From: Flux balance analysis of primary metabolism in Chlamydomonas reinhardtii

  Biomass Formation Equation (moles/kg biomass)
  Autotrophic Mixotrophic Heterotrophic
DNA 0.002 0.002 0.002
RNA 0.051 0.051 0.051
Protein 2.005 2.328 1.706
Carbohydrate 2.008 1.513 1.752
Lipid 0.203 0.298 0.307
Chlorophyll a 0.010 0.008 0.020
Chlorophyll b 0.016 0.014 0.009
ATP (polymerization) 9.350 13.320 8.890
ATP (maintenance) 29.890 29.890 29.890
  1. Biomass formation equation given in moles per kg biomass. Protein, lipid, chlorophyll were measured independently for each growth regime. DNA and RNA content were assumed the same for all cases and carbohydrates was assumed to be the balance. Polymerization energy includes energy required for protein, RNA and DNA polymerization and maintenance is based on a fitted value for heterotrophic growth.
