Quantitative immunologic analysis of the methanogenic flora of digestors reveals a considerable diversity. (1/5)

To determine which methanogens occur in digestors, we performed a quantitative immunologic analysis of a variety of samples. A comprehensive panel of calibrated polyclonal antibody probes of predefined specificity spectra was used. This allowed precise identification of bacteria by antigenic fingerprinting. A considerable diversity of methanogens was uncovered, much larger than previously reported, encompassing at least 14 strains of 11 species. Strategies were developed to measure the load of any given methanogen in a sample and to compare samples quantitatively. Two methanogens were found to predominate which were antigenically closely related with either Methanobacterium formicicum MF or Methanobrevibacter arboriphilus AZ. Fundamental data, probes, and methods are now available to monitor methanogenic subpopulations during digestor operation and thus learn about their respective roles and predictive significance.  (+info)

Direct characterization of methanogens in two high-rate anaerobic biological reactors. (2/5)

The methanogenic flora from two types of turbulent, high-rate reactors was studied by immunologic methods as well as by phase-contrast, fluorescence, and scanning electron microscopy. The reactors were a fluidized sand-bed biofilm ANITRON reactor and an ultrafiltration membrane-associated suspended growth MARS reactor (both trademarks of Air Products and Chemicals, Inc., Allentown, Pa.). Conventional microscopic methods revealed complex mixtures of microbes of a range of sizes and shapes, among which morphotypes resembling Methanothrix spp. and Methanosarcina spp. were noticed. Precise identification of these and other methanogens was accomplished by antigenic fingerprinting with a comprehensive panel of calibrated antibody probes of predefined specificity spectra. The methanogens identified showed morphotypes and antigenic fingerprints indicating their close similarity with the following reference organisms: Methanobacterium formicicum MF and Methanosarcina barkeri W in the ANITRON reactor only; Methanosarcina barkeri R1M3, M. mazei S6, Methanogenium cariaci JR1, and Methanobrevibacter arboriphilus AZ in the MARS reactor only; and Methanobrevibacter smithii ALI and Methanothrix soehngenii Opfikon in both reactors. Species diversity and distribution appeared to be, at least in part, dependent on the degree of turbulence inside the reactor.  (+info)

Isolation and characterization of methanogenic bacteria from landfills. (3/5)

Methanogenic bacteria were isolated from landfill sites in the United Kingdom. Strains of Methanobacterium formicicum, Methanosarcina barkeri, several different immunotypes of Methanobacterium bryantii, and a coccoid methanogen distinct from the reference immunotypes were identified.  (+info)

Shifts in methanogenic subpopulations measured with antibody probes in a fixed-bed loop anaerobic bioreactor treating sulfite evaporator condensate. (4/5)

A fixed-bed loop, high-rate anaerobic bioreactor treating sulfite evaporator condensate was sampled when it reached steady state and afterwards following perturbations during a 14-month period. By using immunotechnology, it was observed that shifts in methanogenic subpopulations occurred in association with perturbations, such as restarting and relocating the biomass into a different tank. Methanogens related to Methanobacterium bryantii MoHG and Methanobrevibacter smithii ALI were numerous throughout the observation period, while Methanosarcina mazei S6 and Methanosarcina thermophila TM1 were found in the early and late samples, respectively. Also, Methanobacterium formicicum was more numerous at the top portion of the bioreactor, while Methanobrevibacter arboriphilus AZ and DC were at the bottom. Sample formalinization required for prolonged storage proved suitable for antigen preservation.  (+info)

Diversity and population dynamics of methanogenic bacteria in a granular consortium. (5/5)

Upflow anaerobic sludge blanket bioreactor granules were used as an experimental model microbial consortium to study the dynamics and distribution of methanogens. Immunologic methods revealed a considerable diversity of methanogens that was greater in mesophilic granules than in the same granules 4 months after a temperature shift from 38 to 55 degrees C. During this period, the sizes of the methanogenic subpopulations changed with distinctive profiles after the initial reduction caused by the shift. Methanogens antigenically related to Methanobrevibacter smithii PS and ALI, Methanobacterium hungatei JF1, and Methanosarcina thermophila TM1 increased rapidly, reached a short plateau, and then fell to lower concentrations that persisted for the duration of the experiment. A methanogen related to Methanogenium cariaci JR1 followed a similar profile at the beginning, but it soon diminished below detection levels. Methanothrix rods weakly related to the strain Opfikon increased rapidly, reaching a high-level, long-lasting plateau. Two methanogens related to Methanobrevibacter arboriphilus AZ and Methanobacterium thermoautotrophicum DeltaH emerged from very low levels before the temperature shift and multiplied to attain their highest numbers 4 months after the shift. Histochemistry and immunohistochemistry revealed thick layers, globular clusters, and lawns of variable density which were distinctive of the methanogens related to M. thermoautotrophicum DeltaH, M. thermophila TM1, and M. arboriphilus AZ and M. soehngenii Opfikon, respectively, in thin sections of granules grown at 55 degrees C for 4 months. Mesophilic granules showed a different pattern of methanogenic subpopulations.  (+info)

To regulate the magnitude and the direction of the heat flux in an exchanger-based methanol evaporator of a fuel cell system, thermoelectric (TE) modules can be deployed as active heat pumps. The performance of the TE-integrated evaporator is strongly influenced by its heat exchange structure. The structure transfers the fuel cell exhaust heat to the evaporation chamber to gasify the methanol, where TE modules are installed in between to facilitate the heat regulation. In this work, firstly, a numerical study is conducted to determine the working currents and working modes of the TE heat regulators under the system working condition fluctuations and during the system cold start. A 3-dimensional evaporator model is generated in the computational fluid dynamics (CFD) code ANSYS FLUENT® by combining a compact TE model with a number of various heat exchange structure geometries. The compact TE model adopts order-reduction technique in both gridding and computing to improve the computation ...

