Isolation of Imaqobactin, an Amphiphilic Siderophore from the Arctic Marine Bacterium Variovorax Species RKJM285.

The amphiphilic siderophore imaqobactin was isolated from the Arctic bacterium Variovorax sp. RKJM285, a strain isolated from marine sediment collected from an inlet near Clyde River, Nunavut, Canada. The 2D structure of imaqobactin was determined by a combination of LC-HRMS, MS/MS, and NMR spectroscopic methods.
