It was f und that w ith in a certain range, the killing rate increased w ith rising aerati n rate, initial p pu lati n f the bacteria, durati n f incubati n, pH and tem perature. W hen the aerati n ratew as set at 500 mL - 1 6 - 1 m in , in itial p pulati n f the bacteria at 9 10 mL , pH at 918, temperature at 317 K, durati n f incubati n at 4 days, and durati n f treatm ent at 10 m inutes, the killing rate f M icrocys tis aerug inosa reached as h igh as cl se t 1000% .
