SNP search in NAD+ resistent Streptococcus pneumoniae
To gain deeper insights into antibacterial mechanisms of NAD+ and bacterial adaptation, we generated and sequenced NAD+ resistant clones of Spn. For this purpose, Spn was cultivated in liquid medium with increasing concentrations (50 µM to 5 mM) of NAD+. After six passages, bacteria were plated on blood agar supplemented with 500 µM NAD+ and three clones were picked
