Flagellate predation on a bacterial model community: interplay of size-selective grazing, specific bacterial cell size, and bacterial community composition. (1/52)

The influence of grazing by the bacterivorous nanoflagellate Ochromonas sp. strain DS on the taxonomic and morphological structures of a complex bacterial community was studied in one-stage chemostat experiments. A bacterial community, consisting of at least 30 different strains, was fed with a complex carbon source under conditions of low growth rate (0.5 day(-1) when nongrazed) and low substrate concentration (9 mg liter(-1)). Before and after the introduction of the predator, the bacterial community composition was studied by in situ techniques (immunofluorescence microscopy and fluorescent in situ hybridization), as well as by cultivation on agar media. The cell sizes of nonspecifically stained and immunofluorescently labeled bacteria were measured by image analysis. Grazing by the flagellate caused a bidirectional change in the morphological structure of the community. Medium-size bacterial cells, which dominated the nongrazed community, were largely replaced by smaller cells, as well as by cells contained in large multicellular flocs. Cell morphological changes were combined with community taxonomic changes. After introduction of the flagellate, the dominating strains with medium-size cells were largely replaced by single-celled strains with smaller cells on the one hand and, on the other hand, by Pseudomonas sp. strain MWH1, which formed the large, floc-like forms. We assume that size-selective grazing was the major force controlling both the morphological and the taxonomic structures of the model community.  (+info)

Development of a vital fluorescent staining method for monitoring bacterial transport in subsurface environments. (2/52)

Previous bacterial transport studies have utilized fluorophores which have been shown to adversely affect the physiology of stained cells. This research was undertaken to identify alternative fluorescent stains that do not adversely affect the transport or viability of bacteria. Initial work was performed with a groundwater isolate, Comamonas sp. strain DA001. Potential compounds were first screened to determine staining efficiencies and adverse side effects. 5-(And 6-)-carboxyfluorescein diacetate, succinimidyl ester (CFDA/SE) efficiently stained DA001 without causing undesirable effects on cell adhesion or viability. Members of many other gram-negative and gram-positive bacterial genera were also effectively stained with CFDA/SE. More than 95% of CFDA/SE-stained Comamonas sp. strain DA001 cells incubated in artificial groundwater (under no-growth conditions) remained fluorescent for at least 28 days as determined by epifluorescent microscopy and flow cytometry. No differences in the survival and culturability of CFDA/SE-stained and unstained DA001 cells in groundwater or saturated sediment microcosms were detected. The bright, yellow-green cells were readily distinguished from autofluorescing sediment particles by epifluorescence microscopy. A high throughput method using microplate spectrofluorometry was developed, which had a detection limit of mid-10(5) CFDA-stained cells/ml; the detection limit for flow cytometry was on the order of 1,000 cells/ml. The results of laboratory-scale bacterial transport experiments performed with intact sediment cores and nondividing DA001 cells revealed good agreement between the aqueous cell concentrations determined by the microplate assay and those determined by other enumeration methods. This research indicates that CFDA/SE is very efficient for labeling cells for bacterial transport experiments and that it may be useful for other microbial ecology research as well.  (+info)

Monitoring bacterial transport by stable isotope enrichment of cells. (3/52)

Understanding the transport and behavior of bacteria in the environment has broad implications in diverse areas, ranging from agriculture to groundwater quality, risk assessment, and bioremediation. The ability to reliably track and enumerate specific bacterial populations in the context of native communities and environments is key to developing this understanding. We report a novel bacterial tracking approach, based on altering the stable carbon isotope value (delta(13)C) of bacterial cells, which provides specific and sensitive detection and quantification of those cells in environmental samples. This approach was applied to the study of bacterial transport in saturated porous media. The transport of introduced organisms was indicated by mass spectrometric analysis of groundwater samples, where the presence of (13)C-enriched bacteria resulted in increased delta(13)C values of the samples, allowing specific and sensitive detection and enumeration of the bacteria of interest. We demonstrate the ability to produce highly (13)C-enriched bacteria, present data indicating that results obtained with this approach accurately represent intact introduced bacteria, and include field data on the use of this stable isotope approach to monitor in situ bacterial transport. This detection strategy allows sensitive detection of an introduced, unmodified bacterial strain in the presence of the indigenous bacterial community, including itself in its unenriched form.  (+info)

