TL;DR: Under what circumstances SIFA can be used for a qualitative or even a quantitative assessment of biodegradation in the environment is discussed, and advances in the instrumental development for stable isotope analysis are mentioned if it is important for the understanding of the application.

TL;DR: Primary features of hydrogen and carbon isotope fractionation during toluene degradation were studied to evaluate if analysis of isotope signatures can be used as a tool to monitor biodegradation in contaminated aquifers and revealed that the use of deuterium-labeled toLUene was appropriate for studying basic features of D/H isotope fractions.

TL;DR: The results imply that microbial degradation of toluene can produce a 13C/12C isotope fractionation in the residual hydrocarbon fraction under different environmental conditions.

TL;DR: Analysis of the PCR-amplified 16S rRNA gene revealed that strain OX39 affiliates with the gram-positive endospore-forming sulfate reducers of the genus Desulfotomaculum and is the first hydrocarbon-oxidizing bacterium in this genus.

TL;DR: Different types of initial reactions used by the respective bacterial strains could be linked with certain extents of stable isotope fractionation during substrate degradation.
