How do microorganisms interact with minerals, and how can this be harnessed for eco-friendly extraction? A project from Cornell University could bring answers.
The processing of critical resources like rare earth elements is complex and requires the use of a wide range of chemicals, which, if improperly handled, can cause significant environmental damage. International research is underway to address this and develop alternative methods. One challenge is that many approaches are not scalable to an economic level. This also applies to the extraction of minerals from ores and their subsequent concentration using microbes, a process known as biomining. Led by Cornell University in New York, an international team of scientists aims to change this. The team plans to create a “Microbe-Mineral Atlas,” which will include specific genes and catalog their interaction with minerals.
This could help create genetically engineered microorganisms for practical applications. The team will also explore whether and how regulatory guidelines must be adapted to accommodate this new form of biotechnology. Additionally, collaboration with secondary schools will aim to ease concerns among future employees in the sector regarding genetic technologies.
The creation of the atlas is supported by a $2 million grant from the National Science Foundation. In the past, the U.S. Department of Energy has also shown interest in the research of lead scientist Buz Barstow and provided funding.
