Chemical modification of hemicellulose isolated from corncobs to obtain hydrogel for enzyme immobilization
(Society of Physical Chemists of Serbia, 2021)
Hemicellulose rich in xylan was isolated from corncobs. Functional groups were introduced first by
carboxymethylation and then by coupling with tyramine via carbodiimide-mediated reaction.
Obtained hydrogel was tested ...
Sesquiterpene lactones content in lettuce cultivars affected by microbiological fertilisers and seasons
(Serbian Plant Physiology Society, 2022)
The principal sesquiterpene lactones (lactucin, lactucopicrin, and its dihydro forms), known as contributors to bitter taste, were measured in green and red coloured lettuce using Ultra-performance liquid chromatography. ...
The usage of silicon fertilisation in order to mitigate the oxidative stress and to improve the resilience of barley subjected to drought
(Serbian Plant Physiology SocietyInstitute for Biological Research “Siniša Stanković” – National Institute of Republic of Serbia, University of BelgradeFaculty of Biology, University of Belgrade, 2022)
Drought causes huge agricultural and economic losses worldwide. Silicon (Si) is considered a
beneficial element for plants. It mitigates stress caused by salinity, drought, and high and low temperatures
