Streptococcus thermophilus is a facultative anaerobic bacterium that has the ability to grow and survive in aerobic environments, but the mechanism for this remains unclear. In this study, theefeB gene, encoding a dye-decolorizing peroxidase, was identified in the genome ofStreptococcus thermophilus CGMCC 7.179, and purified EfeB was able to decolorize reactive blue 5. Strikingly, genes encoding two components (TatA and TatC) of the twin-arginine translocation (TAT) system were also found in the same operon with theefeB gene. Knocking outefeB ortatC resulted in decreased growth of the strain under aerobic conditions, and complementation of theefeB -deficient strains with theefeB gene enhanced the biomass of the hosts only in the presence of thetatC gene. Moreover, it was proved for bothS. thermophilus CGMCC 7.179 andEscherichia coli DE3 that EfeB could be translocated by the TAT system ofS. thermophilus . In addition, the transcriptional levels ofefeB andtatC increased when the strain was cultured under aerobic conditions. Overall, these results provide the first evidence that EfeB plays a role in protecting cells ofS. thermophilus from oxidative stress, with the assistance of the TAT system.
