Efficient Gold Recovery by Microbial Electrochemical Technologies
The applicability of microbial electrochemical technologies for the recovery of gold was investigated. Two-chamber microbial fuel cells (MFC) with bioanodes buried in sediment were used in two operating modes. The cathodes (gold foil or graphitized paper), submerged in HAuCl4, solutions, were short-circuited with the bioanodes, and thus for the first ...

Scalability of Microbial Electrochemical Technologies: Applications and Challenges
Bioresource Technology, 2022During wastewater treatment, microbial electrochemical technologies (METs) are a promising means for in situ energy harvesting and resource recovery. The primary constraint for such systems is scaling them up from the laboratory to practical applications. Currently, most research (∼90%) has been limited to benchtop models because of bioelectrochemical,
