Iron reduction in soil
WebMar 19, 2024 · Dissimilatory iron reduction (DIR) is the process where enzyme-producing bacteria can reduce ferric to ferrous to obtain energy without assimilating the iron, which has attracted interest since the late 1980s (e.g., Myers and Nealson 1988; Lovley 1991; Weber et al. 2006 ). WebSep 6, 2012 · Iron reduction is particularly important for the mobility of contaminants in the environment. Because many contaminants, most notably uranium, bind to iron, the change also can affect the spread of these contaminants.
