Optimized recombinant production of the bacteriocin garvicin Q by .

Bacteriocins are antimicrobial peptides applied in food preservation and are interesting candidates as alternatives to conventional antibiotics or as microbiome modulators. Recently, we established as a suitable production host for various bacteriocins including garvicin Q (GarQ). Here, we establish secretion of GarQ by via the Sec translocon achieving GarQ titers of about 7 mg L in initial fermentations.
