Two species of obligately anaerobic mycoplasmas were the major components of a methanogenic glucose-limited enrichment culture. In pure culture, one of these organisms, tentatively named Anaeroplasma sp. strain London, was shown to be responsible for the fermentation of glucose to fatty acids, hydrogen, and carbon dioxide; the other mycoplasma was shown to produce methane from hydrogen and carb...

A novel scoring function to estimate protein-ligand binding affinities has been developed and implemented as the Glide 4.0 XP scoring function and docking protocol. In addition to unique water desolvation energy terms, protein-ligand structural motifs leading to enhanced binding affinity are included: (1) hydrophobic enclosure where groups of lipophilic ligand atoms are enclosed on opposite fac...

The stable isotope ratios of a seized pathogen culture could potentially reveal information about the environment in which the agent was produced. In this paper we describe general relationships between stable isotopes of carbon, nitrogen, and hydrogen in bacteriological culture media and spores of Bacillus subtilis, an endospore-forming soil bacterium. In numerous media that varied both in nut...

Developing catalysts that provide the effective activation of hydrogen and selective absorption of substrate on metal surface is crucial to simultaneously improve activity and selectivity of hydrogenation reaction. Here we present an unique in situ etching and coordination synthetic strategy for exploiting a functionalized metal-organic framework to incorporate the bimetallic platinum-nickel fr...

To maximise power density practical gas turbine combustion systems have several injectors which can lead to complex interactions between flames. However, our knowledge about the effect of flame-flame on flame response, essential element predict stability a combustor, is still limited. The present study investigates hydrogen enrichment, interaction, confinement, and asymmetries linear non-linear...

Abstract Ultra-thin amorphous carbon (a-C) films are well established protective coatings of optical fibers. These allow one to prevent degradation the SiO 2 fiber, which occurs due diffusion water and hydrogen molecules into cladding core. The a-C typically contain impurities, such as oxygen hydrogen, attached organic moieties via chemical bonding. formation hydrogen- oxygen-containing functio...

Due to limited reserves of bauxite, nepheline can be used in the industrial production alumina Kazakhstan. The most promising deposit is syenites Kubasadyr deposit. Currently, there no effective technology for processing ores. High energy intensity, capital intensity and significant emissions into atmosphere are main drawbacks conventional ore by sintering method. Efficient hydrochemical requir...

In this present work, simulations of 20 kW furnace were carried out with hydrogen-enriched methane mixtures, to identify optimal geometrical configurations and operating conditions operate in flameless combustion regime. The objective work is show the advantages for fuels limits current typical industrial designs these mixtures. performances a semi-industrial chamber equipped self-recuperative ...

Liquid-to-gas mass transfer in anaerobic processes was investigated theoretically and experimentally. By using the classical definition of kLa, the global volumetric mass transfer coefficient, theoretical development of mass balances in such processes demonstrates that the mass transfer of highly soluble gases is not limited in the usual conditions occurring in anaerobic fermentors (low-intensi...

An interesting case of extreme specificity of enrichment and selective culture procedures has recently been described for methane-utilizing bacteria (Leadbetter and Foster, 1958). Obligate methane-utilizing pseudomonads (Pseudomonas methanica) invariably were obtained from inocula from a great many natural sources. A further degree of specificity within the group was encountered; it was found t...