Different mechanisms of the binding of soluble electron donors to the photosynthetic reaction center of Rubrivivax gelatinosus and Blastochloris viridis. (4/52)

The tetraheme cytochrome subunits of the photosynthetic reaction centers (RCs) in two species of purple bacteria, Rubrivivax gelatinosus and Blastochloris (Rhodopseudomonas) viridis, were compared in terms of their capabilities to bind different electron-donor proteins. The wild-type RCs from both species and mutated forms of R. gelatinosus RCs (with amino acid substitutions introduced to the binding domain for electron-donor proteins) were tested for their reactivity with soluble cytochromes and high potential iron-sulfur protein. Cytochromes from both species were good electron donors to the B. viridis RC and the R. gelatinosus RC. The reactivity in the R. gelatinosus RC showed a clear dependence on the polarity of the charges introduced to the binding domain, indicating the importance of the electrostatic interactions. In contrast, high potential iron-sulfur protein, presumed to operate according to the hydrophobic mechanism of binding, reacted significantly only with the R. gelatinosus RC. Evolutionary substitution of amino acids in a region of the binding domain on the cytochrome subunit surface probably caused the change in the principal mode of protein-protein interactions in the electron-transfer chains.  (+info)

Comamonas nitrativorans sp. nov., a novel denitrifier isolated from a denitrifying reactor treating landfill leachate. (5/52)

A group of Gram-negative denitrifying bacteria has been isolated from a denitrifying reactor treating landfill leachate. The new isolates produced both oxidase and catalase and showed growth on acetate, butyrate, n-caproate, i-butyrate, i-valerate, propionate, n-valerate, lactate, alanine, benzoate, phenylalanine and ethanol. No growth was observed on sugars. The bacteria could perform anoxic reduction of nitrate, nitrite and nitrous oxide to nitrogen, coupled to the oxidation of the same substrates as those used under aerobic conditions, except for aromatic compounds. They were very efficient denitrifiers, as estimated from the specific rate of N2 gas production. All the strains showed the same 16S rDNA restriction profile and one of them, designated 23310T, was selected for phylogenetic analysis. The organism clustered within the family Comamonadaceae, being related to Comamonas terrigena (95.8% sequence similarity). On the basis of the phylogenetic analysis, physiological characterization and the ability to efficiently reduce nitrate to N2, it is proposed that the bacterium be assigned to a new species, Comamonas nitrativorans. The type strain is 23310T (= DSM 13191T = NCCB 100007T = CCT 7062T).  (+info)

Comamonas denitrificans sp. nov., an efficient denitrifying bacterium isolated from activated sludge. (6/52)

To find a biomarker for denitrification in activated sludge, five denitrifying strains isolated from three wastewater treatment plants were studied. These strains were selected from among 1,500 isolates for their excellent denitrifying properties. They denitrify quickly and have no lag phase when switching from aerobic to anoxic conditions. All strains have the cd1-type of nitrite reductase. The strains are Gram-negative rods and they all grow as filamentous chains when cultivated in liquid solution. The strains differ in colony morphology when grown on nutrient agar. Almost full-length 16S rDNA sequences were determined and phylogenetic analysis revealed that these strains are positioned among members of the genus Comamonas in the beta-subclass of the Proteobacteria. Signature nucleotides and bootstrap percentages were also analysed to verify this position. Strains 110, 123T, 2.99g, 5.38g and P17 were < or = 96.7% similar to known strains, but > or = 99.7% similar to each other, as judged from their 16S rDNA sequences, and grouped tightly together in the phylogenetic tree. Sequence motifs in the 16S rRNA gene were also found, suggesting the monophyletic origin of these strains. Nevertheless, some strains differed from the others, for example strain 110 branches early from the other strains and 5.38g is phenotypically more inert. Therefore, it is proposed that strains 110, 123T, 2.99g and P17 are classified into a new species, Comamonas denitrificans sp. nov., while the taxonomic status of strain 5.38g will have to await the outcome of further studies. The type strain of Comamonas denitrificans is 123T (ATCC 700936T).  (+info)

Evidence for detachment of indigenous bacteria from aquifer sediment in response to arrival of injected bacteria. (7/52)

