The pH and temperature sensitivity of the natural blue pigment phycocyanin from Arthrospira platensis limits its application as food colorant. This study examines the effect of protein stabilization by the anionic polysaccharide λ-carrageenan on phycocyanins color appearance at pH 2.5-6.0, unheated and after heat treatments (70/90 °C). Electrostati...
The aim of the present study was to investigate the effect of coadministration of the proton pump inhibitor (PPI) esomeprazole on the upper GI tract behavior and systemic exposure of mesalazine from two mechanistically different colon targeted delivery systems: Claversal (pH-dependent release) and Pentasa (prolonged release). To this end, gastric, ...

Both HClO and pH are essential players in multiple biological processes, which thus need to be controlled properly. Dysregulated HClO or pH correlates with many diseases. To meet these challenges, we need to develop highly competent probes for monitoring them. Over the years, despite a rich history of the development of HClO or pH probes, those tha...
Dissolved CO2 levels (pCO2) are increasing in lentic freshwaters across the globe. Recent studies have shown that this will impact the nutritional quality of phytoplankton as primary producers. However, the extent to which freshwater zooplankton may also be directly affected remains unclear. We test this in three model species representative of the...

Silver nanoparticles arose as a new weapon in the development of green synthesis of these nanoparticles using diverse natural resources such as plant leaf, microorganisms, and fruit extracts. Biosynthesis approach by using waste materials from plant is widely used as it is proven to be environmentally and cost friendly method. This study aims to id...

As the awareness on the ecological impact of chemical phosphate fertilizers grows, research turns to sustainable alternatives such as the implementation of phosphate solubilizing bacteria (PSB), which make largely immobile phosphorous reserves in soils available for uptake by plants. In this review, we introduce the mechanisms by which plants facil...
Separation of divalent salts and small organics plays a paramount in biorefinery and food industries. Nanofiltration (NF) membranes featuring suitable pore aperture ranges enables achievement of this goal, yet it fails in attaining a high liquid permeance and selectivity due to the presence of a highly crosslinked polyamide (PA) layer. In this work...
Evidence of weak interaction between ferric iron and extracellular polymeric substances of Acidithiobacillus ferrooxidan...
Although ferric iron in extracellular polymeric substances (EPS) was believed to be pivotal in bioleaching, the real existing form of ferric iron in EPS has remained poorly understood. In this study, whole cells of Acidithiobacillus ferrooxidans were used to study the composition and properties of EPS. The components sugars, proteins and uronic aci...
