Effects of gentian violet and boric acid on growth of the fungi : Aspergillus flavus, Penicillium chrysogenum and P. expansum

الملخص EN

The maximum Percentage inhibition of growth of Aspergillus flavus (which can cause a wide spectrum of diseases ranging from allergic to a life-threatening invasive disease Aspergillosis).

P.

chrysogenum and P.

expansum whose mycotoxins can cause significant health risks ranging from the infections of fruits, vegetables and milk products to immune compromised individuals), by an organic dye (Gentian Violet) were 78.8, 77.7 and 76.6 % respectively.

While that of inorganic boric acid of (2 %) maximum concentrations inhibition were (44.4, 52.2 and 61.1 %) respectively.

This results was attributed to the amphiphilic properties of this dye i.e.

its high solubility in both aqueous (hyrophilic) and organic (lipophilic) phases and became effective at site in the body (the cell membrane) and it must also be able to reach that sites.
