AB  - Lactic acid is a significant chemical for the food industry. Fermentative lactic acid production on wastes could significantly improve the economy and sustainability of the process. In this study, lactic acid production was performed by L. rhamnosus ATCC 7469 on a stillage from bioethanol production on waste bread. Under optimal conditions, in fed-batch fermentation lactic acid productivity of 1.80 g L-1 h-1 has been achieved with a cell number of above 109 CFU mL-1. L. rhamnosus has shown high survival rate of over 85% in the presence of beef bile and at low pH value of MRS broth. The residuals after the fermentation were chemically analyzed and their composition corresponded well with the values recommended for the feed. The digestible energy was 17452.25 kJ kg-1, while metabolisable energy was 17360.83 kJ kg-1. The high values of energy parameters indicated that an integrated process for lactic acid and feedstuff production could be a good strategy.
AB  - Mlečna kiselina je važna supstanca za prehrambenu industriju. Proizvodnja mlečne kiseline fermentacijom na otpadnim sirovinama može značajno da poveća ekonomičnost i održivost procesa. U ovom radu je ispitivana proizvodnja mlečne kiseline pomoću L. rhamnosus ATCC 7469 na džibri iz proizvodnje bioetanola na otpadnom hlebu. Pod optimalnim uslovima, u dolivnom postupku je postignuta produktivnost mlečne kiseline od 1.80 g L-1 h-1 sa više od 109 CFU mL-1 bakterija. L. rhamnosus je pokazao visok stepen preživljavanja od preko 85% u prisustvu žučnih soli i pri niskoj pH vrednosti MRS bujona. Ostatak nakon mlečno-kiselinske fermentacije džibre je hemijski analiziran i pokazano je da dobijene vrednosti odgovaraju preporučenim. Svarljiva energija je iznosila 17452,25 kJ kg-1, dok je metabolička energija bila 17360,83 kJ kg-1. Visoke vrednosti energetskih parametara hraniva ukazuju da integrisani proces proizvodnje mlečne kiseline i stočne hrane na džibri predstavlja povoljnu strategiju.

AB  - Bioethanol has become one of the most promising biofuels today in response to uncertain fuel supplies and efforts to
reduce greenhouse gas emissions. The biofuels are easily available from common biomass sources, biodegradable and
contribute to sustainability. In Serbia, the industrial production of bioethanol still relies on conventional energy crops
containing starch and sugar such as corn, wheat and triticale, which are the most suitable and available agricultural raw
materials. The preview of bioethanol production possibilities and available feedstocks in Serbia are presented in this study.
Several production approaches based on crop selection, process integration and waste utilization were also considered in
order to increase production efficiency and to avoid the competition of the feedstock utilization for food and energy.
Utilization of corn, wheat and triticale (plant resistant to severe climate and soil conditions) were investigated for
bioethanol production as well as utilization of damaged crops (e.g. wheat) that are not appropriate for food consumption.
Also, utilization of the stillage for the production of lactic acid could also improve the bioethanol production. The
economy of bioethanol production was analyzed in order to decrease the production costs and make this biofuel
competitive with fossil fuels. The analysis has compared the cost of bioethanol produced from three crops that can be
cultivated in Serbia: corn, wheat, and triticale, and the triticale has shown as the most favourable.

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.
