Hungry fungus could unlock better biofuel production

Posted May 05, 2008 11:18 AM

From CBC | Technology & Science News:

A fungus responsible for the rapid deterioration of military clothing and canvas tents during the Second World War could significantly improve the production of biofuels, say U.S. scientists. Once the bane of soldiers fighting in the South Pacific, Tricoderma reesei is a hungry fungus that quickly digests plant fibres into simple sugars. In a paper published Monday in Nature Biotechnology, researchers at the Los Alamos National Laboratory and the U.S. Department of Energy Joint Genome Institute say the fungus's genetic sequence gives important clues about how it breaks down plant fibres. The finding could lead to processes that more efficiently and cost effectively convert corn, switchgrass and even cellulose-based municipal waste into ethanol. Ethanol from waste products can be a more carbon-neutral alternative to gasoline. However, there is an ongoing global debate over fuel and food production. Groups like the Sierra Club of Canada point out that while more ethanol and less gasoline makes sense, it has to be the right kind of ethanol. The environmental group says it takes five hectares of cornfields to produce enough ethanol to run a car for a year. The same land could feed seven people for a year. The Sierra Club of Canada has urged government to switch from relying on ethanol derived from corn and grains to ethanol produced from waste straw and wood chips. It argues that producing ethanol from those sources doesn't take farmland out of food production and achieves greater reductions in the emission of greenhouse gases.

If all the effort spent on these methods of making synthetic petrol and diesel had been placed into research on fuel cells and/or solar cells, so that electric wheel vehicles could be used in trains, buses, trucks and cars, we would be in a much better state than at present.

When will our so-called "Leaders" come to understand the oil age has been and gone forever.

Kind Regards....

Hey Sparks. They'll understand when we take their money and their toys away from them and send them to their rooms for being bad little politicians!

The politician,

And his sisters, and his cousins, and his aunts!
His sisters and his cousins,
Whom he reckons up by dozens,
And his aunts!


... all have theirs sticky fingers in the oil business.

(Apologies to Gilbert & Sullivan)

You get a good answer point for effort.

Several problems, Sparky. Where does all the electricity come from? We would have to have about twice as many electric generating plants as we do now. The alternative sources are not reliable enough and cost too much when compared to nuclear plants, coal-fired generating plants and hydropower. But we can't have nuclear because of radioactive waste, coal-fired plants because of CO2 and dams change the environment and cannot be allowed. If you think gasoline is expensive, try using nothing but the alternative power sources; wind, solar, geothermal, etc and see what energy costs then.

EVs have a niche where they can be used in certain ways, but they cannot yet replace the normal automobile because of lack of range, speed, convenience, size and especially in cost. A hybrid between an EV and a fueled vehicle would not unduly tax the electric grid and would use much less fuel for the miles traveled. My preference is the more efficient and less polluting steam-electric hybrid.

"Leaders"? They are politicians who serve every special interest group except the voters, because the voters are not organized. They bow to the money from business and kowtow to every environmentalist group who promises votes.

The "Oil Age" is just winding down slowly and those who have their lives and money invested in it will fight anything that threatens them. Sasol has been making synthetic fuel from coal for years and WW II Germany did the same.

Sparkstation, Please check out the research on HE3 fusion. It produces an equal amount of energy to H-H fusion, less than one tenth the radiation and the plasma can be contained by electro-static fields instead of nearly impossible to to maintain "magnetic bottles".

The other positive point of HE3 fusion is that it has successfully been done in a laboratory.

Cordially, Dragon

Sounds like something that could work. Which hysteric will worry about it getting loose and eating all our cloth?
