Potassium permanganate (KMnO4) was investigated for its ability to inactivate cultures of agar-grown Legionella pneumophila in a phosphate buffer (pH 6.0 and pH 8.0) at 7°C At pH 6.0, significantly higher inactivation rates, k values, (0.300 log10 reduction min-1 of L. pneumophila were observed compared to those at pH 8.0 (0.032 log10 reduction min-1). By exposure to 5.0 mg L-1 KMnO4 more than 99% (2 log10 cfu mL-1) reduction in the bacterial numbers was achieved within 10 minutes at pH 6.0; however, at pH 8.0, at least 60 min was required for 99% reduction. KMnO4 was significantly more effective at 5.0 mg L-1 compared to 2.5 and 1.0 mg L-1. Water systems with KMnO4 may gain disinfection credits as proposed by the U.S. Environmental Protection Agency. |
