But in the absence of oxygen, Shewanella uses (oxy)hydroxide minerals. These metal particles may also have adsorbed heavy metals on them. As a result, Shewanella influence the mobility and bioavailability of iron and environmental contaminants like lead, cobalt, and arsenic.In CopyrightCollege of SciencePress releaseVirginia Tech.
