Genome mining to unravel potential metabolic pathways linked to gallium bioleaching ability of bacterial mine isolates

Frontiers in Microbiology, 2022
Gallium (Ga) is considered a high-tech Critical Metal, used in the manufacture of several microelectronic components containing either gallium arsenide (GaAs) or gallium nitride (GaN). The current high demand for this critical metal urges the development

Sulfide mineral dissolution microbes: Community structure and function in industrial bioleaching heaps

Green Energy & Environment, 2019
Heap bioleaching is one of the most clean and economical processes for recovery of low-grade and complex ores, because the sulfide minerals are natural habitats for acidophiles capable of iron- and sulfur-oxidation.
