Study the effect of Microwaves radiation in the growth of Some isolates fungi

Abstract

       Explained this study  the effect of microwaves radiation  with a frequency waves (a 2,450 MHz) on five fungal isolates (Aspergillus flavus, Aspergillus niger, Aspergillus fumigates, Penicillium chrysogenum, and alternaria alternate)  .Fungal isolates  that cultivated  on the   Sabouraud dextrose agar (SDA ) ,  at a rate of  three frequency for each isolate fungi  were exposed to the radiation of microwave oven with four time periods (0 second( control), 5 , 10 , 15 seconds). where the results showed  highly growth of colonies of each fungal isolates used in the study  that exposed to microwaves   of time periods (5 seconds, 10 seconds). While  killed all fungal colonies exposed to microwaves   for the time period (15 seconds). This study proved the ability of the waves and microwaves period of time (15 seconds) and above to kill the fungal colonies and do not allow for the growth of fungal spores, meaning that the rate of growth of fungal colonies is  inversely proportional to the length of time of exposure to radiation of  microwaves
