Fig. 2From: Development of high cell density Limosilactobacillus reuteri KUB-AC5 for cell factory using oxidative stress reduction approachEssential components and mechanism for respiration metabolism in lactic acid bacteria. The LAB respiratory chain comprises an electron donor, an electron carrier (menaquinones) and a terminal electron acceptor (cytochrome bd-oxidase). Heme must be added exogenously to activate the cytochrome bd-oxidaseBack to article page
