AB  - Stillage is a main by-product of the bioethanol industry and, depending on the
origin of substrates for bioethanol production, it can be a significant pollutant
affecting the profitability of bioethanol production. Directing the stillage towards
the production of bio-based chemicals or high-quality feed is a preferred stra-
tegy. In this paper, a complete utilization of stillages of different origins was
assessed. Thin stillages from bioethanol production from molasses, wasted
bread and corn were chemically characterized, evaluated and compared as
substrates for lactic acid (LA) and probiotic biomass production by Lactobacil-
lus rhamnosus ATCC 7469, while solid fractions of wasted bread and corn stil-
lages were analyzed for feed. The impact of pH control using CaCO 3 or NaOH
was also examined, both in terms of LA production and valorization of the
remains generated in each process.A maximal LA productivity of 1.14 g/(L h)
was obtained on thin wasted bread stillage with pH control by NaOH while the
number of viable probiotic bacterial cells was above 109 CFU/mL. The com-
position of the solid fraction of the wasted bread stillage was complementary
with the needs of monogastric animals, while the solid fraction of corn stillage
was more adequate for the nutritional requirements of ruminants.

AB  - Maize (Zea mays L.) is one of the most important cereal crops. and one of the most significant renewable raw materials for the production of energy and many different products. Bioethanol is a biofuel that is mostly used as a replacement for fossil fuels worldwide. Major by­product that arises from the fermentation process of corn is dried distillers' grains (DDG). Due to its high feeding value it represents an excellent component for livestock feed mixtures. The main goal of this study was to determine the technological quality of maize grain and the influence of maize hybrid on bioethanol yield and quality of this process' by-product, dried distillers' grains. Five maize hybrids developed at the Maize Research Institute, Zemun Polje, were investigated in this study. The lowest concentration of bioethanol in the fermentation medium after 44h of alcoholic fermentation (8.64% w/w) was obtained by hybrid ZP 560, and the highest (9.10% w/w) by hybrid ZP 600, while compared to the maximum theoretical bioethanol yield, the highest scoring hybrid was ZP 606 (93.59%) and the lowest ZP 505 (87.33%). The highest in vitro dry matter digestibility of DDG was determined in a sample obtained from hybrid ZP 505 (82.41%) and the lowest (77.12%) in the DDG sample of ZP 606. The chemical composition and physical characteristics of the grain, as well as other parameters of the production process have influenced the overall bioethanol yield. Hybrids created in the Maize Research Institute represent unique starting material for research of the possibilities of bioethanol, starch, food and animal feed production.
AB  - Kukuruz (Zea mays L.) je jedna od najznačajnijih ratarskih biljaka koja se svrstava u veoma važne obnovljive ugljenohidratne sirovone za proizvodnju energije i mnogobrojnih proizvoda različite namene. Bioetanol je biogorivo koje se najviše koristi kao zamena za fosilna goriva. Trend proizvodnje ovog goriva je rastući, a kukuruz zahvaljujući visokom sadržaju skroba u zrnu, predstavlja jednu od najboljih obnovljivih sirovina za njegovu proizvodnju. Suva kukuruzna džibra je najznačajniji sporedni proizvod dobijanja bioetanola iz kukuruza. Zahvaljujući visokoj hranljivoj vrednosti, sadržaju proteina i drugih hranljivih materija, predstavlja kvalitetno hranivo koje može naći primenu kao komponenta u smešama za ishranu životinja. U cilju ispitivanja uticaja hibrida kukuruza na kvalitet zrna, fermentaciona svojstva, prinos bioetanola i kvalitet suve kukuruzne džibre korišćeno je zrno pet hibrida kukuruza stvorenih u Institutu za kukuruz 'Zemun Polje'. Najnižu koncentraciju bioetanola u fermentacionom medijumu nakon 44h alkoholnog vrenja (8,64 % w/w) ostvario je hibrid ZP 560 a najvišu ZP 600 (9,10 % w/w). U odnosu na maksimalni teorijski prinos najviši je imao hibrid ZP 606 (93,59%), a najniži ZP 505 (87,33%). Najveća in vitro svarljivost suve materije kukuruzne džibre određena je u uzorku dobijenom od hibrida ZP 505 (82,41%), a najniža (77,12%) u uzorku džibre hibrida ZP 606. Hemijski sastav i fizičke karakteristike zrna, kao i drugi parametri procesa proizvodnje uticali su na prinos bioetanola.

