Cell lysis by H‐NS K57N in wild‐type BW25113 (WT), BW25113 hha hns (hha hns), BW25113 Δrac (Δrac), BW25113 hokD (hokD) and BW25113 Δrac hokD (Δrac hokD) in LB at 37°C after 11 h. Extracellular DNA (eDNA) and intracellular DNA (iDNA) were quantified by qPCR using reference gene purA via the purA‐f and purA‐r primers. Cell lysis was calculated by dividing the amount of eDNA by the sum of eDNA and iDNA. Each data point is the average of at least four replicates from two independent cultures, and one standard deviation is shown. H‐NS K57N and H‐NS were produced using 1 mM IPTG.
