Quantitative detection of Clostridium tyrobutyricum in milk by real-time PCR. (1/5)

We developed a real-time PCR assay for the quantitative detection of Clostridium tyrobutyricum, which has been identified as the major causal agent of late blowing in cheese. The assay was 100% specific, with an analytical sensitivity of 1 genome equivalent in 40% of the reactions. The quantification was linear (R(2) > 0.9995) over a 5-log dynamic range, down to 10 genome equivalents, with a PCR efficiency of >0.946. With optimized detergent treatment and enzymatic pretreatment of the sample before centrifugation and nucleic acid extraction, the assay counted down to 300 C. tyrobutyricum spores, with a relative accuracy of 82.98 to 107.68, and detected as few as 25 spores in 25 ml of artificially contaminated raw or ultrahigh-temperature-treated whole milk.  (+info)

Effect of initial glucose concentrations on carbon material and energy balances in hydrogen-producing Clostridium tyrobutyricum JM1. (2/5)

The carbon metabolism of newly isolated Clostridium tyrobutyricum JM1 was investigated at varying initial glucose concentrations (27.8-333.6mM). Because an understanding of metabolic regulations was required to provide guidance for further effective metabolic design or optimization, in this case, maximizing hydrogen production, carbon material, and energy balances by C. tyrobutyricum JM1 were determined and applied in anaerobic glucose metabolism. The overall carbon distribution suggested that initial glucose concentrations had strong influence on the stoichiometric coefficients of products and the molar production of ATP on the formation of biomass. C. tyrobutyricum JM1 had a high capacity for hydrogen production at the initial glucose concentration of 222.4 mM with high concentrations of acetate and butyrate.  (+info)

Biobutanol is a sustainable green biofuel that can substitute for gasoline. Carbon flux has been redistributed in Clostridium tyrobutyricum via metabolic cell engineering to produce biobutanol. However, the lack of reducing power hampered the further improvement of butanol production. The objective of this study was to improve butanol production by rebalancing redox. Firstly, a metabolically-engineered mutant CTC-fdh-adhE2 was constructed by introducing heterologous formate dehydrogenase (fdh) and bifunctional aldehyde/alcohol dehydrogenase (adhE2) simultaneously into wild-type C. tyrobutyricum. The mutant evaluation indicated that the fdh-catalyzed NADH-producing pathway improved butanol titer by 2.15-fold in the serum bottle and 2.72-fold in the bioreactor. Secondly, the medium supplements that could shift metabolic flux to improve the production of butyrate or butanol were identified, including vanadate, acetamide, sodium formate, vitamin B12 and methyl viologen hydrate. Finally, the free-cell
Production and application of bio-based industrial products are increasingly important to the nations economic development. The goal of this work was to develop a novel bioprocess to economically produce butyric acid from low-value agricultural commodities. Butyric acid has many important applications in chemical, food, and pharmaceutical industries. Conventional fermentation technologies for butyric acid production are limited by low reactor productivity, product concentration, and yield. In this study, novel metabolic engineering approaches, at both molecular biology and process engineering levels, were developed for enhanced butyric acid production by Clostridium tyrobutyricum. First, a novel fibrous-bed bioreactor (FBB) was developed for fermentation of glucose and xylose to produce butyrate with high reactor productivity (>2.5 g/L/h), high butyrate concentration (58 g/L), and a butyrate yield of 0.47 g/g. Cells in the FBB were able to grow into high density (>70 g/L) and tolerate high ...
Carbon materials have properties different from conventional oxides in catalysis, in particular as catalyst supports. Recently, carbon nanotubes (CNTs) interest us with their well defined tubular morphology and their electron structure in the graphene walls, where π electrons shift from the inside to the outside due to the reversed curvature. This provides an intriguing confinement environment for nanocatalysts and catalytic reactions inside such small cavities. In the present talk, the unique effects of the electron confinement with CNTs and the resulted modulating in catalysis will be illustrated. The techniques to introduce metal nanoparticles homogeneously inside the CNT channels have been developed and the effects of confined metal catalysts on their physio-chemical properties, as well as their catalytic activities have been studied systematically. Using Fe as a probe, it is found that the redox properties of iron oxide and metallic iron are modified when they are confined inside the CNT ...