Two bacterial strains isolated from the aquifer underlying Oyster, Va., were recently injected into the aquifer and monitored using ferrographic capture, a high-resolution immunomagnetic technique. Injected cells were enumerated on the basis of a vital fluorescence stain, whereas total cell numbers (stained target cells plus unstained target and antigenically similar indigenous bacteria) were identified by cell outlines emanating from fluorophore-conjugated antibodies to the two target strains. The arrival of injected bacteria at the majority of monitored sampling ports was accompanied by simultaneous temporary increases in unstained cell counts that outnumbered the injected bacteria by 2- to 100-fold. The origin and mechanism of appearance of the unstained cells are considered.  (+info)

Crystal structure of quinohemoprotein alcohol dehydrogenase from Comamonas testosteroni: structural basis for substrate oxidation and electron transfer. (8/52)

Quinoprotein alcohol dehydrogenases are redox enzymes that participate in distinctive catabolic pathways that enable bacteria to grow on various alcohols as the sole source of carbon and energy. The x-ray structure of the quinohemoprotein alcohol dehydrogenase from Comamonas testosteroni has been determined at 1.44 A resolution. It comprises two domains. The N-terminal domain has a beta-propeller fold and binds one pyrroloquinoline quinone cofactor and one calcium ion in the active site. A tetrahydrofuran-2-carboxylic acid molecule is present in the substrate-binding cleft. The position of this oxidation product provides valuable information on the amino acid residues involved in the reaction mechanism and their function. The C-terminal domain is an alpha-helical type I cytochrome c with His(608) and Met(647) as heme-iron ligands. This is the first reported structure of an electron transfer system between a quinoprotein alcohol dehydrogenase and cytochrome c. The shortest distance between pyrroloquinoline quinone and heme c is 12.9 A, one of the longest physiological edge-to-edge distances yet determined between two redox centers. A highly unusual disulfide bond between two adjacent cysteines bridges the redox centers. It appears essential for electron transfer. A water channel delineates a possible pathway for proton transfer from the active site to the solvent.  (+info)

A bacterial strain, designated YH12T, was isolated from a wetland sample collected from Woopo, Republic of Korea, and characterized using a polyphasic approach. Analysis of 16S rDNA indicated that the isolate formed a monophyletic clade with the members of the genus Comamonas. The closest phylogenetic relative among the valid species was Comamonas testosteroni, with 96.6% 16S rDNA similarity. The chemotaxonomic properties of the wetland isolate supported its membership of the genus Comamonas, as it contained ubiquinone Q-8 as a major respiratory quinone and hexadecanoic, methylene-hexadecanoic and octadecenoic acids as major cellular fatty acids. The G+C content of the DNA was 66 mol%. The isolate is a gram-negative, non-pigmented, rod-shaped, oxidase- and catalase-positive, non-motile, non-endospore-forming and non-fermentative bacterium. The phenotypic properties of the isolate were compared with those of the type strains of Comamonas terrigena, C. testosteroni and Delftia acidovorans. A number of

2-Chloronitrobenzene and 4-chloronitrobenzene are oily yellow solids that are used primarily as chemical intermediates in the production of dyes, lumber preservatives, drugs, and photographic chemicals. Although these chemicals are solids at room temperature, the vapor pressures of these chemicals are sufficiently high to result in significant inhalation exposure. Toxicity studies of 2-chloronitrobenzene and 4-chloronitrobenzene were performed by exposing male and female F344/N rats and B6C3F1 mice to the chemicals by whole-body inhalation 6 hours per day, 5 days per week, for 2 weeks or 13 weeks. Animals were evaluated for histopathology, clinical chemistry (rats), hematology (rats), and reproductive system effects. In separate studies, the dermal absorption ofthe chemicals was compared, and the absorption, distribution, metabolism, and excretion were partially characterized following oral administration to male F344/N rats. 2-Chloronitrobenzene and 4-chloronitrobenzene were also administered ...
Abstract : The chloronitrobenzenes are widely used as the intermediates in the production of pharmaceuticals, pesticidesand rubber processing chemicals. However, due to their wide applications, they are frequently released into theenvironment thereby creating hazards. The objective of the study was to use an alternative strategy i.e. biofieldenergy treatment and analysed its impact on the physical, thermal and spectral properties of 3-chloronitrobenzene(3-CNB). For the study, the 3-CNB sample was taken and divided into two groups, named as control and treated.The analytical techniques used were X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential scanningcalorimetry (DSC), UV-Visible (UV-Vis), and Fourier transform infrared (FT-IR) spectroscopy. The treated groupwas subjected to the biofield energy treatment and analysed using these techniques against the control sample.The XRD data showed an alteration in relative intensity of the peak along with 30% decrease in the ...
Dietary composition has major effects on physiology. Here, we show that developmental rate, reproduction, and lifespan are altered in C. elegans fed Comamonas DA1877 relative to those fed a standard E. coli OP50 diet. We identify a set of genes that change in expression in response to this diet and use the promoter of one of these (acdh-1) as a dietary sensor. Remarkably, the effects on transcription and development occur even when Comamonas DA1877 is diluted with another diet, suggesting that Comamonas DA1877 generates a signal that is sensed by the nematode. Surprisingly, the developmental effect is independent from TOR and insulin signaling. Rather, Comamonas DA1877 affects cyclic gene expression during molting, likely through the nuclear hormone receptor NHR-23. Altogether, our findings indicate that different bacteria elicit various responses via distinct mechanisms, which has implications for diseases such as obesity and the interactions between the human microbiome and intestinal ...

