Utilization of agro-industrial by-products as substrates for dextransucrase production by Leuconostoc mesenteroides T3: process optimization using response surface methodology
(Hemijska industrija, 2021)
Dextransucrase (DS) is a glucosyltransferase (E. C. 2.4.1.5) that catalyzes the transfer of glucosyl residues from sucrose to dextran polymer and liberates fructose. This enzyme isassociated with a wide application range ...
Influence of Pr3+ and CO32- Ions Coupled Substitution on Structural, Optical and Antibacterial Properties of Fluorapatite Nanopowders Obtained by Precipitation
(Metals, 2021)
Coupled substitution of fluorapatite (FAP) crystal lattice plays an important role in the engineering of optically active nanomaterials. Uniform fluorapatite nanopowders doped with praseodymium (Pr3+) and carbonate (CO32-) ...
ANTIFUNGAL POTENTIAL OF GARLIC ESSENTIAL OIL ON ASPERGILLUS SPECIES ISOLATED FROM FOOD / ANTIFUNGALNI POTENCIJAL ETARSKOG ULJA BELOG LUKA PREMA ASPERGILLUS VRSTAMA IZOLOVANIM IZ HRANE
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, 2021)
Aspergillus species are common contaminants of medium and low moisture foods. By their
metabolic activity, they cause food spoilage, leading to great economic damage. However, much
higher problem are toxigenic species, ...
ANALIZA MORFOLOGIJE KAVITACIONOG OŠTEĆENJA MARTENZITNOG NERĐAJUĆEG ČELIKA / ANALYSIS OF CAVITATION DAMAGE MORPHOLOGY OF MARTENSITIC STAINLESS STEEL
(Zenica : Faculty of Mechanical Engineering, 2021)
U radu je analizirana morfologija kavitacionog oštećenja martenzitnog nerđajućeg čelika. Za ispitivanje otpornosti na dejstvo kavitacije, u laboratorijskim uslovima je primenjena ultrazvučna vibraciona metoda sa stacionarnim ...
Pulverized river shellfish shells as a cheap adsorbent for removing of malathion from water: Examination of the isotherms, kinetics, thermodynamics and optimization of the experimental conditions by the response surface method
(University of Defence in Belgrade, 2021)
Introduction/purpose: In this study, we investigated the possibility of removing the organophosphorus pesticide malathion from water using a new adsorbent based on the biowaste of river shell shards from the Anodonta ...