Got a lovely phone call today... my levels from the initial glucose test are "elevated." Now I have to go back for the three hour test. Ugh. I havent had to go through this yet. My other pregnancies showed normal levels and there was no possibility of gestational diabetes. Now I know Im older with this one and have technically crossed into my "30s" but seriously. Surely my age is not a factor. I havent done much research about gestational diabetes, so I dont know anything about markers or risks for it or anything. Honestly, I dont want to "borrow trouble" and worry about it until we cross that bridge. My test isnt until next Thursday. So, til then I will just take it day by day and continue to eat carbs and sugar! :) Whats ridiculous is how I feel baby move and wonder if its different than the last two, as if I should feel something different were I to have gestational diabetes ...
Novel metallic forms of planar carbon are described, as well as methods of designing and making them. Nonhexagonal arrangements of carbon are introduced into a graphite carbon network essentially without destroying the planar structure. Specifically a form of carbon comprising primarily pentagons and heptagons, and having a large density of states at the Fermi level is described. Other arrangements of pentagons and heptagons that include some hexagons, and structures incorporating squares and octagons are additionally disclosed. Reducing the bond angle symmetry associated with a hexagonal arrangement of carbons increases the likelihood that the carbon material will have a metallic electron structure.

Graphene is a mono-layer carbon material with low cost, high chemical/thermal stability, and ultrahigh strength and is expected to be a replacement of silicon and noble metals for electron devices, battery materials, photo-/ion detectors and catalysts. Although some of graphene products such as display and electrodes are commercially available, the applications are limited due to the 2D sheet structure. In other words, the performance per gram is excellent but the performance per volume cannot be achieved easily. Therefore, many efforts have been made to construct the 2D material as a 3D structure with retained physical/chemical properties and high volumetric performance. However, the reported 3D nanoporous carbon materials suffer from poor mobility because of the lower crystallinity, which cannot be used for the electron devices. To achieve semiconductor-grade 3D carbon materials, the monolayer graphene sheet with a high crystalline structure is required in a 3D structure. Thus, we have ...

Lactobacillus pentosus TV35b, isolated from the posterior fornix secretions of the vagina of a prenatal patient, produced a bacteriocin-like peptide (pentocin TV35b), which is inhibitory to Clostridium sporogenes, Cl. tyrobutyricum, Lact. curvatus, Lact. fermentum, Lact. sake, Listeria innocua, Propionibacterium acidipropionici, Propionibacterium sp. and Candida albicans. The mechanism of activity of pentocin TV35b is bactericidal, as shown by a decrease in the viable cell numbers of Lact. sake from approximately 4 x 108 to less than 10 cfu ml-1 over a period of 4 h. Pentocin TV35b added to the growth medium of C. albicans stimulated the formation of pseudohyphae during the first 36 h, followed by a slight repression in cell growth. Production of pentocin TV35b was at its maximum towards the end of the logarithmic growth phase of strain TV35b. The peptide was purified by ammonium sulphate precipitation, followed by SP-Sepharose cation exchange chromatography. The molecular size of pentocin TV35b ...

In this work a protocol for bright-field electron tomography in the transmission electron microscope (TEM) is developed. This protocol provides high resolution in 3D better than 1nm. It enables to study materials prone to radiolysis effects such as carbon materials. For the latter an aberration corrected TEM operated at a low acceleration voltage of 80kV is necessary to reduce the knock-on related beam damage. This protocol is exemplified on commercially available Vulcan XC-72 carbon soot particles which serve as a support for catalytically active nanoparticles (here platinum). This approach enables to visualize and quantify the internal three-dimensional graphitic nanostructure with ~0.35nm graphitic interplanar distance by layer distance, fringe length and tortuosity providing statistical measures for the 3D carbon volume. The protocol ensures that the sample withstands the entire tilt series acquisition by a minimum dose protocol. The appropriate imaging conditions are specified and ...

