Abstract
Five species of freshwater green algae, including three strains of Botryococcus braunii (two A Race, one B Race), Eudo-
rina unicocca and Volvox aureus, were cultured under controlled conditions in media containing different concentrations of
deuterium. The hydrogen isotopic ratios of lipids in the algae, including alkadienes, botryococcenes, heptadecenes, fatty
acids, and phytadiene, were measured by gas chromatography–isotope ratio-mass spectrometry (GC–IRMS) and found
to closely track water dD values. While correlation coefficients (R2) in excess of 0.99 for all lipids in all species suggest that
lipid dD values can be used to determine water dD values, hydrogen isotope fractionation was found to vary systematically
between lipids and lipid homologues within a single alga, as well as for the same lipid between species of algae. Under
similar growth conditions, two species of Chlorophyceae (Eudorina
