Metabarcoding reveals unique microbial mat communities and evidence of biogeographic influence in low‐oxygen, high‐sulfur sinkholes and springs

Ecology and Evolution, Volume 14, Issue 3, March 2024.
Groundwater‐fed underwater sinkholes and springs create habitats with high‐sulfur, low‐oxygen conditions. Multi‐marker metabarcoding was used to describe microbial mat communities in these extreme aquatic habitats. Unique bacterial and diatom communities were found in five springs in Michigan and Florida, with water parameters and biogeography ...

Experimental determination of isotope enrichment factors – bias from mass removal by repetitive sampling [PDF]

, 2016
Application of compound-specific stable isotope approaches often involves comparisons of isotope enrichment factors (ε). Experimental determination of ε-values is based on the Rayleigh equation, which relates the change in measured isotope ratios to the ...

Characterization of the Corrinoid Iron-Sulfur ProteinTetrachloroethene Reductive Dehalogenase of Dehalobacterrestrictus [PDF]

Applied and Environmental Microbiology, 2003
ABSTRACT The membrane-bound tetrachloroethene reductive dehalogenase (PCE-RDase) (PceA; EC 1.97.1.8), the terminal component of the respiratory chain of Dehalobacter restrictus , was purified 25-fold to apparent electrophoretic homogeneity. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed

Geochemical and microbial community determinants of reductive dechlorination at a site biostimulated with glycerol [PDF]

, 2016
Biostimulation is widely used to enhance reductive dechlorination of chlorinated ethenes in contaminated aquifers. However, the knowledge on corresponding biogeochemical responses is limited. In this study glycerol was injected in an aquifer contaminated

Heterologous expression, purification and cofactor reconstitution of the reductive dehalogenase PceA from Dehalobacter restrictus

Protein Expression and Purification, 2012
Organohalide respiration is used by a limited set of anaerobic bacteria to derive energy from the reduction of halogenated organic compounds. The enzymes that catalyze the reductive dehalogenation reaction, the reductive dehalogenases, represent a novel and distinct class of cobalamin and Fe-S cluster dependent enzymes.

Characterization of the electron-accepting part of the organohalide respiration chain of Dehalobacter and Desulfitobacterium

, 2022
Organohalide respiration (OHR) is a bacterial anaerobic process that use halogenated compounds, e.g. tetrachloroethene (PCE), as terminal electron acceptors. D. restrictus strain PER-K23, an obligate OHR bacterium (OHRB), and D. hafniense strain TCE1, a bacterium with a versatile metabolism, harbour the pceABCT gene cluster, which represents our model ...
