Figure 7
Regrowth of sanitizer-treated bioluminescent Escherichia coli Xen14. Aliquots of all samples treated with electrolyzed oxidizing water (EOW) sodium hypochlorite (NaClO) or chlorine dioxide (ClO2) in Fig. 6 were added to fresh Luria Bertani broth and then incubated at 37 °C in a Cytation 5 Cell Imaging Multi-Mode Reader for another 40 h. Total luminescent signals (relative light units) were collected over a 40 h incubation period. 3°, tertiary treated effluent water; 2°, secondary treated effluent water. Figures were generated using Prism v8 (GraphPad Software, San Diego, CA, USA).
