Detection of serum proteins in the electrophoretic patterns of total proteins of mycoplasma cells. (1/194)

The contamination of mycoplasma cell preparations by serum proteins originating from culture medium was studied. A. laidlawii and M. arthritidis cells were grown in the presence of [14C]-aminoacids, and the cells were washed with 0-9% NaC1 by threefold centrifugation. Total proteins of the washed cells were analysed by SDS gel electrophoresis. Coomassie-stained electrophoretic patterns were compared with autoradiographs of the same gels. The stained electrophoretic pattern of washed A. laidlawii grown without serum was identical with autoradiographs of the same cells grown without or with serum. That of washed A. laidlawii grown with serum differed from the corresponding autoradiography by the presence of extra protein bands I, II, III, and IV with molecular weights of over 160,000, 80,000-87,000, 55,000 and 25,000, respectively. The same extra bands were found in stained electrophoretic patterns of washed: (a) A. laidlawii cells grown without serum and mixed with serum in the stationary phase, (b) M. arthritidis cells, as compared with their autoradiographs, (c) serum precipitate. The bands III and IV may be due to the heavy and light chains of gamma-globulin, the band II might belong to transferrin or to some component of complement. Acidification of serum to pH 5 brought about 100-fold rise of amount of serum precipitate, the number of bands in the electrophoretic pattern of the precipitate being also increased. Stained electrophoretic patterns of cells purified by twofold centrifugation in step sucrose density gradient (1-20-1-27 g./cm.3 for A. laidlawii, and 1-15-1-25 for M. arthritidis) contained no extra bands and matched completely with their autoradiographs. It was concluded that contamination of washed mycoplasma cells by serum proteins is mainly due to co-precipitation of aggregated serum proteins together with cells during centrifugation rather than to adsorption of serum proteins on the cell surface.  (+info)

Bactericidal/permeability-increasing protein inhibits growth of a strain of Acholeplasma laidlawii and L forms of the gram-positive bacteria Staphylococcus aureus and Streptococcus pyogenes. (2/194)

Bactericidal/permeability-increasing protein (BPI) inhibited growth of cell wall-deficient Acholeplasma laidlawii and L forms of certain strains of Staphylococcus aureus and Streptococcus pyogenes. However, the same strains of S. aureus and S. pyogenes with intact cell walls were not susceptible to the growth-inhibitory effects of BPI.  (+info)

Replication of mycoplasmavirus MVL51: attachment of MVL51 parental DNA to host cell membrane. (3/194)

The replication of the single-stranded circular DNA of MVL51 mycoplasmavirus has been studied with respect to the roles of free and membrane-associated viral DNA intermediates. Replication involves the formation of parental replicative intermediate (RF) molecules on, at most, two to three membrane sites per cell, symmetric RF replication at the membrane and apparent asymmetric RF replication in the cytoplasm leading to single-stranded progeny chromosomes.  (+info)

The nonbilayer/bilayer lipid balance in membranes. Regulatory enzyme in Acholeplasma laidlawii is stimulated by metabolic phosphates, activator phospholipids, and double-stranded DNA. (4/194)

In membranes of Acholeplasma laidlawii a single glucosyltransferase step between the major, nonbilayer-prone monoglucosyl-diacylglycerol (MGlcDAG) and the bilayer-forming diglucosyl-diacylglycerol (DGlcDAG) is important for maintenance of lipid phase equilibria and curvature packing stress. This DGlcDAG synthase is activated in a cooperative fashion by phosphatidylglycerol (PG), but in vivo PG amounts are not enough for efficient DGlcDAG synthesis. In vitro, phospholipids with an sn-glycero-3-phosphate backbone, and no positive head group charge, functioned as activators. Different metabolic, soluble phosphates could supplement PG for activation, depending on type, amount, and valency. Especially efficient were the glycolytic intermediates fructose 1,6-bisphosphate and ATP, active at cellular concentrations on the DGlcDAG but not on the preceding MGlcDAG synthase. Potencies of different phosphatidylinositol (foreign lipid) derivatives differed with numbers and positions of their phosphate moieties. A selective stimulation of the DGlcDAG, but not the MGlcDAG synthase, by minor amounts of double-stranded DNA was additive to the best phospholipid activators. These results support two types of activator sites on the enzyme: (i) lipid-phosphate ones close to the membrane interphase, and (ii) soluble (or particulate)-phosphate ones further out from the surface. Thereby, the nonbilayer (MGlcDAG) to bilayer (DGlcDAG) lipid balance may be integrated with the metabolic status of the cell and potentially also to membrane and cell division.  (+info)