AB  - Utilization of distillery stillage from bioethanol production for lactic acid and feed production was studied. The lactic acid fermentation of the stillage was performed by Lactobacillus rhamnosus ATCC 7469 and maximal lactic acid concentration of 50.18 g L-1, yield of 0.90 g g(-1), productivity of 1.48 g L-1 h(-1) and viable cell number of 5 x 10(9) CPU mL(-1) were achieved. Solid residues with biomass remains after lactic acid fermentation were assessed for animal consumption. The content of proteins and ash decreased in the residues after the fermentation, whilst the content of oil and nitrogen free extract was higher when compared to unfermented samples. The digestible (17480.64 kJ kg(-1)) and metabolisable (17389.08 kJ kg(-1)) energies as well as digestibility (966.95 g kg(-1)) of the fermentation residue were very high. The in vitro assessment of L. rhamnosus ATCC 7469 survival in simulated gastric conditions has shown high survival rate (87%). In addition, this bacterium has shown good antimicrobial activity against the most important pathogens and capability to produce exopolysaccharide on different sugars present in animal diet. After effective lactic acid fermentation, the residues could be recommended as a high quality feed for monogastric animals.

AB  - Maize (Zea mays L.) is one of the most important cereal crops, and as such, one of the most significant naturally renewable carbohydrate raw materials for the production of energy and multitude of different products. Many studies have shown that the kernel composition and starch structure of maize are highly influenced by genetic background of the maize. Maize grain consists of approximately 70% of starch, which makes it a very suitable feedstock for the bioethanol production. This study was conducted with aim to understand how different genetic background affects bioethanol yield and other fermentation properties of the selected maize genotypes in the process of maize grain-based bioethanol production. Twenty seven maize hybrids, including genotypes of standard chemical composition as well as specialty maize hybrids such as popping, waxy, white kernel and red kernel hybrids, developed at the Maize Research Institute, Zemun Polje, were investigated in this study. The lowest bioethanol yield of 7.25% w/w obtained for hybrid ZP 611k after 48 h of fermentation and the highest by genotype ZP 434 (8.96% w/w). A very significant positive correlation was determined between kernel starch content and the bioethanol yield after 48h of fermentation, as well as volumetric productivity (48h) (r=0.67). Between bioethanol yield after 48h of fermentation and soft endosperm content in kernel of the investigated ZP maize hybrids a very significant positive correlation was assessed (r=0.66). Higher overall bioethanol yields have been obtained from genotypes containing higher starch and lower protein and lipid contents.

