Leaf-wax n-alkanes record the plant-water environment at leaf flush.
Leaf-wax n-alkanes (2)H/(1)H ratios are widely used as a proxy in climate reconstruction. Although the broad nature of the relationship between n-alkanes δ(2)H values and climate is appreciated, the quantitative details of the proxy remain elusive. To examine these details under natural environmental conditions, we studied a riparian broadleaf angiosperm species, Populus angustifolia, growing o...
متن کاملHydrogen isotope fractionation during H
Hydrogen metabolism was studied in the anaerobic bacterium, Sporomusa sp. strain DMG 58, by measuring natural abundance levels of deuterium in H 2 , H 2 O, and individual fatty acids during acetogenic growth on H 2 / CO 2 . Four cultures were grown, each in medium with a distinct hydrogen-isotopic composition ( δ D-H 2 O). The δ D value of H 2 was quantified in the residual gas exiting the grow...
متن کاملCarbon isotope fractionation during aerobic biodegradation of n-alkanes and aromatic compounds in unsaturated sand
Microcosm experiments were conducted to quantify carbon isotope fractionation during aerobic biodegradation of n-alkanes (from C3 to C10) and monoaromatic hydrocarbons in unsaturated alluvial sand. In single compound experiments with n-alkanes, the largest enrichment factor was obtained for propane ( 10.8 ± 0.7‰). The magnitude of the enrichment factor decreased with increasing number of carbon...

متن کاملHydrogen isotope fractionation in methane plasma.
The hydrogen isotope ratio (D/H) is commonly used to reconstruct the chemical processes at the origin of water and organic compounds in the early solar system. On the one hand, the large enrichments in deuterium of the insoluble organic matter (IOM) isolated from the carbonaceous meteorites are interpreted as a heritage of the interstellar medium or resulting from ion-molecule reactions taking ...
