In the plant world there are creatures capable of surprising even the most botanical experts, and among these a place of honor is up to the Rhinetea Niccoliferaa rare plant discovered in Philippineson the island of Luzon. This small shrub is able to perform a real biological enterprise: absorb large quantities of nickel from the ground without suffering damage.
To be precise, it can store up to 18,000 parts per million metal in its leavesa threshold a thousand times higher compared to that tolerable by most plant species. This ability is part of a phenomenon known as hyperaccumulusextremely rare in nature: it is estimated that only 0.5% of plants that grow in metalliferous soils is able to develop this adaptation. To date, about 450 hyperaccumulator species Over 300,000 vascular plants Notes, making the Niccolteria Rhineteen a truly exceptional specimen.
In addition to botanical curiosity, this plant has an extraordinary potential for the environmental remediation. Thanks to the process of phytodepurationcan be used for reclaim contaminated soils from heavy metals such as nickel, contributing to clean up degraded areas without having to resort to invasive interventions.
Phyomining
But that’s not all: the Niccolteria Rhineteen could also become the protagonist in the field of Green mininga new frontier of sustainable mineral extraction that provides for the use of plants for extract precious metals from the ground in an ecological way.
This approach, called phyomingis proposed as an alternative to traditional high environmental impact methods, offering a cleaner solution for Recovery of natural resources Like nickel, used in numerous industrial technologies.
The discovery, documented in the scientific magazine Phytokeysis the result of the work of an international team led by Professor Edwino Fernando of the University of Los Baños, with the contribution of Professor Agostino Doronila of the University of Melbourne. Together, these scholars show how much there nature may be a precious resource to face environmental challenges contemporary, suggesting a future in which plants not only embellish the planet, but they really care.
