Butanol production. Image 2 of 2. Chemical engineer adding enzymes into a bioreactor. This is being done to simultaneously hydrolyse wheat straw into simple sugars and produce butanol. Hydrolysis is a common technique that is used to break down certain polymers. Bioreactors are devices that maintain a specific environment to allow organisms or their derivative substances to undergo chemical processes. They allow all aspects of the environment, such as pH, temperature, and light, to be controlled and maintained at the required levels.
