Abstract
|
|
|
Plasma reactor was used for the inactivation of Phytophthora capsici which is phytophthora blight pathogen in
aquiculture. Effects of first voltage, second voltage, air flow rate, pH, incubation water concentration were examined. At
the low 1st voltage, under 80 V, the lag phase was noticed within 30 sec, however, it was not shown over 100 V. The
variation of optimum operation condition was not shown by the variation of microorganisms. However, the inactivation
rate was different by the variation of species of microorganisms. The inactivation rate and efficiency were increased by
the increase of 2nd voltage. The highest initial inactivation rate was shown at pH 3 and the rate was decreased by the
increase of pH. The inactivation rate increased by the increase of air flow rate, however, it was shown as similar at the
rate of 4 L/min and 5 L/min. The inactivation rate was distinctly decreased at the three times concentration of incubation
solution comparing at the distilled water and basic incubation solution.
