Biofuels like ethanol could help us reduce our dependence on fossil fuels , but growing crop for ethanol demand using up immense swaths of worthful ploughland . Now we might have a solution – thanks to some re - engineered yeast .
ethyl alcohol and other biofuels confront a bit of hurdles in becoming a viable alternative energy source , and one major trouble is that we can only synthesize them from nutrient crops and otherwise utilitarian agricultural resource . The end is to make fermentation alcohol using only non - edible plant , which are fuck as cellulosic materials .
The trouble is that the barm we habituate to transmute corn whisky cabbage into fermentation alcohol does n’t really work with cellulose - found simoleons , gain any such conversion a hideously ineffective cognitive process . But Jonathan Galazka and his team of investigator at UC Berkeley might have figured out a way around this . They found a fungus , N. crassa , that does grow well on cellulosic sugars , and then they isolated the enzymes it uses to glean the cellulose sugar .
Once they had identified the mechanism that enthrall and change over cabbage from the cellulose to the fungus , they removed this system of rules and adjust it to the biochemistry of the yeast S. cerevisiae , the barm most commonly used in the biofuels industriousness . The engineered yeast worked utterly , successfully growing on the cellulosic sugars and unfold up the possibility of harvesting large - scale ethanol supplies from these cellulose - based materials .
