Solar Powered Microbes Manufacture Biofuels

esocid alerts us to news that scientists from the University of Texas at Austin have created a microbe capable of making cellulose, which can then be turned into ethanol. The bacteria use sunlight as an energy source, and the cellulose can be harvested without destroying them. Quoting: "The new cyanobacteria produce a relatively pure, gel-like form of cellulose that can be broken down easily into glucose. 'The problem with cellulose harvested from plants is that it's difficult to break down because it's highly crystalline and mixed with lignins [for structure] and other compounds,' Nobles says. He was surprised to discover that the cyanobacteria also secrete large amounts of glucose or sucrose, sugars that can be directly harvested from the organisms."

    Err neither of you appear to have read the article.


    The figure quoted in the gp is for traditional 'corn' based biofuels. There's a prediction that this process could reduce it to 3.5% of this area that's 28700 Square miles (about the size of South Carolina).


    The other fact that's quite interesting in the article is that these bacteria are happy in salt water conditions.... Can you think of any large expanses of salt water around the place?

    From YFP (your frickin' post):
    "So ...
    - Maybe it was bred. Perhaps using something sexy like DNA splicing.
    - More likely it was newly discovered.
    - Most likely, it was identified from one of the nigh endless lists of prior discoveries of beasties that might do something useful, and refined by breeding.

    OK, so not created."

    From TFA:
    "Nobles made the new cyanobacteria (also known as blue-green algae) by giving them a set of cellulose-making genes from a non-photosynthetic "vinegar" bacterium, Acetobacter xylinum, well known as a prolific cellulose producer."
