The high growth rate of  Ulva  seaweeds makes it a potential algal biomass resource. In particular,  Ulva meridionalis  grows up to fourfold a day. Here, we demonstrated strong carbon fixation by  U. meridionalis  using  13 C stable isotope labelling and traced the  13 C flux through sugar metabolites with isotope-ratio mass spectrometry (IR-MS), Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS),  13 C-nuclear magnetic resonance spectrometry ( 13 C-NMR), and gas chromatography-mass spectrometry (GC–MS).  U. meridionalis  was first cultured in  13 C-labelled enriched artificial seawater for 0–12 h, and the algae were collected every 4 h.  U. meridionalis  grew 1.8-fold (dry weight), and the  13 C ratio reached 40% in 12 h, whereas  13 C incorporation hardly occurred under darkness. At the beginning of the light period,  13 C was incorporated into nucleic diphosphate (NDP) sugars in 4 h, and  13 C labelled peaks were identified using FT-ICR-MS spectra. Using semiquantitative  13 C-NMR measurements and GC–MS,  13 C was detected in starch and matrix polysaccharides after the formation of NDP sugars. Moreover, the 14:10 light:dark regime resulted into 85% of  13 C labelling was achieved after 72 h of cultivation. The rapid  13 C uptake by  U. meridionalis  shows its strong carbon fixation capacity as a promising seaweed biomass feedstock.
