AB  - Bioethanol produced by fermentation of biomass, such as sugar, starch, or lignocellulosic materials, is one of the most important renewable energy resources. An average thin stillage amount produced in the bioethanol process is approximately 13 hL per hL of bioethanol. An adequate utilization of the stillage is of great importance in order to improve the economy of the bioethanol production. The aim of this paper was to study the possibilities of stillage utilization from the process of bioethanol production from corn. For this purpose the recirculation of thin stillage in the amount of 10-30% in mashing process was studied, while the solid phase remained after filtration was assessed for animal feed. The results have shown that the ethanol yield in the process can be significantly increased by the recirculation. The dry matter content in the slurry after the fermentation also increased with the increasing amount of recirculated stillage. Chemical composition of solid stillage remained after fermentation as well as of the solid stillage enriched with yeast (1 %of dry Saccharomyces cerevisiae yeast) was studied. The stillage enriched with yeast had a greater amount of proteins and generally can be used as a high quality feed.
AB  - Bioetanol proizveden postupkom fermentacije biomase na bazi šećera, skroba ili lignoceluloze predstavlja jedan od najznačajnijih obnovljivih izvora energije. Prilikom proizvodnje 1 hL etanola nastaje oko 13 hl bistre džibre. Da bi se povećala ekonomičnost ovog postupka od izuzetne važnosti je da se džibra koja nastaje kao otpadni proizvod adekvatno valorizuje. Cilj ovog rada je da se ispitaju mogućnosti iskorišćavanja džibre nastale prilikom proizvodnje bioetanola na kukuruzu. U radu je ispitivana recirkulacije bistre džibre u količini od 10-30% u fazu ukomljavanja kukuruza za proizvodnju etanola, dok je zaostala čvrsta faza nakon filtracije razmatrana za korišćenje u ishrani stoke. Utvrđeno je da se recirkulacijom može značajno povećati koncentracija etanola u proizvodnom procesu. Sadržaj suve materije u džibri zaostaloj nakon fermentacije se takodje povećavao sa povećanjem količine recirkulisane bistre džibre. U radu je ispitan hemijski sastav čvrste džibre i džibre obogaćene kvascem (1 % suvog Saccharomyces cerevisiae kvasca) i analizirana nutritivna vrednost ovih uzoraka. Džibra obogaćena kvascem je imala značajno veći sadržaj proteina i generalno se može koristiti kao visoko kvalitetna hrana za životinje.

AB  - The interest in maize as an ethanol producing plant was caused by the energetic crisis and restored as early as the beginning of the 1970s. The production of bioethanol as a fuel has been expanding for the last ten years. Renew ability of maze as a raw material and growing environmental pollution by oil products represent two principal reasons for maize becoming one of the major raw materials for the energy production. According to the insight into the development of the research work on the improvement of maize utilization, the objective of the present study was set up. The objective was to observe grain quality and fitness of ZP maize hybrids of a different genetic background in order to use them in the bioethanol production. The results obtained on the chemical composition, physical and fermentable properties of grain of selected ZP maize hybrids were presented in this study.
AB  - Interesovanje za kukuruz kao etanol produkujuću biljku uzrokovano je energetskom krizom i obnovljeno je još početkom 1970-ih godina. Poslednjih desetak godina proizvodnja bioetanola za gorivo je u sve većoj ekspanziji. Obnovljivost kukuruza kao sirovine i sve veća zagađenost životne sredine produktima nafte predstavljaju dva osnovna razloga da on postaje jedna od glavnih sirovina za proizvodnju energije. Sagledavajući perspektivu razvoja istraživačkog rada na unapređenju korišćenja kukuruza za cilj ovog rada je postavljeno da se ispita kvalitet zrna i pogodnost ZP hibrida kukuruza različite genetičke osnove za proizvodnju bioetanola. U radu su prikazani rezultati ispitivanja hemijskog sastava, fizičkih i fermentacionih karakteristika zrna odabranih ZP hibrida kukuruza.
