Abstract excerpt
During industrial processes, the dairy organism Streptococcus thermophilus is exposed to stress conditions. Its ability to survive and grow in an aerobic environment indicates that it must possess defensive mechanisms against reactive oxygen species. To identify the genes involved in oxidative stress defence, a collection of mutants was generated by random insertional mutagenesis and screened for menadione...
