Biodiesel Production Fungal enzymes to degrade wood

 Trametes versicolor: white rot fungi can degrade lignin
So far, biofuels are produced from plants that serve as food or animal feed actually. But researchers want to develop wood and straw as a fuel supplier. May help fungi decompose in the natural wood - and for millions of years.


About 300 million years, the growth of coal ended rather abruptly. Researchers suspect that white-rot fungi were responsible. They had developed an enzyme that cleaves the education necessary for coal plant material lignin. Now, researchers want to use the power of fungi for the production of biofuels, as they report in the journal "Science". Because lignin is an obstacle here.
The international team of researchers had compared the genomes of various white rot fungi with that of brown rot fungi. The latter can not cleave lignin. The genetic difference suggests that the white-rot fungi 290 million years ago developed the lignin-cleaving enzyme, and also formed a separate genus. At the same time also ended the Carboniferous, the Coal Age, by the coal was still promoted.
The researchers see a direct connection. This is from plant material by means of pressure and the absence of oxygen coal, it may not rot before. Before that it protects lignin, the wood can be indigestible for many fungi. With the advent of lignin rotting mushrooms, this protection was no longer available.

E10: Controversial Fuel from the field

While biodiesel has to be imported to Austria, bioethanol E10 and for
this country can be produced sufficiently.
Already been fossil fuel in Austria biological components were mixed.
Diesel will be added around seven percent biodiesel (eg rapeseed),
gasoline about five percent ethanol (alcohol) made ​​from corn, wheat
or sugar beet.
While biodiesel has to be imported to Austria, bioethanol E10 and
for this country can be produced sufficiently. Due to the high
commodity prices, ethanol producers but are also Agrana imported wheat
and corn from Eastern Europe.
According to Ministry of Agriculture to bio-fuel production
currently 85,000 hectares of arable land are used, however, would be
180,000 tonnes resulting protein feed as a byproduct and thus replace

Arctic oil rush in the Treasury under ice

Oil firms push into the Arctic, since experts believe huge amounts of oil and gas under the Arctic Ocean. The Russian state company Rosneft and the U.S. oil company Exxon Mobil now want to establish in the Kara Sea oil rigs. But environmentalists warn: no one knows how to fight an oil spill could be under a sheet of ice.


For oil companies, the Arctic is a treasure trove. Unimaginable quantities of oil and gas lie under the Arctic Ocean, experts suggest - to exploit them fires the imagination of politicians and business leaders. More than a fifth of undiscovered reserves of raw materials of the earth to the researchers at the U.S. Geological Survey (USGS), according to lie in the region around the North Pole.
