3D illustrations of relationships among theoretical yield, P/O ratio and non-growth associated ATP maintenance. (A) Theoretical Yield as a function of P/O ratio and non-growth associated ATP maintenance without constraining biomass growth (v(8) ≥ 0). (B) Theoretical Yield as a function of P/O ratio and non growth associated ATP maintenance at growth rate v(8) = 3.6. The units of yield and ATP maintenance are ‘g C16:0 fatty acid/g glucose’ and ‘mol ATP /g glucose’ respectively. Under certain circumstances, the energy cannot be balanced for fatty acid or biomass production, resulting zero yield [47].