Hospital-acquired infections due to Acinetobacter baumannii have become problematic because of high rates of drug resistance. A. baumannii is usually harmless, but it causes sepsis resulting in a high mortality rate in compromised hosts. Therefore, we must consider its interaction with host cells to understand diseases resulting from A. baumannii infection. Neutrophils play a critical role in infective protection against the extracellular growth of bacteria. However, their interactions with A. baumannii remain largely unknown. Recently, a new biological defense mechanism called neutrophil extracellular traps (NETs) has been attracting attention. In the present study, we investigated the responsiveness of human neutrophils to A. baumannii focusing on NET formation. The results demonstrated that infective protection against Pseudomonas aeruginosa via NETs formation was observed, but for A. baumannii NETs formation did not occur. It seems that the innate infective protection against A. baumannii ...
The metabolism of radiolabeled monochloronitrobenzene isomers was compared in isolated hepatocytes and hepatic subcellular fractions from male Fischer-344 rats. 2-Chloronitrobenezene was converted by isolated hepatocytes to 2-chloroaniline, 2-chloroaniline-N-glucuronide, and S-(2-nitrophenyl)glutathione in approximately equal quantities (13-19% of the added substrate in 90 min). The major metabolite formed from 3-chloronitrobenzene by isolated hepatocytes was 3-chloroaniline (31% of the added substrate in 90 min). Smaller amounts of 3-chloroaniline-N-glucuronide and 3-chloroacetanilide were formed (7 and 17% of the added 3-chloronitrobenzene, respectively, in 90 min). 4-Chloronitrobenzene was metabolized to 4-chloroacetanilide, 4-chloroaniline, and S-(4-nitrophenyl)glutathione in approximately equal amounts (10-15% of the added substrate in 90 min). Studies with hepatic microsomes showed that reduction of the chloronitrobenzenes to chloroanilines was inhibited by SKF 525-A, metyrapone, and ...

Glycolysis is the process of converting glucose into pyruvate and generating small amounts of ATP (energy) and NADH (reducing power). It is a central pathway that produces important precursor metabolites: six-carbon compounds of glucose-6P and fructose-6P and three-carbon compounds of glycerone-P, glyceraldehyde-3P, glycerate-3P, phosphoenolpyruvate, and pyruvate [MD:M00001]. Acetyl-CoA, another important precursor metabolite, is produced by oxidative decarboxylation of pyruvate [MD:M00307]. When the enzyme genes of this pathway are examined in completely sequenced genomes, the reaction steps of three-carbon compounds from glycerone-P to pyruvate form a conserved core module [MD:M00002], which is found in almost all organisms and which sometimes contains operon structures in bacterial genomes. Gluconeogenesis is a synthesis pathway of glucose from noncarbohydrate precursors. It is essentially a reversal of glycolysis with minor variations of alternative paths [MD:M00003 ...
Uric acid is the primary end product from purine derivatives in human metabolism. Excessive production of uric acid may lead to gout, hyperuricemia and kidney disorder: Different analytical methods for uric acid such as Colorimetry, commercial enzyme electrode and commercially available uric acid kit are used widely. The main purpose of this research was to develop,a screen printed electrode based uric acid biosensor using gelatin immobilized uricase enzyme extracted from Comamonas sp. BTUA. The enzyme catalyzed oxidation of uric acid in presence of oxygen, producing allantoin and hydrogen peroxide. The linearity of the standard curve in the concentration ranges from 5.94 x 10(-6) to 4.75 x 10(-4) molar was satisfactory and could be used for the quantitative determination of uric acid in human serum samples. The limit of detection (LOD) was 2.26 mu M and sensitivity was evaluated as 3.31 nA mu M-1 of uric acid. One Modified electrode could be used for six measurements with 95%. accuracy up to 25 ...

