AB  - The aims of this research were to investigate the potential for improvement of bioethanol fermentation by microwave pre-treatment of triticale, as well as the possibility of using triticale stillage (a by-product of bioethanol fermentation) as a suitable medium for lactic acid fermentation, either without or with the optimal addition of CaCO3. The results showed that an adequate microwave pre-treatment (270 and 450W) marginally improved bioethanol production, giving a slightly higher yield of the bioethanol produced (by 3.95%). Lactobacillus fermentum PL-1 was used for subsequent lactic acid fermentation of the stillage that remained after bioethanol fermentation. Results showed higher pH decrease and higher acidity in the samples without the addition of CaCO3. Consequently, higher concentrations of L- and D-lactic acid were determined in the samples with the addition of CaCO3, as well as better viability of cells and the complete glucose utilization.

AB  - Adjuncts are also used in beer production to increase beer stability, and possibly to reduce the production costs. Triticale, the first man-made cereal, is the product of a cross between wheat and rye. In this study the possibility of triticale application as the partial substitute for barley malt in wort production was investigated. For wort production two series of experiments were performed in which triticale variety Adonis was used as the substitute for barley malt in grist with and without the addition of commercial enzyme Ultraflo Max. Triticale was added in each of the carried series of experiments as the substitute for malt: 0, 10, 30, 50, and 70% in grist. With the increase in the content of triticale in the grist, viscosity increased. The addition of commercial enzyme Ultraflo Max reduced wort viscosity. The obtained results indicate that worts produced with the addition of triticale variety Adonis in grist had good analytical quality parameters.

AB  - Brewer’s spent grain is the major by-product in beer production. It is produced in large quantities (20 kg per 100 L of produced beer) throughout the year at a low cost or no cost, and due to its high protein and carbohydrates content it can be used as a raw material in biotechnology. Biotechnological processes based on renewable agro-industrial by-products have ecological (zero CO2 emission, ecofriendly by-products) and economical (cheap raw materials and reduction of storage costs) advantages. The use of brewer’s spent grain is still limited, being basically used as animal feed. Researchers are trying to improve the application of brewer’s spent grain by finding alternative uses apart from the current general use as an animal feed. Its possible applications are in human nutrition, as a raw material in biotechnology, energy production, charcoal production, paper manufacture, as a brick component, and adsorbent. In biotechnology brewer’s spent grain could be used as a substrate for cultivation of microorganisms and enzyme production, additive or yeast carrier in beer fermentation, raw material in production of lactic acid, bioethanol, biogas, phenolic acids, xylitol, and pullulan. Some possible applications for brewer’s spent grain are described in this article, including pre-treatment conditions (different procedures for polysaccharides, hemicelluloses and cellulose hydrolysis), working microorganisms, fermentation parameters and obtained yields. The chemical composition of brewer’s spent grain varies according to barley variety, harvesting time, malting and mashing conditions, and a quality and type of unmalted raw material used in beer production. Brewer’s spent grain is lignocellulosic material rich in protein and fiber, which account for approximately 20 and 70% of its composition, respectively.

AB  - BACKGROUND: Bioethanol produced from renewable biomass, such as sugar, starch or lignocellulosic materials, is one of the alternative energy resources that is environmentally friendly. Triticale crops have a high yield as well as a high starch content and amylolytic enzyme activity and are therefore considered to be ideal for bioethanol production. RESULTS: This study examined the feasibility of ultrasound pretreatment to enhance the release of fermentable sugars from triticale meal during pretreatment and consequently increase bioethanol yield in the simultaneous saccharification and fermentation (SSF) process by Saccharomyces cerevisiae yeast. Ultrasonic pretreatment effectively increased the glucose and maltose content after liquefaction by 15.71% and 52.57%, respectively, compared with the untreated control sample under determined optimal conditions of sonication (5 min, 60 degrees C). The ultrasound pretreatment consequently improved bioethanol production during SSF processing since the bioethanol content was increased by 10.89%. CONCLUSION: Taking into consideration significant process parameters obtained in the SSF process of triticale meal with ultrasound pretreatment at 60 degrees C, the process time may be reduced from 72 to 48 h. At that point of the SSF, maximum bioethanol content of 9.55% (w/v), bioethanol yield of 0.43 g g(-1) of triticale starch, and percentage of the theoretical bioethanol yield of 84.56% were achieved.

