Tiny Red Crystals Dramatically Increase Biogas Production http://bit.ly/1XwZbuW
University of New South Wales (UNSW) Australia-led researchers have discovered a way to produce a tenfold increase in the amount of methane gas emitted by naturally occurring microbes living in coal seams and on food waste.
The innovation could benefit the environment by extending the lifespan of coal seam gas wells, as well as improving the economics of using woody crops and left-over food as commercial sources of biogas.
The technique involves the addition of small amounts of a synthetic dye that forms previously unobserved needle-like crystals to help the methane-producing microbes grow faster.
“It’s simple. If the microbes grow faster, they fart more methane,” says study senior author UNSW Associate Professor Mike Manefield.
