A treasure hunt for microbes in Chile's Atacama desert. The famously dry region has long been dismissed as a mostly lifeless wasteland, good for little more than mining of minerals and precious metals. To these researchers, however, it's a microbial gold mine worthy of protection. By Lindzi Wessel 08.26.2022.

Ancestral Minerals is a blend of Ancient Sea Salt, Atlantic Kelp, and Wildflower Bee Pollen, each a whole food source of essential minerals we need to thrive. Our ancestors have always relied on salt-preserved foods, fresh organ meats, beehive products, and marine life, including seaweed for both food and medicine.

What triggered the event and pulled the planet out of its low-oxygen funk is one of the great mysteries of science. A new hypothesis, proposed by MIT scientists, suggests that oxygen finally started accumulating in the atmosphere thanks to interactions between certain marine microbes and minerals in ocean sediments.

Bioleaching involves the use of microorganisms to catalyze the oxidation of iron sulfides to create ferric sulfate and sulfuric acid. Ferric sulfate, which is a powerful oxidizing agent, then oxidizes the copper sulfide minerals and the copper contained is then leached by the sulfuric acid formed. In the case of uranium, the ferric sulfate ...

Minerals also may be altered passively by the products of microbial metabolism, such as production of acid. Microbes use minerals as sources and sinks of electrons for coupled oxidation-reduction reactions, and many of these reactions enable the release and capture of energy from unstable or metastable minerals.

Shang and Rothman worked out a mathematical model that made the following prediction: If microbes possessed the ability to only partially oxidize organic matter, the partially-oxidized matter, or "POOM," would effectively become "sticky," and chemically bind to minerals in sediment in a way that would protect the material from further oxidation.

Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals. Valuable metals are commonly bound up in solid minerals.
