Evaluation of novel inducible promoter/repressor systems for recombinant protein expression in Lactobacillus plantarum

Abstract

We evaluated different inducible promoters, as well as an orthologous expression system, for controlled gene expression in L. plantarum. Furthermore, here we provide proof of concept for a T7 RNA polymerase based expression system for L. plantarum. Thereby we expanded the molecular toolbox for an industrial relevant and generally regarded as safe (GRAS) strain.
