Raw materials and enzyme technology Using the versatility of bacteria, new methods of making many industrially important chemicals will be introduced Alcohols, ketones, organic acids, sugars and polymers could all be made. Enzymes from bacteria will be used in chemical conversions, such as methane to ethylene oxide. Enzyme-controlled processes have the enormous advan tage of achieving at normal temperatures and pressures what often requires very high temperatures and pressures, with attendant high costs and danger, in conventional chemical plants.
