Linking specific heterotrophic bacterial populations to bioreduction of uranium and nitrate in contaminated subsurface sediments by using stable isotope probing.
Shifts in terminal electron-accepting processes during biostimulation of uranium-contaminated sediments were linked to the composition of stimulated microbial populations using DNA-based stable isotope probing. Nitrate reduction preceded U(VI) and Fe(III) reduction in [¹³C]ethanol-amended microcosms. The predominant, active denitrifying microbial groups were identified as members of the Betapro...
متن کاملMicroscale distribution of cesium sorbed to biotite and muscovite.
Individual 1-3 mm biotite and muscovite clasts from Hanford sediment were contacted with 0.08 M CsNO3. They were examined using electron or X-ray microprobe methods, as intact specimens or sectioned perpendicular to their basal planes. Cs+ was observed to preferentially sorb to mica edges, steps on mica surfaces, or fractured regions. The localization of Cs conformed to hypothesized strong bind...
متن کاملSignificant effect of sorbed water on the electrical and dielectric behavior of graphite oxide
This paper reports the unexpectedly strong effect of 4 wt% additional sorbed water on the electrical and dielectric properties (50 Hze2 MHz) of graphite oxide (GO) containing 18 wt% sorbed water. Water contents of 18 and 22 wt% (designated GO18 and GO22, respectively) are compared, with the former obtained by heating at 60 C (3 h) immediately before testing. The additional water increases the c...
متن کاملAuroral boundary correlations between UVI and DMSP
[1] Equatorward and poleward auroral boundaries from latitude profiles of Polar Ultraviolet Imager (UVI) auroral images were correlated with over 23,000 boundaries derived from 2 years of Defense Meteorological Satellite Program (DMSP) electron precipitation data. Latitude differences between DMSP and UVI boundaries were averaged into 1-hour and 3-hour sectors of magnetic local time (MLT). The ...
متن کاملBiodegradation of sorbed chemicals in soil.
Rates of biodegradation of sorbed chemicals are usually lower in soil than in aqueous systems, in part because sorption reduces the availability of the chemical to microorganisms. Biodegradation, sorption, and diffusion occur simultaneously and are tightly coupled. In soil, the rate of biodegradation is a function of a chemical's diffusion coefficient, sorption partition coefficient, the distan...
