Producing biofuel from food crops has been controversial, because it can raise the cost of corn and grain. Read more »
Using synthetic biology and enzyme engineering, a new form of E. coli bacteria was created that can digest all the sugars found in brown seaweed, producing ethanol that is twice the yield of sugar cane and five times that of corn. This breakthrough of transforming seaweed into fuel has been the dream Read more »