Correlations between microbial transport and runoff characteristics were identified. Results indicate that diet affects phage but not bacterial transport from manure-amended fields.
The phosphoenolpyruvate (PEP)-dependent phosphotransferase system (PTS) is a major mechanism used by bacteria for uptake of carbohydrates, particularly hexoses, hexitols, and disaccharides, where the source of energy is from PEP. The PTS consists of two general components, enzyme I (EI) and histidine phosphocarrier protein (HPr), and of membrane-bound sugar specific permeases (enzymes II). Each enzyme II (EII) complex consists of one or two hydrophobic integral membrane domains (domains C and D) and two hydrophilic domains (domains A and B). EII complexes may exist as distinct proteins or as a single multidomain protein. The PTS catalyzes the uptake of carbohydrates and their conversion into their respective phosphoesters during transport. There are four successive phosphoryl transfers in the PTS. Initial autophosphorylation of EI, using PEP as a substrate, is followed by transfer of the phosphoryl group from EI to HPr. EIIA catalyzes the self-phosphoryl transfer from HPr after which the ...

In this study, the adsorption of 1-chloro-4-nitrobenzene (1C4NB) on carbon nanofibers (CNFs), was investigated in a batch system. The combined effects of operating parameters such as contact time, pH, initial 1C4NB concentration, and CNFs dosage on the adsorption of 1C4NB byCNFs were analyzed using response surface methodology (RSM). The analysis of variance results confirmed that there was significant agreement between the model and experimental data. In addition, it was indicated that the residuals followed a normal distribution.The screening experiments showed that significant factors in 1C4NB removal were CNFs dosage, interaction between initial 1C4NB concentration-CNFs dosage and CNFs dosage-contact time. High efficiency removal (|90%) was obtained under optimal value of process parameters in the first 6 min of the removal process. The results indicate that RSM is a suitable method for modeling and optimizing the process, so that experimental design by RSM leads to time and cost saving.Non-linear
The Skraup synthesis is a chemical reaction used to synthesize quinolines . It is named after the Czech chemist Zdenko Hans Skraup (1850-1910). In the archetypal Skraup reaction, aniline is heated with sulfuric acid , glycerol , and an oxidizing agent such as nitrobenzene to yield quinoline. In this example, nitrobenzene serves as both the solvent and the oxidizing agent. The reaction, which otherwise has a reputation for being violent, is typically conducted in the presence of ferrous sulfate . Arsenic acid may be used instead of nitrobenzene and the former is better since the reaction is less violent. See also Bischler-Napieralski reaction Doebner-Miller reaction References Skraup, Z. H. (1880).

NITROBENZENE (also called NITROBENZOL ) is a colourless to pale yellow, oily, highly toxic liquid with the odour of bitter almonds. Nitrobenzene is manufactured commercially by nitration of benzene (also a common air pollutant) using a mixture of nitric and sulfuric acids. Commercially nitrobenzene can be either produced in a batch or by a continuous process. Both batch and continuous processes employing mixed nitric and sulfuric acids are used to make nitrobenzene. The continuous process is favored over the batch process because its production capacity is much larger, it has lower capital costs and it entails more efficient labor usage. Reactors for the continuous process also usually utilized lower nitric acid concentrations, are smaller with more rapid and efficient mixing, and therefore have higher reaction rates. Nitrobenzene undergoes nitration, halogenation, and sulfonation much more slowly than does benzene. It may be reduced to a variety of compounds, depending on the reaction ...
C-type lectin (CLEC) receptors are important for initiating and shaping immune responses; however, their role in inflammatory reactions in the central nervous system after traumatic injuries is not known. The antigen-presenting lectin-like receptor gene complex (Aplec) contains a few CLEC genes, which differ genetically among inbred rat strains. It was originally thought to be a region that regulates susceptibility to autoimmune arthritis, autoimmune neuroinflammation and infection. The inbred rat strains DA and PVG differ substantially in degree of spinal cord motor neuron death following ventral root avulsion (VRA), which is a reproducible model of localized nerve root injury. A large F2 (DAxPVG) intercross was bred and genotyped after which global expressional profiling was performed on spinal cords from F2 rats subjected to VRA. A congenic strain, Aplec, created by transferring a small PVG segment containing only seven genes, all C-type lectins, ontoDA background, was used for further experiments

