While there continue to be high hopes that biofuels made from plant products like corncobs and switchgrass can help meet our growing energy needs, one major obstacle has been the cost of enzymes which are used to break down these tough plant parts into simple sugars that can be turned into ethanol. But now, according to Environment and Energy Publishing, two of the world’s largest enzyme producers have come up with a way to produce enzymes at a cost of 50 cents per gallon of fuel — an astounding 80% drop from just two years ago. It will take the construction of large-scale factories to make this widespread, but with new enzymes allowing biofuels to be produced at under $2 per gallon, this maybe a development worth revving the engines over.
