Design and characterization of alcalase-chitosan conjugates as potential biocatalysts
(Springer, New York, 2017)
In this study, alcalase (protease from Bacillus licheniformis) immobilization by adsorption, enzyme crosslinking and covalent enzyme binding to activated chitosan microbeads were examined. The biocatalysts highest activity ...
Diarylheptanoids from Alnus viridis ssp viridis and Alnus glutinosa: Modulation of Quorum Sensing Activity in Pseudomonas aeruginosa
(Georg Thieme Verlag Kg, Stuttgart, 2017)
Diarylheptanoids from the barks of Alnus viridis ssp. viridis (green alder) and Alnus glutinosa (black alder) were explored for anti-quorum sensing activity. Chemicals with anti-quorum sensing activity have recently been ...
A novel macroporous polymer-inorganic nanocomposite as a sorbent for pertechnetate ions
(The Royal Society of Chemistry, 2017)
A novel magnetic macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (mPGME) was prepared by suspension copolymerization and functionalized with diethylenetriamine (mPGME-deta). The samples were ...
Brachybacterium sp CH-KOV3 isolated from an oil-polluted environment-a new producer of levan
(Elsevier, 2017)
Various microorganisms isolated from polluted environments, such as Pseudomonas sp. and Micrococcus sp. can synthesize exopolysaccharides (EPSs) which are natural, non-toxic and biodegradable polymers. EPSs play a key role ...
Study of potential harmful elements (arsenic, mercury and selenium) in surface sediments from Serbian rivers and artificial lakes
(Elsevier, 2017)
This investigation examines surface sediment samples from rivers and artificial lakes (Serbia) to quantify levels of potentially harmful elements (As, Hg, and Se) and several ancillary elements (Al, Fe, Mn, Ca, Mg, C, H, ...

Occurrence of synthetic musk compounds in surface, underground, waste and processed water samples in Belgrade , Serbia
(Springer, New York, 2017)
This study assessed the state of waters in Belgrade regarding pollution with musk compounds as the target contaminants. Eleven of these compounds were alicyclic, two were macrocyclic, and one was polycyclic. Solid-phase ...
Implementation of 5S tools as a starting point in business process reengineering / Primena 5S alata kao polazne osnove u reinženjeringu poslovnih procesa
(University of Novi Sad, Technical faculty Mihajlo Pupin, Zrenjanin, 2017)
The paper deals with the analysis of elements which represent a starting point in implementation of a business process reengineering. We have used Lean tools through the analysis of 5S model in our research. On the example ...
Phenolic profiles, antioxidant activity and minerals in leaves of different grapevine varieties grown in Serbia
(Academic Press Inc Elsevier Science, San Diego, 2017)
This research was designed to determine phenolics content, radical scavenging activity and mineral composition of 22 grapevine leaves of diverse varietal origin. Samples were collected from two vineyards located in Central ...
Metabolomics study of Populus type propolis
(Elsevier, 2017)
Herein, we propose rapid and simple spectroscopic methods to determine the chemical composition of propolis derived from various Populus species using a metabolomics approach. In order to correlate variability in Populus ...
