such as Mndependent SOD and heme-dependent catalase (Chaillou et al. 2005). The L. sakei genome contains genes encoding a hemedependent catalase, a superoxide dismutase, and a NADH oxidase to cope with reactive oxygen species, and there are several systems to cope with reactive oxygen species, and there are several systems to cope with changes in the redox potential.
A summary of the main metabolic pathways used by the meat starter bacteria (Lactobacillus and Staphylococcus) is given in Figure 10.1.