Description: A quantitative test of ENDOR theory for free radicals in solution is performed on the 14N nucleus of the nitrobenzene radical anion in dimethoxyethane. Dominant relaxation contributions are caused by modulation of the electron nuclear dipolar interaction. They can be calculated from the known G and 14N hyperfine tensors of the nitrobenzene radical anion. The effects of spin-rotation interaction and Heisenberg spin exchange at different concentrations are investigated experimentally and theoretically. The concentration and temperature dependences of the 14N ENDOR amplitudes are found to agree well with theoretical predictions. ...

Bacterial strain XII, which belongs to the family Pseudomonad, utilizes 1-chloro-4-nitrobenzene as a sole source of carbon, nitrogen, and energy. Suspensions of 1-chloro-4-nitrobenzene -grown cells removed 1-chloro-4-nitrobenzene from culture fluids, and there was a concomitant release of ammonia and chloride. Under anaerobic conditions XII transformed 1-chloro-4-nitrobenzene into a product which was identified as 2-amino-5-chlorophenol by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry. This transformation indicated that there was partial reduction of the nitro group to the hydroxylamino substituent, followed by Bamberger rearrangement. In the presence of oxygen but in the absence of NAD, fast transformation of 2-amino-5-chlorophenol into a transiently stable yellow product was observed with resting cells and cell extracts. This compound exhibited an absorption maximum at 395 nm and was further converted to a dead-end product with maxima at 226 and 272 nm. The compound

Mutagenetic replacements of conserved residues within the active site of the short-chain dehydrogenase/reductase (SDR) superfamily were studied using prokaryotic 3 beta/17 beta-hydroxysteroid dehydrogenase (3 beta/17 beta-HSD) from Comamonas testosteroni as a model system. The results provide novel data to establish Ser 138 as a member of a catalytically important triad of residues also involving Tyr151 and Lys155. A Ser--|Ala exchange at position 138 results in an almost complete (| 99.9%) loss of enzymatic activity, which is not observed with a Ser--|Thr replacement. This indicates that an essential factor for catalysis is the ability of side chain 138 to form hydrogen bond interactions. Mutations in the NAD(H) binding region, in strands beta A, beta D, and adjacent turns, reveal two additional residues, Thr12 and Asn87, which are important for correct binding of the coenzyme and with a differential effect on the reactions catalyzed. Thus, mutation of Thr12 to Ala results in a complete loss of the 3
Di-2-ethylhexyl terephthalate (DEHTP), a structural isomer of the plasticizer di-2-ethylhexyl phthalate (DEHP), is used in food packaging and medical devices, among other applications, and is a potential replacement for DEHP and other ortho-phthalate plasticizers. Identifying sensitive and specific biomarkers of DEHTP is necessary to assess humans' background exposure to DEHTP. Using mass spectrometry, we investigated the metabolism of DEHTP by human liver microsomes to identify in vitro DEHTP metabolites. We unequivocally identified terephthalic acid (TPA) and mono-2-ethylhydroxyhexyl terephthalate (MEHHTP), using authentic standards, and tentatively identified mono-2-ethylhexyl terephthalate (MEHTP) and two other oxidative metabolites of DEHTP: mono-2-ethyloxohexyl terephthalate (MEOHTP), and mono-2-ethyl-5-carboxypentyl terephthalate (MECPTP) from their mass spectrometry fragmentation patterns. We also evaluated the formation of in vitro metabolites of DEHP. DEHTP and DEHP produced ...

