Table 4 Cell recycling analysis during solventogenic phase showing lowering of biomass yield and increased solvent yield

From: Capturing the response of Clostridium acetobutylicumto chemical stressors using a regulated genome-scale metabolic model

	Wild type (0.32 h⁻¹)		Cell recycle (0.17 h⁻¹)
Metabolites	Lower flux bound	Upper flux bound	Lower flux bound	Upper flux bound
Ammonia	−2.94	−2.94	−2.35	−2.35
Phosphate	−0.37	−0.37	−0.30	−0.30
Ethanol	8.39	8.73	6.92	10.00
Butanol	0.00	0.52	0.00	4.04
Acetone	0.00	0.20	0.00	1.52

All the values represent production flux ranges with units of mmol gDW⁻¹ h⁻¹. Negative values indicate consumption instead of production. The numbers in parentheses indicate the maximum growth rate values. The solvent fluxes were converted to C mmol units to compare the overall solvent yields.
