Caption: Bio-ethanol production research. Chemists researching the effects of pretreatment processes on the production of ethanol from wheat straw. Here they are collecting a sample of a fungal culture to determine whether fermentation inhibitors are present after pretreatment. Inhibitors can stop or reduce the rate of ethanol fermentation. Photographed at the National Center for Agricultural Utilization Research (NCAUR) Peoria, Illinois, USA.
