New paper in-press

Our new paper in the journal Environmental Microbiology reports the discovery of ‘Rhodopetrobactin’ siderophores from the nitrogen-fixing bacterium Rhodopseudomonas palustris. The chemistry of Rhodopetrobactins appears to be well suited for the versatile lifestyle of R. palustris which includes nitrogen-fixing phototrophic growth modes in sediment and soil with variable anaerobic and aerobic conditions.
