Fig 1.
The results of two different methods to enumerate intact Escherichia coli’s concentration.
SYPI stained cells were enumerated by flow cytometry for intact cell counts. The unit of FCM’s results is cells.mL-1 and the unit of HPC’s results is CFU.mL-1. All data points are average values for triplicate samples. Error bars indicate standard deviations. Group 1–3 were three groups of random Escherichia coli suspensions.
Fig 2.
The variation tendency of intact bacteria concentration in 72h.
All data points are average values for triplicate samples. Error bars indicate standard deviations. (CK means the initial free chlorine concentrations were 0 mg.L-1. The line with circles means the initial free chlorine concentrations were 0.3 mg.L-1 and the line with triangles means the initial free chlorine concentrations were 0.6 mg.L-1).
Fig 3.
The variation tendency of AOC concentration in 72h.
All data points are average values for triplicate samples. Error bars indicate standard deviations. (CK means the initial free chlorine concentrations were 0 mg.L-1. The line with circles means the initial free chlorine concentrations were 0.3 mg.L-1 and the line with triangles means the initial free chlorine concentrations were 0.6 mg.L-1).
