Carbon conversion efficiency and population dynamics of a marine algae-bacteria consortium growing on simplified synthetic digestate: First step in a bioprocess coupling algal production and anaerobic digestion

▸ Carbon conversion efficiency of marine microalgae growing on a synthetic anaerobic digestate was 4%. ▸ Carbon conversion efficiency increased to 6.3% when bacteria were included into the carbon budget. ▸ Bacteria recycled the carbon lost during photosynthesis and originated from anaerobic digestion.
