Effect of Magnetic Field Energy on Growth of Aspergillus flavus and Aflatoxins production

Abstract

The study was conducted to determine the impact of the magnetic field poles on aflatoxins produced by Aspergillus flavus. The subjected fungus to the northern pole, southern pole, both poles and their influences were compared with the control at which the fungus was not affected by magnetic field energy. Aspergillus flavus was influenced by magnetic field energy which applied through a magnet at different forces (5, 7,10,30,50 Gauss) for seven days at temperature of 27 o C. There are no different between the uses of magnate with 5 or 50 Gauss. The effect of magnetic field poles was observed on the growth of Aspergillus flavus on solid and liquid media. The southern pole had a positive effect on the growth of Aspergillus flavus by increasing the diameter of the colony or the turbidity of growth medium, while the northern pole had a negative influence on the growth of A. flavus, diameter or the turbidity, while the treatment of northern and southern poles together and the control treatment are equal. The most important conclusion that have been observed was the effect of magnetic field poles on the concentration of total aflatoxin produced by A. flavus, which was 454.73 ppb (when treated with southern pole) and 25.40 ppb (when treated with northern pole) while the control 212.46 ppb and both poles 88.33 ppb by using ELISA technique.

Effect of Static Magnetic Field on Monascus ruber M7 Based on Transcriptome Analysis

“…Recently, the MF effects, including SMF and low-frequency AMF (LF-AMF, <300 Hz) on filamentous fungi were studied. Ahmad et al found that the SN-pole (between the southern and northern poles) of SMF inhibited the concentration of total aflatoxin produced by Aspergillus flavus [ 21 ]. Mateescu et al discovered that 0.62 T SMF inhibits the growth of A. niger [ 22 ], while another study showed that LF-AMF increased the yield of citric acid and cellulase activity produced by A. niger [ 23 ].…”

Review on Desirable Microbial Phytases as a Poultry Feed Additive: Their Sources, Production, Enzymatic Evaluation, Market Size, and Regulation

“…R. oligosporus MTCC556 produced 31.3 U/gds of phytase from rice bran SSF, according to Suresh et al 2016 [ 62 ]. In comparison to wheat bran and oat bran SmF by Aspergillus flavus PHY168, Ahmed et al 2018 [ 47 ] reported the highest phytase production from 5% rice bran SmF by the strain. Furthermore, it was reported that Thermoascus aurantiacus SL16W produced more phytase from rice bran Sem-SSF than from wheat bran Sem-SSF [ 45 ].…”
