Bioethanol can be obtained from a variety of biodegradable raw materials, and one of the cheaper raw materials is cornmeals (Zea mays). The most important, and at the same time the longest operations during the production of bioethanol from corn grits are enzymatic hydrolysis and fermentation, and the duration of these operations can be influenced by the application of various pretreatments. The aim of this study was to investigate the effect of photocatalytic pretreatment of corn grits, with or without the addition of TiO2, on the fermentation of bioethanol, using SHF and SSF fermentation procedures. Fermentation was monitored 7 days and better results were obtained with SHF process, and the addition of TiO2 had a positive effect in both SSF and SHF procedures (for samples treated for 180 and 240 minutes).