Binding of glycoglycerolipid derived from membranes of Acholeplasma laidlawii PG8 and synthetic analogues to lymphoid cells. (5/194)

A component that binds to human lymphoid cells was isolated from the membranes of Acholeplasma laidlawii PG8. The component was extracted using the Bligh-Dyer method and purified using a silica-gel column and TLC. The active component was identified as 3-O:-[2'-O-(alpha-D-glucopyranosyl)- 6'-O-acyl-alpha-D-glucopyranosyl]-1,2-di-O- acyl-sn-glycerol (GAGDG) using (1)H- and (13)C-NMR and GC-MS. The compositions of the major saturated fatty acids were nC (14) (17.8%), isoC(14) (10.7%) and nC (16) (34.9%) as determined by GC-MS. The amounts of unsaturated species were less than 10% of those of the corresponding saturated acids. GAGDGs which have three tetradecanoyl groups were synthesized. These synthetic GAGDGs, as well as GAGDGs derived from A. laidlawii membranes, had a high binding affinity for MOLT-4 and HUT-78 (human T cell lines), Raji (a B cell line), HL-60 (a monoblastoid cell line) and primary cultured human T cells. The binding affinities of GAGDGs with an isoC(14) acyl group was higher than those with nC(14) and nC(16) acyl groups. The binding to lymphoid cells reveals a novel biological activity of GAGDGs.  (+info)

Survival of frozen mycoplasmas. (6/194)

Cooling to -70 C killed a higher percentage of Acholeplasma laidlawii and Mycoplasma mycoides var. capri cells than cooling to -20 C. However, to preserve cell viability for prolonged periods storage at -70 C was much more preferable. The percentage of cells surviving freezing could be increased by increasing the initial cell concentration or by the addition of dimethyl sulfoxide or glycerol as cryoprotective agents. In the presence of 1.5 M of any one of these agents survival rates of up to 100% could be obtained. The optimal cooling rates for maximal survival of A. laidlawii under the experimental conditions tested were 11 C/min for cooling to -20 C and about 15 C/min for cooling to -70 C. Increasing the warming rate during thawing from 0.6 to 67 C/min increased survival by 3 log. Oleic acid enrichment of A. laidlawii membrane lipids, or reduction in the cholesterol content of M. mycoides var. capri membranes, increased the percentage of organisms surviving freezing. Hence, the composition of membrane lipids appears to have a marked influence on the susceptibility of mycoplasmas to freezing injury.  (+info)

Reduced nicotinamide adenine dinucleotide oxidase activity in membranes and cytoplasm of Acholeplasma laidlawii and Mycoplasma mycoides subsp. capri. (7/194)

The properties of the membrane-bound reduced nicotinamide adenine dinucleotide (NADH) oxidase of Acholeplasma laidlawii were compared with those of the corresponding cytoplasmic activity of Mycoplasma mycoides subsp. capri. The striking differences in pH optima, susceptibility to inhibitors and detergents, and heat inactivation between the NADH oxidase activity, with oxygen as an electron acceptor, and the NADH oxidoreductase activity, with dichlorophenol indophenol (DCPIP) as an alternate electron acceptor, support the presence of more than one catalytic protein in both the membrane-bound and soluble enzyme systems. The detection of more than one band positive for the NADH-nitroblue tetrazolium oxidoreductase reaction on electrophoresis of either the membranes of A. laidlawii or the cytoplasm of M mycoides subsp. capri also points in the same direction. The membrane-bound enzyme system differed, however, form the soluble one because it had a lower ratio of oxidase activity to oxidoreductase activity, and because it was less susceptible to heat inactivation and more readily incorporated incorporated into reaggregated membranes. In addition, the specific activity of the membrane-bound enzyme system increased as the culture aged, whereas that of the soluble system decreased as the culture aged. It is suggested that the different location in the cell could be responsible for some of the differences between the membrane-bound NADH oxidase activity of A. laidlawii and that found in the cytoplasm of M. mycoides subsp. capri.  (+info)