The detection of prohibited performance-enhancing drugs in sports is often carried out using urine samples. The reason for this is that urine samples can be collected under non-sterile conditions and do not require the presence of a sanctioned medical officer. Improper storage of the urine samples from athletes can lead to microbial contamination, which can cause changes in the steroids profile, leading to false positive or false negative results for a particular athlete. To address this problem, a new analytical method was proposed that employs a fluorinated steroid as an internal standard and fluorine-19 nuclear magnetic resonance spectroscopy (19F-NMR) spectroscopy to identify both microbial and thermally-induced changes in the urine samples. In Chapter 2, synthesis of fluorinated steroids was carried out using method that involve the reaction of Selectfluor® with enolates/enols of steroids. A range of fluorinated steroids was prepared (2 novel F-steroids) in moderate yields and varying ...
Research performed at the Division of Environmental Microbiology has over the last years resulted in the isolation of possible bacterial key-organisms with efficient nutrient removal properties (Comamonas denitrificans, Brachymonas denitrificans, Aeromonas hydrophila). Effective use of these organisms for enhanced nutrient removal in wastewater treatment applications requires the strains to be retained, to proliferate and to maintain biological activity within theprocess. This can be achieved by immobilization of the organisms using an appropriate system.Two putative immobilization systems, agar entrapment and biofilm formation, wereassessed. Surface attached biofilm growth provided better results with respect to cell retention,proliferation and microbial activity than immobilization in agar beads. Thus, biofilm physiology was further characterized using simplified systems of single, dual or multi strain bacterial consortia containing the key-organisms as well as other wastewater treatment ...

The distribution and the metabolic pathways of bacteria degrading steroid compounds released by eukaryotic organisms were investigated using the bile salt cholate as model substrate. Cholate-degrading bacteria could be readily isolated from freshwater environments. All isolated strains transiently released steroid degradation intermediates into culture supernatants before their further degradation. Cholate degradation could be initiated via two different reaction sequences. Most strains degraded cholate via a reaction sequence known from the model organism Pseudomonas sp. strain Chol1 releasing intermediates with a 3-keto-Δ,sup,1,4,/sup,-diene structure of the steroid skeleton. The actinobacterium Dietzia sp. strain Chol2 degraded cholate via a different and yet unexplored reaction sequence releasing intermediates with a 3-keto-Δ,sup,4,6,/sup,-diene-7-deoxy structure of the steroid skeleton such as 3,12-dioxo-4,6-choldienoic acid (DOCDA). Using DOCDA as substrate, two Alphaproteobacteria, ...

The thermal shrinkage behaviour of poly(ethylene terephthalate) fibres and films with varying amounts of orientation and crystallinity and different degrees of crystal disorder is reported. It is shown that the shrinkage of undrawn and drawn samples with low orientation can be considered as the contraction of a rubber-like network which arises from disorientation of the oriented amorphous phase. However, in the highly drawn samples with significantly higher orientation, interaction between shrinkage and crystallization can occur, particularly in samples produced at low speeds. X-ray diffraction and thermal studies show that these samples have crystals with high defect density and also contain tiny nuclei; these factors can result in rapid crystallization at relatively high temperatures and thus impede shrinkage.
Hydroxyl group-containing triglyceride oils are effective nucleating agents for poly(ethylene terephthalate) and provide improved crystallization properties. The hydroxyl group-containing triglyceride oil may be combined with a conventional organic acid metal salt nucleating agent. By covalently bonding the hydroxyl group-containing triglyceride oil with a metal carboxylate, improved crystallization properties are obtained.

Results -For the initial runs with the series of 12 ketones (NIOSH #1301), we were able to separate 10 of the components by just increasing the ramp rate from 10o/min to 200 /min. The final time for analysis was 11 minutes. We do have 8 ramp rates and 4 cooling fan rates so with an additional ramp, we should be able to separate methyl amyl ketone and ethyl amyl ketone and use a faster fan rate to reduce the cool down time. For NIOSH Method #1501, we were able to separate 15 of the 17 compounds in 14 minutes instead of 35 minutes. We were not able to separate nitrobenzene and naphthalene but there is a such a significant difference in the PID/FID response ratio that each of the components can be easily identified ...
