Schematic diagram for proposed production of bio-nylon 510 using purified cadaverine obtained from the pyridoxal pyrophosphate (PLP)- and isopropyl β-d-1-thiogalactopyranoside (IPTG)-free whole cell bioconversion of l-lysine, which is catalyzed by recombinant E. coli strains expressing a lysine decarboxylase from H. alvei and E. coli.