Microcalorimetric detection of growth of Mycoplasmatales. (8/194)

A static ampoule microcalorimeter was used to study the growth of mycoplasmas, acholeplasmas and ureaplasmas. Growth as indicated by thermograms was compared with the results of conventional methods, namely, terminal dilution counts, plate counts, turbidimetric measurements, glucose consumption and pH changes. Removal of oxygen had little effect on mycoplasma growth. The microcalorimetric method is potentially useful for identifying and enumerating the members of the Mycoplasmatales.  (+info)

The effect of rifampin on the replication of MVL51, a bullet-shaped mycoplasmavirus with single-stranded circular DNA of molecular weight 2 X 10(6), has been examined in a rifampin-resistant host cell. Rifampin does not block the early steps in MVL51 infection but does decrease the total amount of parental viral DNA taken up. The single-stranded parental viral DNA that enters the cell is found in membrane-associated, double-stranded DNA replicative forms I and II. Rifampin had no significant effect on the synthesis of progeny viral DNA RFI and RFII early in infection and SSI (single-stranded progeny viral chromosomes) later in infection. The rifampin block in virus synthesis was found to be in the step converting SSI into assembled virions. Rifampin was shown to affect the synthesis of virus-specific RNA, Which suggests that viral transcription is necessary for virion assembly. ...
The study of the phase equilibria involving formaldehyde is still relevant because of its presence in new processes where biomass is the raw material. The coupling between physical phase equilibria and chemical reactions makes its thermodynamic description a challenging task. In this work, an improved approach using UNIQUAC coupled to chemical equilibria was developed and compared with experimental data from the literature. The first application was done for the phase equilibria of the formaldehyde-water system and distribution of oligomers in the liquid phase was computed. The second and the third applications respectively considered the phase equilibria of the formaldehyde-methanol system and the formaldehyde-water-methanol system. ...
The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models.. A monotopic membrane protein, monoglucosyldiacylglyecerol synthase (MGS) from Acholeplasma laidlawii is known to induce intracellular vesicles when expressed in Escherichia coli. The mechanism leading to this unusual phenomenon was investigated by various biochemical and biophysical techniques. The results indicated a doubling of lipid synthesis in the cell, which was triggered by the selective binding of MGS to anionic lipids. Multivariate data analysis revealed a good correlation with MGS production. Furthermore, preferential anionic lipid sequestering by MGS was shown to induce a different fatty acid modeling of E. coli membranes. The roles of specific lipid binding and the probable mechanism leading ...

The adsorption of mycoplasma virus P1, a virus which infects some strains of Mycoplasma pulmonis, to host cells was examined. Mutants of M. pulmonis to which P1 virus did not adsorb were isolated. Proteins from the mutants and from wild-type cells were compared by two-dimensional polyacrylamide gel electrophoresis, and the only observed difference was in the surface antigen V-1. The electrophoretic properties of V-1 also correlated with the host range of the virus. These data strongly suggest that the V-1 antigen affects adsorption of P1 virus to host cells ...

The initial phase of the project involved an investigation into the modeling of binary carboxylic acid vapour-liquid equilibrium (VLE) data. This stemmed from the Masters research that led into the current study, in which the conventional gamma-phi formulation of VLE was found to inadequately describe the complicated acid chemistry. In an effort to correctly describe the dimerization occurring in both the liquid and vapour phases, the chemical theory of vapour-phase imperfections was applied. The chemical theory technique allowed the experimental liquid-phase activity coefficients to be accurately calculated by taking the vapour phase dimerization into account. Once these activity coefficients had been determined, standard Gibbs excess energy models were fitted to permit analysis of the VLE datas thermodynamic consistency. In addition, the typical bubble-point iteration scheme used for VLE data regression was adapted to include the chemical theory expressions necessary for satisfactory modeling ...
The activities of methanol, ethanol, 2-propanol, and 1-butanol in poly(ethylene glycol) methacrylate (Mn = 360) solutions have been measured by the isopiestic method at 298.15 K. Sodium iodide and calcium chloride were used as the isopiestic standards for the calculation of activities. The original equation of Flory−Huggins and the modified Flory−Huggins equation with concentration-dependent interaction parameters have been used for the correlation of the experimental solvent activity data. The strength of interaction between different alcohols and the polymer was discussed on the basis of the obtained Flory−Huggins interaction parameters. The reliability of the two local-composition models, NRTL and NRF, were also assessed by fitting the experimental activity data to these models. All of these models satisfactorily present the obtained experimental activity data. ...

