Evidence for the importance of catechol-type siderophores in the iron-limited growth of a cyanobacterium

摘要

To compensate for low levels of available iron, cyanobacteria may produce siderophores to assist in the scav- enging of iron from the environment. In this paper we examine the role of catechol-type siderophores produced by the halo- tolerant cyanobacterium Synechococcus sp. PPC 7002 in the acquisition of iron from a chelated source. To inhibit catechol- type siderophore mediated iron transport, bovine serum albu- min (BSA) was added to iron-deficient and replete cultures.
