A well-known and widely used method for detection of siderophore production by microorganisms in solid medium is the universal chrome azurol S (CAS)-agar plate assay. However, the high toxicity of CAS-blue agar medium caused by the presence of a detergent impedes its utilization with many varieties of fungi and Gram-positive bacteria. To solve this problem, a modification of the CAS-agar plate assay was made by incorporating the CAS-blue dye in a medium with no contact with the microorganisms tested. Half of each plate used in our experiments was filled with the most appropriate culture medium for each type of microorganism and the other half with CAS-blue agar. This modification allowed us to study several strains of fungi (basidiomycetes, deuteromycetes, ascomycetes and zygomycetes) and bacteria (Gram positive and negative), some of them appearing for the first time in the literature. All the microorganisms grew properly and reacted in different manners to the CAS assay. Some strains of wood-decaying basidiomycetes (mainly white-rot fungi) and Aspergillus species produced the fastest color-change reactions in the CAS-blue agar. This modified method could facilitate optimization of culture conditions, since both CAS-blue agar and growth medium were prepared and added in the Petri plate separately.
