyethylene glycol (PEG) is a unique polymer material with enormous applicability in many industrial and scientific fields. Here, its use as macromolecular crowder to mimic the cellular environment in vitro is the focus of the present study. We show that femtosecond mid-IR pump-probe spectroscopy using three different IR probes, HDO, HN3, and azido-derivatized crowder, provides complete and stereoscopic information on water structure and dynamics in the cytoplasm-like macromolecular crowding environment. Our experimental results suggest two distinct subpopulations of water molecules: those that interact with other water molecules and those that are part of a hydration shell of crowder on its surface. Interestingly, water dynamics even in highly crowded environment remains bulk-like in spite of significant perturbation to the tetrahedral H-bonding network of water molecules. That is possible because of the formation of water aggregates (pools) even in water-deficient PEGDME-water solutions. In ...

Phototrophs use bacteriochlorophyll pigments in the plasma membrane to capture photons for photosynthesis. In the second stage of photosynthesis, phototrophs use carbon fixation to produce fuel. This is important for autotrophs and the heterotrophs that eat them. It also plays a role in evolution.
