Technician Greg Kennedy (left) and chemist Badal Saha sample cellulosic ethanol from wheat straw produced in a 100-liter fermenter to assess its ethanol content and to monitor how quickly the sugars in the wheat straw are being fermented into ethanol. Using the 100-liter fermenter allows the scientists to scale up the process so that they can fine-tune it and identify technical problems that might develop during large-scale ethanol production.
