Genomes of biofuel yeasts reveal clues that could boost fuel ethanol production worldwide
Date:11/8/2009

November 6, 2009 As global temperatures and energy costs continue to soar, renewable sources of energy will be key to a sustainable future. An attractive replacement for gasoline is biofuel, and in two studies published online in Genome Research (www.genome.org), scientists have analyzed the genome structures of bioethanol-producing microorganisms, uncovering genetic clues that will be critical in developing new technologies needed to implement production on a global scale.

Bioethanol is produced from the fermentation of plant material, such as sugar cane and corn, by the yeast Saccharomyces cerevisae, just as in the production of alcoholic beverages. However, yeast strains thriving in the harsh conditions of industrial fuel ethanol production are much more hardy than their beer brewing counterparts, and surprisingly little is known about how these yeast adapted to the industrial environment. If researchers can identify the genetic changes that underlie this adaptation, new yeast strains could be engineered to help shift bioethanol production into high gear across the globe.

Two studies published in Genome Research have taken a major step toward this goal, identifying genomic properties of industrial fuel yeasts that likely gave rise to more robust strains. In one of the studies, researcher Lucas Argueso and colleagues from Duke University and Brazil have sequenced and analyzed the structure of the entire genome of strain PE-2, a prominent industrial strain in Brazil. The group's work revealed that portions of the genome are plastic compared to other yeast strains, specifically the peripheral regions of chromosomes, where they observed a number of sequence rearrangements.

Interestingly, these chromosomal rearrangements in PE-2 amplified genes involved in stress tolerance, which likely contributed to the adaptation of this strain to the industrial environment. As PE-2 is
