Expression data from Bifidobacterium animalis ssp. lactis strains exposed to hydrogen peroxide stress

Stress survival tactics in bacteria utilize the up- and down-regulation of stress response genes. In bacteria that lack classical stress response genes for oxidative stress, other cellular systems can be used for cell survival. We used custom microarrays to study the regulation of genes in Bifidobacterium animalis ssp. lactis strains to oxidative stress to elucidate novel stress response mechanisms.