AB  - This paper presents results of studies on qualities of maize dried distillers' grains with solubles (DDGS), as animal feed, which is a by-product from the process of maize grain-based bioethanol production. Twenty maize hybrids, developed at the Maize Research Institute, Zemun Polje, were used in this study. The moisture content in all DDGS samples was below 13% - the maximum value according to the Serbian Regulation. Furthermore, obtained results show that all observed DDGS samples had a high content of protein (29.58 - 36.08%), i.e. three-fold higher than in the initial raw material - maize grain. The digestibility of dry matter in samples of DDGS ranged from 74.09 (ZP Rumenka) to 82.41% (ZP 505). Based on obtained results, samples of DDGS were of high quality and therefore can be used as feed for the preparation of complete and concentrated feed.
AB  - Proizvodnjom bioetanola od zrna kukuruza dobija se sporedni proizvod poznat kao kukuruzna džibra. Na svaki litar bioetanola proizvedenog od zrna kukuruza nastaje oko 0,89 kg suve kukuruzne džibre. Ovaj sporedni proizvod industrije bioetanola predstavlja odličan izvor proteina i energije pa se zbog toga najčešće koristi kao komponenta smeša za ishranu domaćih životinja. Prihod od prodaje suve kukuruzne džibre mogao bi da ima pozitivan uticaj na ekonomsku isplativost proizvodnje bioetanola postupkom suvog mlevenja s obzirom da se ovim procesom jedna trećina kukuruznog zrna prevodi u suvu džibru. U ovom radu prikazani su rezultati ispitivanja kvaliteta suve kukuruzne džibre, kao hraniva za životinje. U istraživanju je korišćeno 20 hibrida kukuruza Instituta za kukuruz 'Zemun Polje '. Sadržaj suve materije kretao se od 90,47 (ZP Rumenka) do 91,87% (ZP 362), što ukazuje da je sadržaj vlage u svim uzorcima bio manji od 13%, maksimalne vrednosti prema Pravilniku o kvalitetu hrane za životinje. Rezultati su pokazali da su svi ispitani uzorci imali visok sadržaj proteina, između 29,58 (ZP 505) i 36,08% (ZP 611k). Pored toga uočeno je da je sadržaj proteina u suvoj džibri skoro utrostručen u odnosu na zrno kukuruza kao polaznu sirovinu. Svarljivost suve materije uzoraka suve kukuruzne džibre kretala se u rasponu od 74,09 (ZPRumenka) do 82,41% (ZP 505). Na osnovu dobijenih rezultata ustanovljeno je da su uzorci suve džibre svih ispitivanih hibrida dobrog kvaliteta i mogu se koristiti kao hranivo za pripremu potpunih i koncentrovanih smeša za ishranu životinja.

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  - 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  - BACKGROUND: Bioethanol is mostly produced from starchy parts of the corn grain kernel leaving significant amounts of valuable by-products such as dried distillers' grains with solubles (DDGS) which can be used as a substitute for traditional feedstuff. The suitability of six maize hybrids from Serbia was investigated for bioethanol and DDGS production. The correlation between physical and chemical characteristics of the grain, bioethanol yield and quality of the corresponding DDGS was assessed. RESULTS: All hybrids had very different chemical composition and physical characteristics which could allow various applications. The highest bioethanol yield (94.5% of theoretical) and volumetric productivity (2.01 g l1 h1) were obtained with hybrid ZP 434 and the lowest with ZP 611k. Regarding chemical composition, all DDGS samples manifested good properties as feed components. Their protein content was higher compared to the kernel. In addition, the samples showed high digestibility and high mineral content, especially of calcium and phosphorus. CONCLUSION: A hybrid ZP 434 was selected as the most promising bioethanol producer. This property is attributed to the highest level of soft endosperm which is more susceptible to starch-hydrolysing enzymes. A high yield potential per hectare makes it the best candidate for commercial bioethanol production. (c) 2012 Society of Chemical Industry

