Mascoma is a biotechnology company spun out of the University of Dartmouth to genetically design micro-organisms that can turn the cellulose in plants into ethanol.

The company is testing its system, which does not use enzymes as traditional ethanol processing does, in New York with plans for a plant in Michigan as well. For a visual tour of its lab, click here.
