Radiocarbon analyses of 14C in lipid biomarkers associated with marine plankton [14], and 13C - labeled bicarbonate tracer studies [15] suggest that marine Crenarchaeota are capable of light - independent autotrophic carbon assimilation into membrane lipid biomass, an hypothesis further strengthened by recent single cell phylogenetic identification and autoradiographic verification of carbon dioxide incorporation [16].
