| Outline of Final Research Achievements |
To clarify the carotenoid-centered oxidative stress response mechanism in lactic acid bacteria (LAB), effects of aerobic culture condition on gene expressions and metabolites in carotenoid-producing Enterococcus gilvus was investigated using whole-transcriptome and metabolome analysis. It turned out that aerobic culture condition increased the level of gene expression of isoprenoid biosynthesis pathway, converting Acetyl-CoA to carotenoid via mevalonate, and metabolites related to Acetyl-CoA biosynthesis. These results indicate that isoprenoid biosynthesis pathway, which could be induced by aerobic condition, plays an important role in oxidative stress response mechanisms in LAB.
