The inhibiting effect of microwave radiation on Paenibacillus larvae spores suspended in water

The aim of this paper was to investigate the effects microwave radiation on viability Paenibacillus larvae spores and study relationship between power consumption, exposure time number in examined suspensions. Sterile distilled water suspensions were made using larval detritus, contain tens, hundreds thousands spores. all dilutions gradually exposed a 170, 510 850 W. In cases, 1, 2, 3, 4, 5, 10, 15, 20, 25 30 minutes. After cooling, 0.1 ml each suspension inoculated onto three modified MYP (mannitol egg yolk polymyxin) agar plates incubated aerobically at 37 ± 1 °C for 120 hours. statistical evaluation spore counts decreasing with performed use nonparametric Friedman's variance test Unistat Statistical Package v6.5. results showed that rate devitalisation is dependent oven but independent Using consumption W, occurred after 3 2 min exposure, respectively.
