Description
Alternatives to fossil fuels are necessary to combat the rising concerns of the harmful effects of fossil fuel emissions on the environment and to accommodate current energy supply demands. The pressure to find an alternative fuel source that is both cost effective and environmentally friendly has increased in recent years. One alternative is bioethanol, a type of biofuel, which can be produced using yeast, specifically Saccharomyces cerevisiae, to break down many different substrates. Currently, bioethanol is fermented from sugar cane or cornstarch by releasing sugars, but this poses a problem. In the United States, the amount of cornstarch needed to produce enough bioethanol to meet market demand is more than the economy can afford to take from other industries that rely on the use of corn. Corn is used in too many different ways to take a vast majority of it to use solely for the purpose of bioethanol production. Therefore, researchers have been trying to develop new ways to ferment bioethanol from yeast. However, the replacement substrates, such as biomass waste, produce multiple growth inhibitors during the fermentation process that prevents the yeast from producing bioethanol.
