Abstract
Ohmic heating and pulse low electric field (PLEF) treatments were applied to cause a lethal effect onAlexandrium catenella cells suspended in seawater. The survival ofA. catenella treated with ohmic heating decreased with electric field strength and treatment time. The maximum of only 10% reduction in survival was achieved with 1 s treatment at 50 V cm−1. On the other hand, the application of pulse low electric treatment of 70 V cm−1 field strength for 3 × 10 ms resulted in high destruction levels of A. catenella cells (survival 0.01%), thus is an effective method for inactivation of toxic dinoflagellates in ballast water.
