PHMG is effective against both aerobes and anaerobes. It kills 99.67%-100% of sulfate reducing bacteria, iron bacteria and saprophytic bacteria at a concentration of 7.5mg/L. Experiments show that MIC for sulfate reducing bacteria is not changed after 30 generations, indicating bacteria would not become resistant to PHMG after prolonged use.