AB  - Triticale shows many agronomic advantages including tolerance of acid soils, light soils, and dry conditions. This crop can be used for the ethanol production, and 8 triticale varieties were examined for it. The aim of the research was to choose a triticale variety with the lowest Falling number and the highest ethanol yield. In further research, the main aim was to see if the triticale stillage (produced during the ethanol production) can be used for the lactic acid production. According to technological parameters, the best variety is Odisej. Thermal preparation of triticale was made with distilled and tap water, but without noticeable differences in the ethanol yield. During lactic acid fermentation higher acidity was recorded in the samples without agitation, while the concentration of D- and L- lactic acid was higher in the samples with agitation. Utilization of carbohydrates was the same in both cases. The Odisej variety has the best technological characteristics, low Falling number, high α- amylase activity, no need for technical enzymes during the preparation process, as well as a high ethanol yield. Triticale stillage is a good medium for the lactic acid production, which can be used for natural preservation of stillage and its application in feed.
AB  - Tritikale ima mnogo agronomskih prednosti, i može rasti na kiselim i siromašnim zemljištima, kao i pri sušnim uslovima. Tritikale se može koristiti za proizvodnju bioetanola, i ispitano je 8 sorti ovog žita. Cilj rada je bio izabrati sortu tritikalea, sa najnižim brojem padanja i najvišim prinosom bioetanola. Dalji cilj istraživanja je bio da se ispita da li džibra dobijena nakon proizvodnje bioetanola može da se koristi za proizvodnju mlečne kiseline. Na osnovu tehnoloških parametara najbolja sorta je Odisej. Proces termičke pripreme tritikalea izvođen je sa destilovanom i vodom za piće, pri čemu nisu uočene razlike u prinosu bioetanola.

abstract = "Triticale shows many agronomic advantages including tolerance of acid soils, light soils, and dry conditions. This crop can be used for the ethanol production, and 8 triticale varieties were examined for it. The aim of the research was to choose a triticale variety with the lowest Falling number and the highest ethanol yield. In further research, the main aim was to see if the triticale stillage (produced during the ethanol production) can be used for the lactic acid production. According to technological parameters, the best variety is Odisej. Thermal preparation of triticale was made with distilled and tap water, but without noticeable differences in the ethanol yield. During lactic acid fermentation higher acidity was recorded in the samples without agitation, while the concentration of D- and L- lactic acid was higher in the samples with agitation. Utilization of carbohydrates was the same in both cases. The Odisej variety has the best technological characteristics, low Falling number, high α- amylase activity, no need for technical enzymes during the preparation process, as well as a high ethanol yield. Triticale stillage is a good medium for the lactic acid production, which can be used for natural preservation of stillage and its application in feed., Tritikale ima mnogo agronomskih prednosti, i može rasti na kiselim i siromašnim zemljištima, kao i pri sušnim uslovima. Tritikale se može koristiti za proizvodnju bioetanola, i ispitano je 8 sorti ovog žita. Cilj rada je bio izabrati sortu tritikalea, sa najnižim brojem padanja i najvišim prinosom bioetanola. Dalji cilj istraživanja je bio da se ispita da li džibra dobijena nakon proizvodnje bioetanola može da se koristi za proizvodnju mlečne kiseline. Na osnovu tehnoloških parametara najbolja sorta je Odisej. Proces termičke pripreme tritikalea izvođen je sa destilovanom i vodom za piće, pri čemu nisu uočene razlike u prinosu bioetanola. Tokom mlečnokiselinske fermentacije uočena je nešto veća kiselost kod uzoraka bez mešanja, veće koncentracije D- i L- mlečne kiseline kod uzoraka sa mešanjem, dok je utrošak glukoze bio isti u oba slučaja.

