From compost to sustainable fuels: Heat-loving fungi sequenced
Date:10/3/2011

Montreal, October 3, 2011 Two heat-loving fungi, often found in composts that self-ignite without flame or spark, could soon have new vocations. The complete genetic makeup of Myceliophthora thermophila and Thielavia terrestris has been decoded by an international group of scientists.

The findings, published in Nature Biotechnology, may lead to the faster and greener development of biomass-based fuels, chemicals and other industrial materials.

"Organisms that thrive at high temperatures are rare. Fewer than 40 heat-loving fungi have been identified and they hold great promise in the production of many chemicals and biomass-based fuels," says senior author Adrian Tsang, a biology professor at Concordia University and director of its Centre for Structural and Functional Genomics. "We have cracked the genetic blueprint of two such fungi. To our knowledge these are the only organisms, aside from a few bacteria, whose genomes have been fully sequenced from end-to end."

In sequencing Myceliophthora thermophila and Thielavia terrestris, the research team also discovered that both fungi could accelerate the breakdown of fibrous materials from plants at temperatures ranging from 40 to 70 degrees Celsius. This temperature range is too hot for many of the typical enzymes, which form an important component of some industrial processes used to degrade biomass into a range of chemicals and products.

But where others fail, these fungi thrive. "Our next goal is to figure out how these organisms flourish at high temperatures and what makes them so efficient in breaking down plant materials," says Tsang.

These discoveries will further stimulate the search for better ways to transform green waste stalks, twigs, agricultural straws and leaves into renewable chemicals and fuels. Enzymes produced by these fungi could also be tweaked to replace the use of environmentally harmful chemicals in the manufacture of plant-based commodities such as pulp and paper.

Having a multi-sectorial research team, composed of scientists from academia, government and industry, is essential to making these new advances.

"We could not have made these findings separately, since this type of research benefits tremendously from the intellectual input of researchers from different sectors," Tsang says. "This is an important discovery as we position ourselves from a fossil-fuel economy to one that uses biomass materials."
