Using the full stoichiometry of all biochemical conversions that take place during formation of biomass, plus taking into account the energy expenditure for synthesis processes and essential transport, the model computes exactly the weight of biomass produced from a certain quantity of glucose, plus a N source, plus minerals. Simultaneously, the weight of the H2O and CO2 produced, plus the weight of O2 consumed is found. The model can be applied for the full range of biochemical compositions of plant and animal biomass. The model is a static simulation program.
Purpose of the model:
Model parentage: Results used in BACROS* and SUCROS*.
