ABSTRACT
Thirtyfive siderophore producing fungi were categorized for their hydroxamate, catecholate or carboxylate nature by chemical and bioassays. Out of 35 fungi, 30 were hydroxamates and 5 showed carboxylate nature. However, none of the fungi produced catecholate type of siderophores. Eighteen out of 29 fungi were trihydroxamate and the rest 11 fungi were dihydroxamates. Twenty-three fungi were hexadentate and 6 were tetradentate in nature. Quantification of siderophores using standard compounds deferrioxamine mesylate and rhizoferrin revealed that Phanerochaete chrysosporium produced maximum among the hydroxamate producing fungi and Mycotypha africana resulted maximum among the carboxylate producing fungi.
