From raw starch degrading α-amylase to transglycosylase by single point mutation
(University of Belgrade, 2021)
Understanding the structural peculiarities and properties of both, raw starch as a substrate and raw starch digesting amylases (RSDA) as an enzymes is needed for efficient application in food and other industries. Although ...
Termodinamička svojstva i modelovanje međumolekulske interakcije dvokomponentne smeše limonena i hloroforma / Thermodynamic properties and modeling intermolecular interaction of binary mixture of limonene and chloroform
(Belgrade : Serbian Chemical Society, 2021)
U cilju proučavanja termodinamičkih svojstava binarne smeše limonen + hloroform eksperimentalno su određene gustine (ρ), viskoznosti (η) i indeksi refrakcije (nD) za ovu smešu. Eksperimentalna merenja su rađena u opsegu ...
Antibacterial activity of polypiridinearene ruthenium(II) complexes
(University of Belgrade - Faculty of ChemistrySerbian Biochemical Society, 2021)
Few studies concerning antibacterial activity of ruthenium complexes have been published but all of them have been performed on small limited number of strains 1,2. In this study complex 1 ([(η6-toluene)Ru(ppf)Cl]PF6) and ...
Production of polyglutamic acid by Bacillus sp: Strains selection, optimization, batch fermentation and characterization
(University of Belgrade - Faculty of ChemistrySerbian Biochemical Society, 2021)
Polyglutamic acid (PGA) is an anionic, non-toxic natural polymer that consists of D- and L-glutamic acid. Glutamic acids that makeup PGA create bonds between α-amino and γ-carboxyl groups. PGA can be found on the surface ...
