Abstract | The effect of static magnetic field (MF) on the growth and biochemical indices of five fungal genera were studied. Exposing the above genera to the northern pole, southern pole and both poles and their influences were compared with the control treatment (without MF energy). The static MF of 10 gauss was applied to the above fungal genera for seven days at 28°C. The effect of static MF energy on the growth of fungal genera on solid media Sabouraud Dextrose Agar (SDA) and Potato Dextrose Agar (PDA) was classified as stimulatory, inhibitory and no observable effect on growth of fungal genera. The effects of MF poles (southern, northern and both) inhibited the growth of Fusarium oxysporum, while the MF poles stimulated the growth of fungal genera (Aspergillus niger, Alternaria alternate and Penicillium chrysogenium) and had no observable effect of southern pole and both poles on growth of Rhizopus oryzae, while the northern pole inhibited the growth of R. oryzae compared with control group by measuring the growth diameter (cm). The effects of MF poles on the biochemical indices of the fungal genera were performed by filtering the growth and measuring the enzyme activity in the filterate. Exposing the fungal genera to the northern pole, southern pole. The fungal genera were influenced by MF energy for 3 days at 28°C and pH6.5 showed increased in the activities of amylase and protease due to northern pole at significant difference (at the 0.05 levels), the northern pole increased amylase activity (U/ml) in the culture medium filteratedof P. chrysogenumup to (0.246 U/ml) higher than other mentioned genera, A. niger, F. oxysporum, R. oryzae and A. alternata 0.172, 0.146, 0.116, 0.105U/ml respectively. The northern pole increased protease activity (U/ml) in the culture filterate of P. chrysogenumup to (0.081 U/ml) higher than other mentioned genera, A. niger, A. alternata , R. oryzae and F. oxysporum 0.08, 0.074, 0.056,0.054U/ml respectively and decreased when treated with southern pole however it was higher than the control treatment under optimum condition. |
