PA production from amino acids degradation in anaerobic fermentation. Experiments were performed in serum bottles with strains harbouring empty plasmid (PBAD) and the sbm operon genes (SBM). a Total glucose consumption and final organic acids profile for control strain (CTRL, no plasmid). b Total glucose consumption and final organic acid profile for cultures supplemented with valine (VAL). c Total glucose consumption and final organic acids profile for cultures supplemented with isoleucine (ILE). d Total glucose consumption and final organic acids profile for cultures supplemented with threonine (THR). e Total amino acids consumption and final PA and 1-propanol concentration. Data correspond to the average of two replicates
