What can be done with ordinary mushrooms? Surely you can find not one recipe for a tasty to cook them. But as it turned out, in order to extract from mushroom of some benefit does not necessarily have a culinary talent. But if you are savvy in physics, biology, and know the properties of graphene, you are quite capable of turning the mushroom into a source of electricity generation.
According to the editors of Science Daily, responsible for the development of a team of Stevens Institute of Technology (USA). Science has long known the special kind of bacteria called cyanobacteria. They themselves without any auxiliary tools can produce electricity. Their use for these purposes seems logical, there is only one “but”: cyanobacteria are very poorly acclimatized on artificial nutrient media. Identifying the most appropriate locations for habitat of bacteria, scientists have found that they are very well they survive in the mushroom caps of the mushrooms. And hats living fungi they live several times longer.
But the experts did not stop and created the first of its kind “hybrid bionic mushroom”: using a 3D printer to the surface of the cap caused a network of graphene conductive ink, which top was covered with clusters with the content of cyanobacteria. And 2 of these printed layer thus to have multiple points of intersection for signal transmission.
“By combining cyanobacteria, which can produce electricity with nanoscale materials, the ability to collect current, we were able to access their unique properties and those and others. We have created a brand new functional bionic system.” — said one of the authors Manu Manner.
Printed an extensive network of graphene is used to collect electricity, while cyanobacteria develop it. Well, the pileus acts as a substrate for the nutrition of bacteria. Generation of electric current starts when exposed to light.
“We showed that it is possible to create a symbiosis between two different microbial kingdoms.”
In addition, experts note that the quantity of electricity that is produced bacteria that depends on how tightly they are Packed into clusters. Accordingly, the denser “stacking”, the greater the amount of energy happens in the end.
