Hydrogen 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...