In the Lg or Lp phase, an axially symmetric powder pattern of about 100-ppm breadth is observed, and this transforms to an isotropic line at the main Lβ (Lβ) →Lα phase transition. In the case of DPPE, this transformation occurs precipitously and, with data from 2H spectra of 2H chain labeled DPPE, is shown to be due to a change in conformation at the sn-2 carbonyl. In contrast, the 13C=0 sn-2 spectra of lecithins exhibit a gradual transformation, beginning at ...
Crystallisation experiments have been performed on white phonolitic pumice samples of the Mercato (8010 BP), Avellino (3360 BP), Pompei (79 AD), and Pollena (472 AD) eruptions of Vesuvius to determine how the addition of sulphur to the system changes phase equilibria and compositions with respect to the sulphurfree system (experiments being undertaken by B. Scaillet and co-workers); the goal being to better constrain the pre-eruption conditions in the magma chamber preceding major phonolitic eruptions at Vesuvius, as well as to constrain the atmospheric sulphur yields of these eruptions. The experiments have been performed in an IHPV with a hydrogen membrane at 200 MPa, a maximum temperature of 930 °C, ƒO2 between NNO-4 and NNO+2, with 1 wt% S added to half of the capsules.

Solution and solid-state properties of m-hydroxybenzoic acid have been investigated. Two polymorphs were found where the monoclinic modification exhibits a higher stability than the orthorhombic form. The solubility of the monoclinic polymorph was determined between 10 and 50 degrees C in methanol, acetonitrile, acetic acid, acetone, water and ethyl acetate. The solubility of the orthorhombic polymorph was determined between 10 and 50 degrees C in acetonitrile, acetic acid, acetone and ethyl acetate. A thermodynamic analysis revealed a marked correlation between the molar solubility and the vant Hoff enthalpy of solution at constant temperature. In addition, in each solvent increased temperature resulted in increased vant Hoff enthalpy of solution. It is shown that the solubility data can be used to estimate melting properties for both polymorphs. The solubility ratio of the two forms and the DSC thermogram of the orthorhombic form strongly suggest that the system is monotropic. However, ...

So now were starting to look at mixtures. And so now we have more than one constituent. And we have more than one phase present. Right? So youve started to look at things that look like this, where youve got, lets say, two components. Both in the gas phase. And now to try to figure out what the phase equilibria look like. Of course its now a little bit more complicated than what you went through before, where you can get pressure temperature phase diagrams with just a single component. Now we want to worry about whats the composition. Of each of the components. In each of the phases. And whats the temperature and the ...

Graphical shortcut methods are useful tools for the design of distillation columns. The proposed nonideal shortcut method includes a graphical representation and is based on the concept of operation leaves. This new method uses a production segment rather than a completely specified product, which eliminates any sensitivity to the composition of the minor product. Concerning phase equilibria, no restrictive assumptions are made. - The study aimed (1) to determine whether a specified separation respects the mass balance and thermodynamic feasibility and (2) to find the minimum reflux ratio for a preliminary design of the column. Designs obtained with this new method for ideal, non-ideal, and azeotropic mixtures give purity and recovery rates close to the specifications, which might be impossible to obtain with a conventional ideal shortcut like the well-known Fenske-Underwood-Gilliland shortcut method. The distillation boundaries of azeotropic mixtures are taken into account thanks to a non-ideal ...

