The use of rhizospheric SynComs can be a new and sustainable strategy in the agrobiotechnology sector. The objective of this study was to create the most appropriate SynCom composition; examine the ability to dissolve natural rock phosphate (RP) from Morocco in liquid-modified NBRIP medium; determine organic acids, and phytohormones; and verify pla...

Background Lactic acid is one of the most important organic acids, with various applications in the food, beverage, pharmaceutical, cosmetic, and chemical industries. Optically pure forms of L- and D-lactic acid produced via microbial fermentation play an important role in the synthesis of biodegradable polylactic acid. Alternative substrates, incl...

Avena sativa (A. sativa) oats have recently made a comeback as suitable alternative raw materials for dairy substitutes due to their functional properties. Amylolytic and cellulolytic enzyme-assisted modifications of oats produce new products that are more appealing to consumers. However, the biochemical and functional alteration of products and ex...

After removing gluten residues from wheat processing by-products – starch and bran, they could be used for production of gluten-free products. Various plants and their extracts contain gluten decomposing proteases. For gluten hydrolysis, based on the previous research data, it was determined to use pineapple, kiwi, papaya juices and Nigella sativa...

Recently there is an increase in the number of consumers with gluten intolerance that causes expanding of the demand for gluten-free products. Gluten-free diet is unbalanced and usually has a higher percentage of calories from fat, less of carbohydrates, as well as low intake of non-starch polysaccharides. To solve this problem, new strategies are...

The influence of native lipids and additives of surface-active compounds on starch paste rheology was investigated. The aim of the study was to gain better understanding of mechanisms involved in starch gelatinization and how these structure changes of granules later affect rheological properties of pastes and gels. Starches from three main sources...

The effect of native lipids and additives of surface active compounds on starch short-term retrogradation and formed gel rheology was investigated. The main aim of the study was to correlate the findings of pasting analysis with the phenomena observed during starch retrogradation and gel formation as affected by the surface active compounds. Three...

The subject of the study was corn, wheat and potato starch before and after treatment with sodium hydroxide solution, with the aim to evaluate whether this solution is able to remove lipids and have any effect on the rheological properties of starch pastes and gels. Applying the DSC method, it was noted that after the treatment with the sodium hydr...

Mucoadhesivity of water-soluble polymers is an important factor, when testing their suitability for controlled drug delivery systems. For this purpose, the interaction of new cationic cellulose polyelectrolytes with lyophilized mucin was investigated by means of turbidimetric titration, microscopy and measurement of zeta potential and particle size...

Diimides 4,4'-oxydiphenylene diphthalylimide (PT-ODA-PT) and diphenylbiphenyltetracarboxyimide (A-BPDA-A) of an evident affinity to polyimides have been dispersed in a matrix of poly(4,4'-oxydiphenylene biphenyltetracarboxyimide) (BPDA-ODA). Changes in thermal and mechanical properties of BPDA-ODA films modified by diimides have been found to depen...

Synthesis of (co)polyimides from aromatic dianhydrides (pyromellitic dianhydride (PMDA). symmetric 3,3',4,4'-biphenyltetracarboxylic dianhydride (sBPDA)) and diamines (4,4'-oxydianiline (ODA), p-phenylenediamine (PDA)) commonly used for the production of commercial polyimides. as well as the preparation of their nanocomposites with SiO2 nanoparticl...

The interaction between polydiallyldimethylammonium chloride (PDADMAC) and KI or KBr, followed by changes in conformation of macromolecules, coil compaction, and counterion exchange, was detected by means of turbidimetry and viscometry. In aqueous solutions at presence of KI, PDADMAC rapidly binds iodine by the formation of polymer–iodine complexes...

An interaction between poly(diallyldimethylammonium chloride) and ammonium persulfate in aqueous solutions has been detected and studied by methods of turbidimetry and viscometry. Investigations were carried out with the cationic polymer of different molecular weight. It was shown that association between low-molecular-weight polyquaternary ammoniu...

Behaviour of the cationic flocculant, polyquaternary ammonium salt, in textile dye solutions containing traditional ingredients and finishing chemicals was investigated. It was shown that polyquaternary salt was prone to form complexes with anionic detergent, dispersing agent, thickeners, and some inorganic colloidal compounds. The role of such com...
