the sulfate-reducing bacterium desulfovibrio desulfuricans nd132 as a model for understanding bacterial mercury methylation.we propose the use of desulfovibrio desulfuricans nd132 as a model species for understanding the mechanism of microbial hg methylation. strain nd132 is an anaerobic dissimilatory sulfate-reducing bacterium (dsrb), isolated from estuarine mid-chesapeake bay sediments. it was chosen for study because of its exceptionally high rates of hg methylation in culture and its metabolic similarity to the lost strain d. desulfuricans ls, the only organism for which methylation pathways have been partially d ...201121515733
active transport, substrate specificity, and methylation of hg(ii) in anaerobic bacteria.the formation of methylmercury (mehg), which is biomagnified in aquatic food chains and poses a risk to human health, is effected by some iron- and sulfate-reducing bacteria (ferb and srb) in anaerobic environments. however, very little is known regarding the mechanism of uptake of inorganic hg by these organisms, in part because of the inherent difficulty in measuring the intracellular hg concentration. by using the ferb geobacter sulfurreducens and the srb desulfovibrio desulfuricans nd132 as ...201121555571
[regulation of sulfates, hydrogen sulfide and heavy metals level in technogenic reservoirs by sulfate-reducing bacteria].sulfate-reducing bacteria desulfovibrio desulfuricans ya-11 in the presence of sulfates and organic compounds in the medium reduce sulfates to hydrogen sulfide (dissimilatory sulfate reduction). heavy metals in concentration over 2 mm inhibit this process. pb2+, zn2+, ni2+, co2+, fe2+ and cd2+ ions in concentration 1-1.5 mm display insignificant inhibiting effect on sulfate reduction process, and metals precipitate in the form of sulfides. at concentrations of heavy metals 2-3 mm one can observe ...201121598657
bacterial growth phase influences methylmercury production by the sulfate-reducing bacterium desulfovibrio desulfuricans nd132.the effect of bacterial growth phase is an aspect of mercury (hg) methylation that previous studies have not investigated in detail. here we consider the effect of growth phase (mid-log, late-log and late stationary phase) on hg methylation by the known methylator desulfovibrio desulfuricans nd132. we tested the addition of hg alone (chloride-complex), hg with suwannee river natural organic matter (srnom) (unequilibrated), and hg equilibrated with srnom on monomethylmercury (mmhg) production by ...201121762955
abundance and diversity of mucosa-associated hydrogenotrophic microbes in the healthy human colon.hydrogenotrophic microbiota have a significant impact on colonic health; however, little is known about their diversity and ecology in situ. here, molecular-based methods and multivariate analyses were used to examine the abundance and diversity of mucosa-associated hydrogenotrophic microbes in 90 biopsies collected from right colon, left colon and rectum of 25 healthy subjects. functional genes of all three hydrogenotrophic groups were detected in at least one colonic region of all subjects. me ...201121753800
combating bacterial colonization on metals via polymer coatings: relevance to marine and medical applications.metals are widely used in engineering as well as medical applications. however, their surfaces are easily colonized by bacteria that form biofilms. among the numerous concerns with biofilm formation, biocorrosion is of particular importance in industry, because structural integrity may be compromised, leading to technical failures. in the food industry and medical field, biofilms also pose health risks. to inhibit bacterial colonization, the surfaces of metals can be coated with a polymeric laye ...201121732600
[a case of desulfovibrio desulfuricans cultured from blood in japan].we report a case of desulfovibrio desulfuricans bacteremia in a 60-year-old-man. in our case, anaerobic blood culture bottle turned out positive after five days' incubation. gram stain showed the presence of slightly-curved gram negative rod. suspecting campylobacter and helicobacter, we added microaerobic culture while tentatively reporting campylobacter to the physician. we then added anaerobic culturing with brucella hk (rs) agar because microaerobic culture proved the absence of microaerophi ...201121706860
complete genome sequence and updated annotation of desulfovibrio alaskensis g20.desulfovibrio alaskensis g20 (formerly desulfovibrio desulfuricans g20) is a gram-negative mesophilic sulfate-reducing bacterium (srb), known to corrode ferrous metals and to reduce toxic radionuclides and metals such as uranium and chromium to sparingly soluble and less toxic forms. we present the 3.7-mb genome sequence to provide insights into its physiology.201121685289
The importance of the protein framework for the catalytic activity of [FeFe]-hydrogenases.The active center (H-cluster) of [FeFe]-hydrogenases is embedded into a hydrophobic pocket within the protein. We have analyzed several amino acids, located in the vicinity of this niche, by site-directed mutagenesis of the [FeFe]-hydrogenases from Clostridium pasteurianum (CpI) and Chlamydomonas reinhardtii (CrHydA1). These amino acids are highly conserved and predicted to be involved in H-cluster coordination. Characterization of two hydrogenase variants confirmed this hypo-thesis. The exchang ...201122110126
Desulfovibrio desulfuricans Bacteremia in an Immunocompromised Host with a Liver Graft and Ulcerative Colitis.Desulfovibrio spp. are anaerobic, sulfate-reducing, nonfermenting, Gram-negative bacteria found in the digestive tract of humans. Identification of these species with conventional methods is difficult. The reported case of a Desulfovibrio desulfuricans bacteremia occurring in an immunocompromised host with ulcerative colitis confirms that this organism may be a possible opportunistic human pathogen.201222075582
mechanistic and physiological implications of the interplay among iron-sulfur clusters in [fefe]-hydrogenases. a qm/mm perspective.key stereoelectronic properties of desulfovibrio desulfuricans [fefe]-hydrogenase (ddh) were investigated by quantum mechanical description of its complete inorganic core, which includes a fe(6)s(6) active site (the h-cluster), as well as two ancillary fe(4)s(4) assemblies (the f and f' clusters). the partially oxidized, active-ready form of ddh is able to efficiently bind dihydrogen, thus starting h(2) oxidation catalysis. the calculations allow us to unambiguously assign a mixed fe(ii)fe(i) st ...201121942468
glutathione level of desulfovibrio desulfuricans imv k-6 under the influence of heavy metal salts.glutathione is the metal stress protector and changes of its level in the sulfate-reducing bacteria cells under the influence of heavy metal salts have not been studied yet. cdcl2, pb(no3)2, cucl2, and zncl2 influence on the total glutathione level in cell-free extracts of sulfate-reducing bacteria desulfovibrio desulfuricans imv k-6 was studied. the research has been carried out using ellman, lowry methods, statistical processing of the results. it was shown that the glutathione level depends o ...201122364026
computed tomographic evaluation of the breast.experience with a dedicated breast ct scanner (general electric ct/m) using a contrast medium enhancement technique indicates that ct is superior to mammography, thermography, or physical examination for diagnosing both benign and malignant mammary disease especially in dense, thick, or fibrocystic breasts. ct is capable of diagnosing totally unsuspected early miniature carcinomas. it can identify and differentiate potential precancerous lesions from benign fibrocystic disease, and is the diagno ...200098990
cerebral perfusion pressure: a hemodynamic mechanism of mannitol and the postmannitol hemogram.sixteen patients each received infusions of 1 g of mannitol per kg over 5 to 10 minutes, and serial determinations of intracranial pressure (icp), systemic arterial blood pressure (sabp), central venous pressure, cerebral perfusion pressure (cpp), hematocrit, hemoglobin, serum na+, k+, osmolarity, and fluid balance were carried out for 4 hours. urine output was replaced volume for volume with 5% dextrose in 0.45% nacl solution. we tested the hypothesis that patients with high (greater than or eq ...20103116451
