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  - Triticale stillage is a by-product of the bioethanol fermentation. It is used as the
addition to feed and needs the protection from spoiling and pathogens. Lactic acid
bacteria can be used for it, and triticale stillage is then used as a medium for their
growth and the lactic acid production. The aim of this work was to see if there is a
possibility for scale up of the lactic acid fermentation process (by increasing 10 times
medium volume), when an inoculum is Lactobacillus fermentum PL-1. Titrable acidity
and pH were measured during the lactic acid fermentation. Utilization of carbohydrates
and the concentrations of D- and L- lactic acid were determined by enzymatic kits.
Viability of the lactic acid bacteria cell was done by pour a plate method. There was no
difference in pH value during the process (medium volume changed from 25 to 250
mL), while titrable acidity was significantly lower. The L-lactic acid yield was also
smaller, but not significantly. Utilization of carbohydrates was complete in both cases,
and viability was better in the samples with the usual experimental design. Given
results indicate that the volume of the fermentation medium can be increased on a pilot
level, for example.

AB  - Triticale stillage is a by-product of bioethanol production. A research study was conducted in order to see if triticale stillage is adequate for lactic acid bacteria growth and lactic acid fermentation. Three Lactobacillus strains: Lactobacillus fermentum NRRL-B-75624, Lactobacillus fermentum PL-1, and Lactobacillus plantarum PL-4 were taken into consideration. Lactic acid fermentation was monitored by measuring pH value and titratable acidity. Lactobacillus fermentum PL-1 had the greatest decrease of pH values and increase of titratable acidity so it was chosen for future work. During the research, it was investigated how nutrient composition of triticale stillage and CaCO3 can influence lactic acid fermentation and CaCO3 role in cell protection. The nutrient composition of triticale stillage was satisfactory for lactic acid fermentation. The addition of CaCO3 helped in lactic acid fermentation. Although the titratable acidity in the samples with CaCO3 was lower than in the samples without CaCO3, the number of viable cells was higher for the samples with CaCO3, which showed that CaCO3 protected lactic acid cells from inhibition by lactic acid.
AB  - Džibra tritikalea predstavlja jedan od sporednih produkata tokom proizvodnje bioetanola. Glavna ideja istraživanja je bila da se istraži pogodnost džibre tritikalea kao podloge za uzgajanje bakterija mlečne kiseline i mlečnokiselinsku fermentaciju. Tokom rada su ispitivana tri soja bakterija mlečne kiseline: Lactobacillus fermentum NRRL-B-75624, Lactobacillus fermentum PL-1 i Lactobacillus plantarum PL-4. Tok mlečno-kiselinske fermentacije praćen je merenjem pH vrednosti uzorka, kao i određivanjem titrabilne kiselosti. Kod Lactobacillus fermentum PL-1 je zabeleženo najveće sniženje pH vrednosti, kao i porast titrabilne kiselosti, te je iz tih razloga izabran za dalji tok rada. Istraživanje je bilo usmereno i na to kako hranjivi sastav podloge i dodatak CaCO3 utiču na mlečno-kiselinsku fermentaciju, kao i na zaštitnu ulogu CaCO3 na ćelije bakterija mlečne kiseline. Hranjivi sastav džibre tritikalea se pokazao kao kompletna podloga za odvijanje mlečno-kiselinske fermentacije. Titrabilna kiselost je bila niža kod uzoraka sa dodatkom CaCO3, u odnosu na uzorke kojima nije dodat CaCO3, zbog formiranja Ca-laktata. Istovremeno je zabeležen veći broj vijabilnih ćelija u uzorcima kod kojih je dodat CaCO3, što ukazuje da CaCO3 ima zaštitnu ulogu na ćelije bakterija mlečne kiseline.

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  - Triticale is a very applicable crop for bioethanol production, and also provides a stillage that can be used as a feed. The main aim of this research was to investigate the possibility of transformation of unused stillage carbohydrate after bioethanol prooduction into the lactis acid fermentation, in order to produce a natural feed preservative. In this study Lactobacillus fermentum Pl-1 was used. Different pre-treatment were done during the preparation of bioethanol fermentation (by triticale autoamylolytic enzymes, technical enzymes and ultrasound), and thus 4 different samples of stillage were prepared. CaCO3 was added in one part of the samples. Results indicated a good conversion factor of glucose into the lactic acid, up to 1.55 after 72 hours of the treatment. The sample pre-treated only by triticale autoamylolytic enzymes had a small part of carbohydrtes utilised during the stillage preparation. As a result, there was more glucose available for lactic acid fermentation. Added CaCo3 probably improved the protection of Lactobacillus fermentum PL-1 cells, but it was not possible to see a real glucose conversion factor due to Ca-lactate formation. Therefore, the stillage produced after the bioethanol production is a very good medium for lactic acid production

AB  - Bioethanol produced by fermentation of biomass, such as sugar, starch, or lignocellulosic materials, is one of the most important renewable energy resources today. Beside the bioethanol, considerable amounts of by-products such as carbon dioxide, solid and liquid stillage are formed during the fermentation. Their further utilization could significantly increase the economy of bioethanol production. It is estimated that per 1hl of the produced bioethanol, approximately 13 hl of liquid thin stillage is formed. It contains high concentrations of organic and inorganic substances and must be pretreated before its disposal to water flows. In addition to recirculation of thin stillage and its reuse, production of soil fertilizers and various types of animal feed, the thin stillage can be used as a substrate for anaerobic fermentation for the production of butanol or especially lactic acid. Lactic acid has versatile application not only in food, pharmaceutical, leather and textile industries, but also as a chemical feedstock for the production of base chemicals (propylene glycol, propylene oxide, acrylic acid, acrylate esters, lactate ester and etc) or for the preparation of biodegradable polymers (poly lactic acid), medical sutures, and green solvents. The aim of this work was to select appropriate species for lactic acid fermentation of the corn thin stillage which is an inexpensive renewable substrate.

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. .
