Surface Treatment of Bulk meso-carbon by Oxidizing and Non-oxidizing Gas Plasma

Variable carbon isotope fractionation expressed by aerobic CH4-oxidizing bacteria

Carbon isotope fractionation factors reported for aerobic bacterial oxidation of CH4 ðaCH4–CO2Þ range from 1.003 to 1.039. In a series of experiments designed to monitor changes in the carbon isotopic fractionation of CH4 by Type I and Type II methanotrophic bacteria, we found that the magnitude of fractionation was largely due to the first oxidation step catalyzed by methane monooxygenase (MMO...

SrTiO3(001) surface structures under oxidizing conditions

The thermodynamically stable (2 1), c(4 2) and c(6 2) surface structures were obtained under oxidative conditions on the SrTiO3(0 0 1) surface and studied with transmission electron microscopy. All three reconstructed surfaces exhibit similar morphological features––formation of flat h100i facets on the surface, stabilization of h110i originally polar facets as well as the existence of surface ...

Investigation of the Excess Sludge Reduction in SBR by Oxidizing Some Sludge by Ozone

The excessive biological sludge production is one of the disadvantages of aerobic process such as SBR. So the problem of excess sludge production along with its treatment , and disposal in aerobic processes in municipal and industrial waste water can be seen in many parts of the world even in our country . to solve the problem of excess sludge production , reducing in by oxidizing some of t...

cumA multicopper oxidase genes from diverse Mn(II)-oxidizing and non-Mn(II)-oxidizing Pseudomonas strains.

A multicopper oxidase gene, cumA, required for Mn(II) oxidation was recently identified in Pseudomonas putida strain GB-1. In the present study, degenerate primers based on the putative copper-binding regions of the cumA gene product were used to PCR amplify cumA gene sequences from a variety of Pseudomonas strains, including both Mn(II)-oxidizing and non-Mn(II)-oxidizing strains. The presence ...