Boiling and condensing of internal working fluids are essential heat transfer concepts which heat pipe technology relies on for transporting a large amount of heat between two distanced points effectively. Tilt angle and working fluid saturation temperature have a direct impact on how well the evaporator is flooded. This paper focuses on how the tilt angle and the working fluid saturation temperature affect the start-up heat input requirements for an S shaped axial grooved ammonia thermosyphon heat pipe. A series of experiments was performed by supplying and extracting heat to the evaporator and condenser of the thermosyphon heat pipe. Temperature of the evaporator and condenser was monitored to capture start-up behavior upon heat input. The evaporator temperature was found to be slightly elevated before the internal working fluid begins to boil. It decreased once boiling starts and initiates the thermosyphon process. The test results showed that the evaporator start-up temperature difference was

As discussed in chapter 3.4, compressor performance depends on the evaporating and condensing pressures. The saturation pressure of the evaporator determines the density of the refrigerant gas at the inlet of the compressor, thus affecting the refrigerant mass flow per compressor revolution. The total pressure difference between the evaporating and condensing sides also affects the required compressor power consumption.. The evaporator and condenser affect these pressure levels though their ability to transfer energy between the refrigerant and the secondary fluids. The evaporator operating point is the equilibrium point at which the performance of the evaporator matches the performance of the compressor. The refrigerant mass flow is determined by the compressor, and at the operating point the refrigerant is evaporated at a stable saturation temperature.. The compressor curve in Figure 6.24 has a positive slope, indicating that the available cooling capacity increases with higher evaporation ...

Hamilton Sundstrand has developed a scalable evaporative heat rejection system called the Multi-Fluid Evaporator (MFE). It was designed to support the Orion Crew Module and to support future Constellation missions. The MFE would be used from Earth sea level conditions to the vacuum of space. This system combines the functions of the Space Shuttle flash evaporator and ammonia boiler into a single compact package with improved freeze-up protection. The heat exchanger core is designed so that radial flow of the evaporant provides increasing surface area to keep the back pressure low. The multiple layer construction of the core allows for efficient scale up to the desired heat rejection rate. A full-scale unit uses multiple core sections that, combined with a novel control scheme, manage the risk of freezing the heat exchanger cores. A four-core MFE prototype was built in 2007 ...

Originally I was more sanguine about the film than about Expelled, because Ben Steins film is a clear piece of propaganda with the clear ideological aim of undermining the audiences confidence in evolution and making the case for allowing the teaching of ID in classrooms. It is at first blush much harder to find a clear ideological message, or aim, in House of Numbers. During the discussion I asked Brent several times what he was trying to achieve with the film - what his aim was. His platitudes about informed consent and trying to help the search for a system of testing that makes no mistakes at all sounded naive and unconvincing. But (and I still think this for now) whether it is because the film is not actually very well put together, or because it really wasnt made, at least initially, strictly as propaganda, I still think it poses questions that encourage the audience to think and seek out more information. If they do that, as I have done, they quite quickly find plenty of evidence to ...

  • Custom ELISA Kits, Recombinant Proteins and Antibodies can be designed, manufactured and produced according to the researcher's specifications. (
  • In order to develop methods to generate antibodies reactive to the extracellular domains of multipass plasma membrane proteins specifically expressed in malignant tumors, we examined the use of dendritic cells (DCs) for immunization. (
  • The immunized mice produced significant amounts of antibodies against these proteins. (
  • Our results suggest that DC immunization is an effective method to produce antibodies reactive to extracellular regions of plasma membrane proteins with multiple-transmembrane domains, and may be useful to develop antibody mediated antitumor therapies. (
  • In the development of antibody-mediated therapies targeted to human cancer cells, including cancer stem/progenitor cells, the extracellular domains of plasma membrane proteins specifically expressed on cancer cells are promising candidates for antigens against which to be immunized [ 1 ], but the high homology of amino acid sequences between human antigens and their homologues in animals to be immunized often hamper efficient antibody production because of immunological tolerance. (
  • In the case of cellular membrane proteins having only a single transmembrane domain, recombinant protein with the extracellular domain fused to the Ig-Fc domain has been used as immunogen in many cases to generate antibodies reactive with the extracellular region [ 2 ]. (
  • To obtain antibodies reactive to the native extracellular structure of such membrane proteins, immunization by injection of cultured cells expressing the antigen has been used [ 3 ]. (
  • Therefore, development of a simple and successful protocol for immunization against human multi-pass membrane proteins is needed in antibody-mediated cancer research. (
