Steering the product spectrum in high-pressure anaerobic processes: CO2 partial pressure as a novel tool in biorefinery concepts

Table 4 Physicochemical characterization of anaerobic inoculum used in experiments I and II*

Parameter	Unit	Mean ± SD
Total chemical oxygen demand (TCOD)^a	g L⁻¹	30.7 ± 0.2
Soluble COD (SCOD)	mg L⁻¹	275 ± 1.2
Total suspended solids (TSS)	g L⁻¹	15.7 ± 0.3
Volatile suspended solids (VSS)^a	g L⁻¹	15.2 ± 0.1
VSS/TSS	%	95 ± 2
Ammonium (NH₄–N)	mg L⁻¹	21.7 ± 0.2
Total phosphorous (TP)	mg L⁻¹	49.8 ± 3.8
pH	–	7.3

*Average and standard deviations calculated from technical replicates (n = 3)
^aThe high COD/VSS ratio is attributed to the presence of fats in the original inoculum, since it was treating influent containing residues from chocolate and animal feed production