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  - In this paper, the bioethanol production with the thin stillage recirculation in mashing was investigated. The mashing was performed with recirculation of: 0, 10, 20 and 30% of the thin stillage. The thin stillage recirculation was repeated six times. In the experiment without the thin stillage, the recirculation bioethanol yield (compared to the theoretical yield) was 97.96%, which implicates that the experiment conditions were chosen and performed well. With the addition of the thin stillage, the bioethanol yield increased and was above 100 %. Higher bioethanol yield than 100 % can be explained by the fact that the thin stillage contains carbohydrates, amino acids and yeast cells degradation products. The bioethanol yield increased with the increased number of thin stillage recirculation cycles. Dry matter content in fermenting slurry increased with the increased thin stillage quantity and the number of the thin stillage recirculation cycles (8.04 % for the first and 9.40 % for the sixth cycle). Dry matter content in thin stillage increased with the increased thin stillage quantity and the number of thin stillage recirculation cycles. Based on the obtained results it can be concluded that thin stillage recirculation increased the bioethanol yield. The highest bioethanol yields were obtained with recirculation of 10% thin stillage.

AB  - Bioethanol produced from renewable biomass, such as sugar, starch, or lignocellulosic materials, is one of the alternative energy resources, which is both renewable and environmentally friendly. Although, the priority in global future ethanol production is put on lignocellulosic processing, which is considered as one of the most promising second-generation biofuel technologies, the utilization of lignocellulosic material for fuel ethanol is still under improvement. Sugar-based (molasses, sugar cane, sugar beet) and starch-based (corn, wheat, triticale, potato, rice, etc.) feedstock are still currently predominant at the industrial level and they are, so far, economically favorable compared to lingocelluloses. Currently, approx. 80 % of total world ethanol production is obtained from the fermentation of simple sugars by yeast. In Serbia, one of the most suitable and available agricultural raw material for the industrial ethanol production are cereals such as corn, wheat and triticale. In addition, surpluses of this feedstock are being produced in our country constantly. In this paper, a brief review of the state of the art in bioethanol production and biomass availability is given, pointing out the progress possibilities on starch-based production. The progress possibilities are discussed in the domain of feedstock choice and pretreatment, optimization of fermentation, process integration and utilization of the process byproducts.

AB  - Influence of ultrasound on triticale was investigated. Triticale is a cereal characterized with high yields per hectare and its ability to grow on marginal lands. It's most frequently used as animal feed supplement or in bread industry in combination with wheat flour. Nowadays, it's more widely used as a unmalted raw material in brewing industry. In this paper, samples of triticale variety Odyssey (crop 2008) were obtained from Institute of Field and Vegetable Crops Novi Sad, from Rimski Šančevi location. Due to constant need for more efficient production in brewing technology, new treatments of raw material have emerged. With the use of ultrasound treatment, particle sizes of triticale obtained from milling process can be reduced up to 20 times which benefits to liquefaction and saccharification of starch. In this paper, influence of ultrasound on triticale starch is analyzed using 2x2,5 and 2x5 minute ultrasound treatment with temperature regimes of 50°C and 60°C for duration of 65, 85 and 125 minutes. Ultrasound treatments of triticale mash gave both positive and negative results depending on applied time of ultrasound treatment and used temperature treatment. Best results were obtained using 2x2,5 minute of ultrasound treatment with temperature treatment of 60°C for duration of 125 minutes which would result in better degradation of triticale flour and benefit production of final product-beer. .
AB  - Ispitivan je uticaj ultrazvuka na proces razgradnje tritikalea. Tritikale je vrsta strnog žita sa visokim prinosima, otporna na poleganje sa mogućnošću uzgoja na marginalnim zemljištima. Najčešće se koristi kao dodatak u ishrani stoke ili kao dodatak pšeničnom brašnu u pekarskoj industriji dok se danas sve češće upotrebljava kao zamena dela slada u industriji proizvodnje piva. U ovom radu je korišćena sorta tritikalea Odisej (žetve 2008) iz selekcionih ogleda Instituta za ratarstvo i povrtarstvo u Novom Sadu sa lokaliteta Rimski Šančevi. Zbog stalne potrebe ka unapređenju i ekonomičnijoj proizvodnji javili su se novi postupci obrade skrobnih sirovina kao što je to upotreba ultrazvučnog tretmana. Ultrazvučnim tretmanom se može postići bolje usitnjavanje sirovine, što dovodi do smanjenja veličine čestica i do 20 puta i na taj način omogućava bolju likvefakciju i saharifikaciju skroba. Primenjeni su ultrazvučni tretmani u trajanju od 2x2,5 i 2x5 minuta uz temperaturne tretmane na 50°C i 60°C u trajanju od 65, 85 i 125 minuta. Dobijeni rezultati pokazuju i pozitivna i negativna dejstva ultrazvučnog tretmana u procesu razgradnje tritikalea u zavisnosti od primenjene dužine ultrazvučnog tretmana i odabranog temperaturnog tretmana. Najbolji rezultati se dobijaju primenom ultrazvučnog tretmana u trajanju od 2x2,5 minuta uz temperaturni tretman na 60°C za 125 minuta, čime bi se postigla brža i bolja razgradnja brašna tritikalea u varionici i dobijanje većih količina gotovog proizvoda-piva uz ekonomičniji rad. .

