Microwave treatment of Pasteuria penetrans parasite preparation for selective elimination of undesired microorganisms

R. K. Walia, T. E. Hewlett, D. W. Dickson


A Pasteuria penetrans spore laden parasite preparation, raised from peanut pod hulls in a field naturally infested with the bacterium and Meloidogyne arena ria (race 1), was exposed to microwave (MW) radiation to eliminate undesired microorganisms. MW radiation was given at medium, medium high or high levels for 1 or 2 min. Treatment of the parasite preparation at high radiation level for 2 min completely eliminated the undesirable fungal propagules, without significantly impeding the viability of P. penetrans endospores.
