  1. DCW dry cell weight, WV working volume
  2. aCalculated by the CO2-fixation rate in the unit of mg L−1 h−1 divided by the biomass concentration in the unit of g DCW L−1
  3. bCalculated by multiplying the reported OD600 (17.63) by our experimentally determined dry cell weight of E. coli (0.35 g L−1 OD600 −1)
  4. cSequential photobioreactor using recycle water
