Diffusion screening method for estimation potential fungal producers of xylanase responsible for xylooligosaccharides production
(University of Belgrade - Faculty of ChemistrySerbian Biochemical Society, 2021)
Wild-type microorganisms from the environment represent a wide source of potential
enzyme producers. In order to determine whether an isolated microorganism produces an
enzyme of interest, various screen tests have ...
The influence of the starch coating on the magnetic properties of nanosized cobalt ferrites obtained by different synthetic methods
(Elsevier, 2021)
To investigate the magnetic behavior of starch-coated cobalt ferrites, well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted ...
X-rаy diffraction and SEM analysis of waste sulfur modification for use in concretes
(University of Belgrade - Faculty of Mining and Geology, 2021)
Secondary sulfur obtained as a by-product in the oil refining process is a major problem as an environmental pollutant. One of the possibilities for environmental protection is the use of sulfur obtained in this way as a ...
Production of fructooligosaccharides by Aspergillus welwitschiae inulinase enzyme complex, obtained on natural substrate
(Sociedade Portuguesa de Química, 2021)
Fructooligosaccharides (FOS) are used in the human diet thanks to their prebiotic effect and they are generally regarded as safe [1]. The increase in the functional food that contains prebiotics, has been tremendous over ...
