Abstract:

Siderophores production in vitro was declined with increasing iron concentration in culture media and varied according to fungal strains and irradiation. Irradiated Aspergillus niger strain was superior over irradiated Penicillium oxalicum strain in siderophores production. The highest value of siderophores produced by A. niger, and P. oxalicum, respectively was achieved at pH 5.5 and pH 4.5 value. This holds true with both fungal strains either irradiated or not. Despite of fungal strains, the overall means of culture media reflected the superiority of Sabouraud agar (SA) culture medium on producing siderophores. The maximum siderophores production (73.31) was achieved at 25ºC for both tested fungi. Irradiated or non-irradiated strains of A. niger, and P. oxalicum resulted in the highest siderophores with sucrose as a carbon source and sodium nitrate as nitrogen source. Generally, the two irradiated strains surpass the non-irradiated ones and no significant difference between A. niger and P. oxalicum strains either irradiated or not.
