- Cadaverine is used for the synthesis of the novel bio-polyamides 54, 56, and 510. Here, we examine the feasibility of using a lysine decarboxylase (LdcC) from Escherichia coli for high-level production of cadaverine. After sequential optimization of whole-cell biotransformation conditions, recombinant E. coli-overexpressing LdcC (EcLdcC) could produce 1.0 M cadaverine from 1.2 M crude l-lysine solution after 9 h. EcLdcC retained a higher cadaverine yield after being reused 10 times at acidic and alkaline pH values than that of a recombinant E. coli strain overexpressing an inducible lysine decarboxylase (CadA), a conventional cadaverine producer (90 vs. 51% at pH 6 and 55 vs. 15% at pH 8). This study reveals that EcLdcC is a promising whole-cell biocatalyst for the bio-based production of cadaverine from industrial grade l-lysine in comparison to EcCadA. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
