The role that neutrophilic iron-oxidizing bacteria play in the Arctic tundra is unidentified. chloroplasts accounted for 3 to 25% of the communities. Oxygen profiles showed evidence for oxygenic photosynthesis at the surface of some mats, indicating the coexistence of photosynthetic and FeOB populations. The relative abundance of OTUs belonging to putative Fe-reducing bacteria (FeRB) averaged… Continue reading The role that neutrophilic iron-oxidizing bacteria play in the Arctic tundra
