Siderophores of Cunninghamella blakesleeana NCIM 687

The fungus Cunninghamella blakesleeana NCIM 687, industrially recognized for progesterone biotransformation, was found to produce two siderophores at low stress of iron (upto 40 μM iron in the growth medium). HPLC analysis and direct comparison with authentic samples characterized one of them as ferrichrysin (hydroxamate type) and other probably as a member of the coprogen family of siderophores.
