Scientists accidentally discovered a bacteria that eats metal

Microbiologists California Institute of technology discovered an unusual bacteria that feed on manganese, the existence of which was predicted over a century ago.

The study showed that bacteria use manganese to convert CO2 into biomass. This process is called chemosynthesis. Scientists had been aware of the existence of bacteria and fungi can oxidize manganese or to deprive it of electrons. On this basis, they suggested that there may be unknown microbes using this process for their growth.

One of the participants of research, Professor Jared Leadbetter found chemosynthetic bacteria on a glass jar, which he forgot to wash before leaving, after which she lay for several months until his return.

The attention of Ledbetter attracted an unusual black patina on the pot, which proved to be oxide of manganese, produced by unidentified bacteria, which, apparently, came to the surface with tap water.

Manganese is one of the most spread chemical elements. Oxides of manganese (MnO2) represent the dark lumpy substance that is found in soil sediments and in water distribution systems.

The research results will help to understand the formation of a special manganese formations of nodules which cover a significant portion of the seabed. These spherical formations, sometimes reaching the size of a grapefruit was first described in the 70-ies of the XIX century. In recent years, mining companies are developing plans of their prey, since they may contain rare metals.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
