AB  - This study provides a detailed analysis of the lignocellulolytic activity of a new isolate Stereum gausapatum F28, a Serbian autochthonous fungi, on beechwood sawdust supplemented with cheap waste, sugar beet molasses still age. Advanced multiple response optimization techniques were applied to improve ligninolytic and reduce hydrolytic activity as a requirement for potential biorefinery use. The applied techniques were supposed to select cultivation conditions that would give manganese peroxidase and laccase activities above 0.84 and 0.12 U g(-1) substrate, respectively, and cellulase and xylanase activities below 1.12 and 1.4 U g(-1) substrate. The optimal cultivation conditions that met the set requirements included molasses stillage concentration of 10 %, substrate moisture content of 53 %, incubation temperature of 23.5 degrees C, and pH 5.2. The research showed that the addition of molasses stillage had a positive effect on enzyme production and that the optimal stillage concentration differed depending on the enzyme type (for laccase it was   lt 5 %, manganese peroxidase approximate to 12 %, cellulase approximate to 21 % and xylanase approximate to 16 %), which should be taken into consideration when optimizing the desired process..

AB  - Lactic acid is an important chemical for food industry and monomer for production of biodegradable polymers. Emerging technologies for sustainable fermentative production of food additives include the utilization of by-products and wastes as substrates. Problem of stillage disposal, as a by-product with significant ecological imprint, is not adequately solved in Serbia and its utilization as a substrate for fermentation could be a promising strategy. Lactobacillus rhamnosus ATCC 7469 was selected for evaluation of optimal inoculum and initial sugar concentration for effective lactic acid and biomass production. Under the selected conditions (5% of inoculum and 55 g L-1 of initial sugar concentration) lactic acid yield of 92.3%, volumetric productivity of 1.49 g L-1 h-1 and number of viable cells of 109 CFU ml-1 were achieved. High number of viable cells indicates that the fermentation media remained after lactic acid removal could be used as a high-quality animal feed.
AB  - Mlečna kiselina se koristi kao acidulant, konzervans i poboljšivač ukusa u prehrambenoj industriji i kao monomer za proizvodnju biodegradabilnih polimera. Nove tehnologije za održivu fermentacionu proizvodnju aditiva u prehrambenoj industriji baziraju se na korišćenju sporednih i otpadnih proizvoda kao supstrata. Problem odlaganja džibre, kao sporednog proizvoda koji značajno zagađuje životnu sredinu, nije adekvatno rešen u Srbiji pa bi korišćenje džibre za fermentacionu proizvodnju mlečne kiseline moglo biti jedno od rešenja. U ovom istraživanju, ispitivana je proizvodnja mlečne kiseline na džibri od otpadnog hleba pomoću bakterija mlečne kiseline. Najviši prinos ostvaren je u fermentaciji sa Lactobacillus rhamnosus ATCC 7469. Ovaj soj je korišćen za dalji odabir odgovarajuće početne koncentracije inokuluma i šećera za efikasnu proizvodnju mlečne kiseline i biomase. Sa početnom koncentracijom šećera od 55 g L-1 i koncentracijom inokuluma od 5% ostvaren je prinos mlečne kiseline od 92,3%, produktivnost od 1,49 g L- h-1 i broj ćelija 109 CFU mL-1. Prinosi i produktivnosti koji su ostvareni na džibri bez dodatka mineralnih materija i izvora azota su visoki u poređenju sa vrednostima na sličnim otpadnim supstratima dosada objavljenim u literaturi, što ukazuje da bi džibra mogla biti dobar supstrat za industrijsku proizvodnju mlečne kiseline. Zbog velikog broja živih ćelija, zaostali medijum nakon mlečno-kiselinske fermentacije mogao bi se koristiti kao kvalitetna stočna hrana.
