Possible Mechanism of Pectin-Derived Oligosaccharides Influence on Gut Microbiota / Predloženi mehanizam uticaja oligosaharida dobijenih iz pektina na intestinalnu mikrobiotu
(Belgrade: University of Belgrade, 2018)
We prepared pectin-derived oligosaccharides (apple and citrus) and polygalacturonic acid-derived oligosaccharides, using alkaline hydrolysis by hydrogen peroxide, and analyzed them by Fourier Transform Infrared spectrometry. ...
Mechanochemical Preparation of CaO·ZnO – catalyst for Fatty Acids Methyl Esters Synthesis
(Belgrade : Serbian Ceramic Society, 2012)
One of the catalysts that show excellent activity in the methanolysis of vegetable oil under moderate reaction conditions is the mixture of CaO and ZnO oxides. In this study CaO•ZnO catalyst was synthesized by mechanochemical ...
Diatoms – invisible residents of Resavska Cave (eastern Serbia)
(Postojna, Slovenia : Organizing Commitee, 2nd Dinaric Symposium on Subterranean Biology, 2019)
Diatoms (Bacillariophyta) are widespread microorganisms that were found in different aquatic ecosystems, but also in other habitats, such as stone substrates exposed to air. There diatoms thrive with other phototrophic ...
Microbial degradation of petroleum hydrocarbons - in vitro study
(Federation of European Microbiological Societies (FEMS), 2020)
Pollution of the environment by petroleum products is a global problem, since its extensive exploitation in broad areas.
Microorganisms can degrade or transform toxic, petroleum derivates into harmless products with high ...
Analysis Of Microbial Community In Microbial Fuel Cell System
(Federation of European Microbiological Societies (FEMS), 2020)
This study was aimed to determine the number of various groups of microorganisms in order to
describe the microbial community present in a sample of the Danube river sediment used in
Microbial Fuel Cells (MFC) processes.
Efficiency of comercial enzymatic preparations in grain hydrolyses for preparation of substrates for alcoholic fermentation
(European association for chemical and molecular sciences (EuCheMS), 2006)
In this study, we investigated the optimal composition of substrates and tested optimal enzyme concentration for most efficient substrate degradation.
Bioactive pullulan based edible films with medicinal herbal extracts
(Belgrade : Society of Physical Chemists of Serbia, 2018)
In this work, pullulan based films with water extracts of medicinal herbs thyme and sage, were prepared. The resulting films were characterized by FT-IR spectroscopy and their antioxidant and antimicrobial activities were ...
Characterization of carbon fibrous materials obtained from tree wastes
(Serbian Chemical Society, Belgrade, 2010)
Carbon fibres can be obtained in rather wide variety of structures, compositions and properties, depending on the nature of the organic precursor and conditions of the process applied in their preparation. In order to get ...
Effect of Prebiotic Infant Formula on The Infant’s Gut Microbial Composition and Anthropometric Factors: Clinical Study
(University of Belgrade - Faculty of Chemistry, 2011)
The aim of this study was to investigate the influence of an infant formula containing added inulin and fructooligosaccharides on the gut microflora, as well as on the growth development and development of infants, compared ...
