Evaluation of organic fractions of municipal solid waste as renewable feedstock for succinic acid production

Table 4 Fermentation efficiency of A. succinogenes fed-batch cultures carried out using OFMSW hydrolysate

Initial and consumed carbon sources (g/L)^a	Nitrogen source (g/L)	MgCO₃ (g/L)	Succinic acid (g/L)	Yield (g/g)^a	Productivity (g/L/h)	By-product: succinic acid (g/g)
