Large carbon isotope fractionation during biodegradation of chloroform by Dehalobacter cultures.
Compound specific isotope analysis (CSIA) has been applied to monitor bioremediation of groundwater contaminants and provide insight into mechanisms of transformation of chlorinated ethanes. To dateExpand
Insights into enzyme kinetics of chloroethane biodegradation using compound specific stable isotopes.
While compound specific isotope analysis (CSIA) has been used extensively to investigate remediation of chlorinated ethenes, to date considerably less information is available on its applicability toExpand
Distinct carbon isotope fractionation during anaerobic degradation of dichlorobenzene isomers.
Chlorinated benzenes are ubiquitous organic contaminants found in groundwater and soils. Compound specific isotope analysis (CSIA) has been increasingly used to assess natural attenuation ofExpand
Eukaryotic opportunists dominate the deep-subsurface biosphere in South Africa
Following the discovery of the first Eukarya in the deep subsurface, intense interest has developed to understand the diversity of eukaryotes living in these extreme environments. We identified thatExpand
Understanding and managing the re-eutrophication of Lake Erie: Knowledge gaps and research priorities
Eutrophication of freshwaters is already a problem in many regions globally and will probably worsen as human populations grow and consume more resources. The ability of researchers and governmentsExpand
Measuring Concentrations of Dissolved Methane and Ethane and the 13 C of Methane in Shale and Till.
Baseline characterization of concentrations and isotopic values of dissolved natural gases is needed to identify contamination caused by the leakage of fugitive gases from oil and gas activities.Expand
Internal return of carbon dioxide in decarboxylation: catalysis of separation and 12C/13C kinetic isotope effects.
It has been proposed that the decarboxylation of mandelylthiamin, the adduct of benzoylformate and thiamin, is uniquely catalyzed by protonated pyridines through a preassociation mechanism in whichExpand
Monitoring biodegradation of ethene and bioremediation of chlorinated ethenes at a contaminated site using compound-specific isotope analysis (CSIA).
Chlorinated ethenes are commonly found in contaminated groundwater. Remediation strategies focus on transformation processes that will ultimately lead to nontoxic products. A major concern with theseExpand
Hydrolytic decarboxylation of carboxylic acids and the formation of protonated carbonic acid.
Acid-catalyzed decarboxylation reactions of carboxylic acids should avoid formation of protonated carbon dioxide, a very high energy species. A potential alternative route parallels ester hydrolysis,Expand

The decarboxylation of pyrrole-2-carboxylic acid is subject to acid catalysis in strongly acidic solutions. Protonation of the pyrrole ring at C2 produces a potentially low-energy carbanion leavingExpand