abstract = "Influence of ultrasound on triticale was investigated. Triticale is a cereal characterized with high yields per hectare and its ability to grow on marginal lands. It's most frequently used as animal feed supplement or in bread industry in combination with wheat flour. Nowadays, it's more widely used as a unmalted raw material in brewing industry. In this paper, samples of triticale variety Odyssey (crop 2008) were obtained from Institute of Field and Vegetable Crops Novi Sad, from Rimski Šančevi location. Due to constant need for more efficient production in brewing technology, new treatments of raw material have emerged. With the use of ultrasound treatment, particle sizes of triticale obtained from milling process can be reduced up to 20 times which benefits to liquefaction and saccharification of starch. In this paper, influence of ultrasound on triticale starch is analyzed using 2x2,5 and 2x5 minute ultrasound treatment with temperature regimes of 50°C and 60°C for duration of 65, 85 and 125 minutes. Ultrasound treatments of triticale mash gave both positive and negative results depending on applied time of ultrasound treatment and used temperature treatment. Best results were obtained using 2x2,5 minute of ultrasound treatment with temperature treatment of 60°C for duration of 125 minutes which would result in better degradation of triticale flour and benefit production of final product-beer. ., Ispitivan je uticaj ultrazvuka na proces razgradnje tritikalea. Tritikale je vrsta strnog žita sa visokim prinosima, otporna na poleganje sa mogućnošću uzgoja na marginalnim zemljištima. Najčešće se koristi kao dodatak u ishrani stoke ili kao dodatak pšeničnom brašnu u pekarskoj industriji dok se danas sve češće upotrebljava kao zamena dela slada u industriji proizvodnje piva. U ovom radu je korišćena sorta tritikalea Odisej (žetve 2008) iz selekcionih ogleda Instituta za ratarstvo i povrtarstvo u Novom Sadu sa lokaliteta Rimski Šančevi. Zbog stalne potrebe ka unapređenju i ekonomičnijoj proizvodnji javili su se novi postupci obrade skrobnih sirovina kao što je to upotreba ultrazvučnog tretmana. Ultrazvučnim tretmanom se može postići bolje usitnjavanje sirovine, što dovodi do smanjenja veličine čestica i do 20 puta i na taj način omogućava bolju likvefakciju i saharifikaciju skroba. Primenjeni su ultrazvučni tretmani u trajanju od 2x2,5 i 2x5 minuta uz temperaturne tretmane na 50°C i 60°C u trajanju od 65, 85 i 125 minuta. Dobijeni rezultati pokazuju i pozitivna i negativna dejstva ultrazvučnog tretmana u procesu razgradnje tritikalea u zavisnosti od primenjene dužine ultrazvučnog tretmana i odabranog temperaturnog tretmana. Najbolji rezultati se dobijaju primenom ultrazvučnog tretmana u trajanju od 2x2,5 minuta uz temperaturni tretman na 60°C za 125 minuta, čime bi se postigla brža i bolja razgradnja brašna tritikalea u varionici i dobijanje većih količina gotovog proizvoda-piva uz ekonomičniji rad. .",