In this paper, wool carpet dye adsorption properties of nanoporous activated carbon materials (NCMs) prepared from bamboo agro-product is reported. Bamboo cane powder was chemically activated with phosphoric acid at different temperatures (400, 500, and 600 °C) at an impregnation ratio of 1:1. We found that the specific surface area and the total pore volume of NCM increases with temperature giving the highest surface area and pore volume ca. 2130 m2·g−1 and 2.69 cc·g−1 at 600 °C. Owing to superior surface textural properties, bamboo-derived NCM showed excellent adsorption capacity for wool carpet dyes Lanasyn orange (LO) and Lanasyn gray (LG). The adsorption phenomena could be described by Langmuir/Freundlich adsorption isotherm models. The maximum adsorption capacity was ca. 2.60 × 103 and 3.04 × 103 mg·g−1 for LO and LG, respectively. The adsorption followed pseudo second order kinetics with the second order rate constant of 1.24 × 10−3 g·mg−1·min−1 (LO) and 7.69 × 10−4 g·mg

Activated carbon particles or fabrics are coated with a deformable or water-insoluble coating material comprising a binding agent and a masking agent that can be colored. The coating material can provide sufficient diffusivity to permit excellent efficiency in adsorption of materials in spite of the presence of a coating layer on the activated carbon. The use of a deformable binding agent yields coated particles that make relatively noise when the particles flow or are moved in use, and that have improved tactile properties in use. High performance colored activated carbon materials can be produced and placed in absorbent articles, overcoming common objections about the black color of activated carbon.

N2 - In this mini-review, we report the recent research results in the molecular assemblies composed of nanoscale carbon materials such as fullerenes, carbon nanotubes (CNT) and graphenes for photoinduced electron transfer and light energy conversion. First, we state fullerene-encapsulated porphyrin nanorods for efficient photovoltaic and photocatalytic applications. The useful encapsulation of electron acceptor units within a porphyrin nanotube (reaction cavity) successfully controls the light energy conversion property under visible light irradiation. Then, photoinduced electron transferin self-assembled single-walled carbon nanotubes (SWCNT)/zinc porphyrin (ZnP) hybrids having different band gaps is reported. Furthermore, we discuss the structural and photoelectrochemical properties of similar ...
Utilizing renewable recourses and waste recycling are necessary for reaching a circular resource society. The concept of this thesis was to set up a sustainable recycling route, suitable even for low quality biopolymer and plastic waste for production of functional carbon materials. Carbonaceous materials were prepared by mild hydrothermal carbonizations of cellulose and polypropylene (PP) under acidic conditions. The carbonization of cellulose resulted mainly in micro-/nanometer sized carbon spheres (CS) with polar functionalities. After carbonization of PP, products were found in solid and liquid phase. Completely carbonized solid carbons products were obtained from PP at 250 °C after 60 min. The liquid products from the same process displayed aromatics and exhibited fluorescence properties. In addition, new carbon materials were prepared by acid, base and thermal treatments of the carbonized products at low temperatures. Thermally resistant carbon products and antibacterial CS towards both ...

In comparison to conventional silk, the carbon-enhanced silks are twice as tough and can stand up to a minimum of 50 percent greater stress before splitting. The team warmed the silk fibers at 1,050 degrees C to carbonize the silk protein and then analyzed their conductivity and structure. The altered silks were found to conduct electrical current, unlike regular silk.. "This natural feeding strategy could be easily scaled up, paving a new path for the production of supertough silk fibers at a large scale," the study said.. Spectroscopy and electron microscopy imaging revealed the carbon-enhanced silk fibers had a more structured composition as a result of incorporated nanomaterials. The carbon materials could not be seen in cross-sections of the silk threads, perhaps due to low nanoparticle content.. "It is worth noting that there are still several interesting and important questions that cannot be answered by our current work, such as what is the safety limit of nanocarbons in the diets for ...

Carbon nanomaterials have a large surface area and complex particles shape architecture. These qualities are successfully applying to develop new drug carriers, fillers, or nanodetectors [1]. At the same time, the utilization efficiency of such materials is caused by maintaining of the nanodispersity. An agglomeration and partially sedimentation of nanotubes in aqueous media is a well-known fact. The stability of the nanotube dispersion mostly depends on the uniformity of the boundary layer and nanotube morphology. The hydrophobic nature of defectless areas of their surface and the hydrophilicity of some types of defects in the nanotube boundary layer, namely carboxy- or phenolic groups [2, 3] which are formed during nanotube purification and washing, are competing during dispersing in the aqueous media. An increase in stability of the nanotube dispersion in water can be achieved through the surface charge via formation of the double electrical layer (EDL). Among other carbon materials, carbon ...
