Inactivation of Bacillus subtilis var. niger of both spore and vegetative forms by means of corona discharges applied in water

► Generation of streamer in water can be done with generators delivering 60-90 kV. ► Reduction of Bacillus subtilis var. niger vegetative forms enable with corona discharges. ► The streamers induce H2O2 production and enable bacterial abatement. ► Streamers can induce spore reduction with the generation of shock waves.
