“…In recent years, we explored the potential of the Gram-positive diderm bacterium Corynebacterium glutamicum as a host for recombinant bacteriocin production ( Goldbeck et al, 2021 ; Desiderato et al, 2022 ; Weixler et al, 2022 ; Christmann et al, 2023 ). Due to its long history as a biotechnological platform organism, many genetic tools, cheap and defined minimal media and industrial-scale processes are established ( Becker et al, 2018 ; Wolf et al, 2021 ; Lee and Jeong, 2022 ). C. glutamicum has several advantages for recombinant bacteriocin production, e.g., the GRAS (generally regarded as safe) status, low extracellular protease activity ( Vertès, 2013 ) and functional protein secretion pathways ( Freudl, 2018 ).…”
