purifiedsiderophoresReady biodegradability tests of the isolated Siderophores wereexecuted following the respective OECD [67] guidelines. These testswere performed in batch reactors inoculated with microbial cul-tures taken from a domestic and industrial wastewater treatmentplants. The objective was done to evaluate the capacity of differ-ent microbial populations to degrade the produced siderophoresand analyses of the test substance with high performance liquidchromatograph
