Growth of the three pathogens, E. coli O157 (white
squares), V. cholerae (black circles), and P. aeruginosa (gray triangles),
in river water exposed to ozone. The growth potential, i.e., net grown
cells (A), as well as the fraction of estimated consumed assimilable
organic carbon (AOC) for each pathogen (B) are shown. RW, untreated
(raw) river water; ct 1 to ct 10, degree of oxidation (mg min/
liter). Error bars indicate the standard deviations for three replicate
samples.
