How Stable Is Stable? Function versus Community Composition
ABSTRACT The microbial community dynamics of a functionally stable, well-mixed, methanogenic reactor fed with glucose were analyzed over a 605-day period. The reactor maintained constant pH andExpand

Flexible Community Structure Correlates with Stable Community Function in Methanogenic Bioreactor Communities Perturbed by Glucose
ABSTRACT Methanogenic bioreactor communities were used as model ecosystems to evaluate the relationship between functional stability and community structure. Replicated methanogenic bioreactorExpand

Monitoring of the anaerobic methane fermentation process
The anaerobic methane fermentation process is being used more frequently for the treatment of liquid wastes. This is primarily due to the newer technologies that are able to realize the advantages ofExpand

The effect of heavy metals on methane production and hydrogen and carbon monoxide levels during batch anaerobic sludge digestion
Abstract Heavy metals can cause upset in the anaerobic digestion of municipal sludges. Using serum bottle assays, the impact of three transition heavy metals—copper, zinc and cadmium on methaneExpand

Bioreactive Barriers: A Comparison of Bioaugmentation and Biostimulation for Chlorinated Solvent Remediation
A side-by-side comparison of bioaugmentation, biostimulation, and a recirculation-only control was implemented in a chloroethene-contaminated aquifer. The objective was to develop a contaminant massExpand

Anesthetic‐induced Preconditioning: Previous Administration of Isoflurane Decreases Myocardial Infarct Size in Rabbits
Background: Experimental evidence suggests that ATP‐sensitive potassium channels are involved in myocardial ischemic preconditioning. Because some pharmacologic effects of isoflurane are mediated byExpand

Parallel Processing of Substrate Correlates with Greater Functional Stability in Methanogenic Bioreactor Communities Perturbed by Glucose
ABSTRACT Parallel processing is more stable than serial processing in many areas that employ interconnected activities. This hypothesis was tested for microbial community function using twoExpand

Bacterial community fingerprinting of amplified 16S and 16–23S ribosomal DNA gene sequences and restriction endonuclease analysis(ARDRA)
The 16S and 23S rRNA genes have been utilized for phylogenetic analysis of both prokaryotic and eukaryotic organisms (see Section 3). In addition to direct comparison of the nucleic acid sequencesExpand

Pilot-scale in situ bioremedation of uranium in a highly contaminated aquifer. 2. Reduction of u(VI) and geochemical control of u(VI) bioavailability.
In situ microbial reduction of soluble U(VI) to sparingly soluble U(IV) was evaluated at the site of the former S-3 Ponds in Area 3 of the U.S. Department of Energy Natural and AcceleratedExpand

Pilot-scale in situ bioremediation of uranium in a highly contaminated aquifer. 1. Conditioning of a treatment zone.
To evaluate the potential for in situ bioremediation of U(VI) to sparingly soluble U(IV), we constructed a pilot test facility at Area 3 of the U.S. Department of Energy Natural and AcceleratedExpand
