B13C:
Microbial Growth on Iron: You Cannot Spell Life without Fe Posters


Session ID#: 8451

Session Description:
Iron is the most abundant element and as such represents a huge energy reservoir for microbial growth. Iron-oxidizing microbes alter the biogeochemistry of their environment and create iron-oxide structures that can be found in the fossil record. In this session we will explore the expanding field of microbial-mediated iron-oxidation from both culture independent and culture dependent perspectives. Recent advances in culturing techniques have expanded the availability of isolates for physiological experiments and genome sequencing. Genome-sequencing projects have revealed enzymes conserved across phylogenies that are potentially involved in iron oxidation. In addition, to isolate genomes, metagenomic and single cell genome projects have added to the known metabolic capabilities and biodiversity of iron-oxidizers. These data have shown that iron-oxidizers fix carbon in a habitat specific manner, which further alters the local biogeochemistry. We invite contributions from field and laboratory studies exploring the physiology and genomics of iron-oxidizing microbes.