AB  - In recent decades, the expansion of alternative fuels production from crops traditionally used for food and animal feed has led to significant changes in the field of energy production, agriculture and food industry. Starch and sugar feed­stocks for ethanol production (corn, wheat, sugar beet, sugar cane, etc.) require increasing arable land to meet market demands for the biofuel production. Although intensive studies are being carried out in order to identify improved and more cost-effective methods for the utilization of lignocellulosic and communal waste in the production of alcohol fuel, the possibility of using dry distillers' grains with solubles (DDGS), by-product of bioethanol production from corn and wheat as well as alcoholic beverages industry, is now in focus. Application of DDGS in livestock and poultry diets in concentrations greater than traditional could positively affect the economic viability of this biofuel production, but also stabilize the current imbalance in the food and animal feed market. However, DDGS feedstuff should not be treated as a perfect substitute for corn, because the complexity of ration formulation determined at the farm or feedlot level is driven by energy and protein and other nutrient requirements, as well as their relative costs in the ration. Nevertheless, processing of corn by wet milling provides a multitude of co-products suitable for feedstuffs, food industry, pharmaceuticals, chemistry etc. Some of the most important wet milling co-products that have their use in feed­stuffs are corn gluten feed and corn gluten meal. The use of DDGS as a substitute for traditional feed could prevent indirect land-use changes associated with bio­fuel production, and therefore preserve the environmental destruction by saving the forests and permanent pastures. The use of distiller's grains can be beneficial to biofuel growth as this is an additional, the second largest, source of income accounting of 10-20% total income. In this paper, the possibilities of by-products from corn grain bioethanol and alcoholic beverages production are presented. Emphasis is placed on the dry distillers' grains with solubles, which is the most abundant and for researchers currently the most attractive co-product of bio­ethanol industry. Co-products from wet milling starch and ethanol production have not yet been thoroughly investigated and therefore represent an interesting subject for further research.

AB  - The rapid depletion of the world petroleum supply and the increasing problem
of greenhouse gas effects have strengthened the worldwide interest in alternative,
nonpetroleum sources of energy. Bioethanol accounts for the majority of
biofuel use worldwide, either as a fuel or a gasoline enhancer. Utilization of bioethanol
can significantly reduce petroleum use and exhaust greenhouse gas emission.
The production of this fuel has been increasing over the years, and has reached
the level of 73.9 billion liters during the year 2009. Even though for decades
ethanol production mainly depended on energy crops containing starch and sugar
(corn, sugar cane etc.), new technologies for converting lignocellulosic biomass
into ethanol are under development today. The use of lignocellulosic biomass, such
as agricultural residues, forest and municipial waste, for the production of biofuels
will be unavoidable if liquid fossil fuels are to be replaced by renewable and
sustainable alternatives. For biological conversion of lignocellulosic biomass, pretreatment
plays a central role affecting all unit operations in the process and is
also an important cost deterrent to the comercial viability of the process. The key
obstacles are: pretreatment selection and optimization; decreasing the cost of the
enzymatic hydrolysis; maximizing the conversion of sugars (including pentoses) to
ethanol; process scale-up and integration to minimize energy and water demand;
characterization and evaluation of the lignin co-product; and lastly, the use of the
representative and reliable data for cost estimation, and the determination of environmental
and socio-economic impacts. Currently, not all pretreatments are capable
of producing biomass that can be converted to sugars in high enough yield
and concentration, while being economically viable. For the three main types of
feedstocks, the developement of effective continuous fermentation technologies
with near to 100% yields and elevated volumetric productivities is one of the main
research subjects in the ethanol industry. The application of new, engineered enzyme
systems for cellulose hydrolysis, the construction of inhibitor tolerant pentose
fermenting strains, combined with optimized process integration promise
significant improvements.

AB  - The suitability of selected ZP maize hybrids for bioethanol and starch production was studied. The composition, physical and chemical traits, and the alcoholic fermentation of the maize hybrids hydrolysates were studied using Saccharomyces cerevisiae var. ellipsoideus yeast. The hybrid ZP 434 achieved the highest ethanol yield of 90.2% of the theoretical yield after 34 hr of fermentation, the maximum yield of 65.16%, and starch recovery of 93.14%. The hybrid ZP 544 obtained the lowest ethanol yield of 69.32%. The similar ethanol yield (approximately 79%) was also detected in Hybrids ZP 704wx and ZP 341 obtained similar ethanol yield of ≈ 79%, but differed very much on their starch content. The highest (74.13%) and the lowest (69%) starch contents were determined in hybrids ZP 704wx and ZP 341, respectively. This is an abstract of a paper presented at the 19th International Congress of Chemical and Process Engineering and 7th European Congress of Chemical Engineering (Prague, Czech Republic 8/28/2010-9/1/2010).

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.

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.
