It is not born in the form of coins, but in small gold nuggets. If you see a red spruce, look twice-look for shiny details.
Jose Saramago said: if you can look, see, if you can see, notice. A team of scientists has just discovered tiny gold-red gold particles (Picea Abies).
All thanks to symbiotic microorganisms that alter the chemistry inside the leaves and needles.
“Our results suggest that bacteria and other microorganisms that live within plants can influence the accumulation of gold in trees,” explains researcher Kaisa Lehosmaa of the University of Oulu, Finland, Ao.
in the new, published in Environmental Microbiome, Scientists got connect bacteria that live inside the needles of this type of tree to Formation of Gold Nanoparticles.
“Biogeochemical methods are already used in mineral prospecting, but this new investigation deepens our understanding of what really happens in the process,” explains the teacher Maarit Middletondo GTK.
The team Collected 138 needle samples of 23 redes-red and divided them into two types of analysis.
A group sought golden nanoparticles com Electronic Microscopy of Field Issuance Sdamper Combined with dispersive energy x -ray spectroscopy. And the result was surprising: in Four treeswere found golden nanoparticles inside the needles.
“Our study provides preliminary evidence of how gold moves through the stems of plants and how nanoparticles form within the needles”, Says Lehosmaa.“ In the ground, gold is in a liquid and soluble form. Transported by water, it reaches the spot needles, where the microbes rush it again in solid nanometric particles. ”