Plasmaviridae is a family of bacteria-infecting viruses. Acholeplasma species serve as natural hosts. There are currently only one genus (Plasmavirus), and one species in this family: the type species Acholeplasma phage L2. All species known in this family have been isolated from species in the class Mollicutes. This family is poorly studied and little is known about these viruses. The family has one genus, Plasmavirus, which has one recognized member. There are five tentative members of Plasmavirus: Acholeplasma phage L2 (type species) Mycoplasmatales virus-laidlawii 1 (L1) (tentative) Mycoplasmatales virus-laidlawii 2 (L2) (tentative) Mycoplasmatales virus-laidlawii 3 (L3) (tentative) Mycoplasmatales virus-laidlawii 51 (L51) (tentative) Mycoplasmatales virus-laidlawii O1 (O1) (tentative) Group: dsDNA Order: Unassigned Family: Plasmaviridae Genus: Plasmavirus Acholeplasma phage L2 The genome is condensed, nonsegmented and consists of a single molecule of circular, supercoiled double-stranded ...

TY - JOUR. T1 - Phase equilibria for the mixtures of supercritical methanol + C18 methyl esters and supercritical methanol + α-tocopherol. AU - Fang, Tao. AU - Shimoyama, Yusuke. AU - Abeta, Toshio. AU - Iwai, Yoshio. AU - Sasaki, Mitsuru. AU - Goto, Motonobu. PY - 2008/12/1. Y1 - 2008/12/1. N2 - Phase equilibrium data for methanol + C18 methyl esters and methanol + α-tocopherol were measured at 523-573 K in the pressure ranges of 2.45-11.45 MPa for C18 methyl esters and 3.19-15.02 MPa for α-tocopherol, respectively. The measured data were correlated using Peng-Robinson equation of state (PR EOS) with conventional mixing rules. The distribution coefficients of C18 methyl esters and α-tocopherol in methanol were discussed. The data illustrate that when the pressure is lower than the critical pressure of methanol (8.097 MPa), the mole fractions of methanol in vapor are very close to unity for both systems. When the pressure increased over 8 MPa, the distribution coefficients increased ...

Mycoplasmas are unique microorganisms. They are the smallest known free-living and self-replicating prokaryotes and are distinct from gram-negative and gram-positive bacteria by the lack of a rigid cell wall. Mycoplasmas and bacterial L-forms reveal a similar colony appearance (i.e., a fried-egg colony morphology) but have no close relationship, as genomic analyses has shown. Mycoplasmas can be found in animals, humans, plants, and insects. Some mycoplasmas are well described as pathogens; others have been discussed as cofactors, opportunists, or commensals.

The first part of the research work was devoted to establish a self-consistent thermodynamic database of relevant components (La-Sr-Co-Fe-O) using the CALPHAD (CALculation of PHAse Diagrams) approach. Published thermodynamic databases and experimental data related to the La-Sr-Co-Fe-O system were critically reviewed. The thermodynamic descriptions of the La-Co-O, Sr-Co-O and La-Sr-Co-O systems were further improved in order to construct the present thermodynamic database for LSCF, while new thermodynamic modeling of the Co-Fe-O, Sr-Co-Fe-O and La-Sr-Co-Fe-O systems was performed in this work. Calculated phase equilibria in LSCF as functions of composition, temperature, oxygen partial pressure are discussed by comparing with experimental data. Based on the developed thermodynamic database, the stability windows of LSC (La1−xSrxCoO3−δ) and LSCF are predicted and presented in Chapter 5 and Chapter 6, respectively. Calculations show that the perovskite phase is stable at high La and Fe ...
Fifty years ago solution chemistry occupied a major fraction of physical chemistry textbooks, and dealt mainly with classical thermodynamics, phase equilibria, and non-equilibrium phenomena, especially those related to electrochemistry. Much has happened in the intervening period, with tremendous advances in theory and the development of important new experimental techniques.

The design of processes containing information on phase equilibria must be carried out through a series of steps, experimentation ↔ verification ↔ modeling ↔ simulation. Each of these steps should be rigorously performed to guarantee a good representation of the behavior of the system under study, whose adequate modeling could be used to simulate the corresponding process. To carry out the different previous tasks, two representative systems, extracted from known database, are used. The quality checking of experimental data series is certified through several thermodynamic consistency methods. The modeling is done by applying a multi-objective optimization procedure, which allows to define a solution front (Pareto front) for different sub-models that are established in this work. The fitness of trade-off solutions, obtained from the efficient front, on the design of distillation processes is analyzed through a simulation.
