Looking at the occurrence of conjugal transfer concerning the germs, two sorts of germs with diverse chlorine resistances had been exposed to NaClO under the very same problems, separately, and then combined so as to show the plasmid transformation induced by NaClO publicity. Briefly, water samples with 109 cfu/mL of E. coli, S. aberdeen and P. aeruginosa (carrier of RP4, donors) ended up treated with 6 mg/L NaClO for 20 min to kill most cells (Supplementary Desk S2) and after that neutralised by 0.1 mol/L of sodium thiosulfate and filtered (0.
