Biogenic Iron Oxide Sheaths
SEM – Landscape
Each iron oxidizing bacteria produces a unique morphology of biogenic iron oxides. What we see here is the “sheath” morphology (hollow tubes) produced by the bacteria Leptothrix. These iron oxides are found ubiquitously in the environment and have the ability to sequester organic carbon from their surroundings, possibly playing a significant role in carbon cycling and thus, climate change
