Design of Low-Cost Ethanol Production Medium from Syngas: An Optimization of Trace Metals for <i>Clostridium ljungdahlii</i>

Syngas fermentation via the Wood-Ljungdahl (WL) pathway is a promising approach for converting gaseous pollutants (CO and CO<sub>2</sub>) into high-value commodities. Because the WL involves several enzymes with trace metal components, it requires an adequate supply of micronutrients in...
