Bacterial cellulose (BC) is a natural biopolymer metabolized by Gram-negative bacteria strains in carbon- and nitrogen-rich media. Due to its purity, biodegradability, biocompatibility outstanding mechanical properties, it considered be an exceptional biomaterial with versatile scientific commercial applications. The current review presents data concerning the assembly, structural properties be...

Non-naturally branched polysaccharides were prepared homogeneously by reaction of cellulose in N,N-dimethyl acetamide/LiCl and the ionic liquid 1-N-butyl-3-methylimidazolium chloride with 2,3,4,6-tetraacetyl-1-bromo-α-D-glucopyranoside in the presence of triethylamine as base. Degrees of substitution up to 0.58 were realized. The samples were soluble in dimethyl sulphoxide and water. NMR spectr...

Abstract: Enhanced leaf proline, soluble sugar and soluble protein contents with sever salinity stress can improve stomatal conductance and Relative water content. This can inhibit dry matter depletion due to salinity stress, so can be used for screening of safflower cultivars under salinity stress. To evaluate the changes in leaf proline, soluble sugars, glycinebetaine and protein conte...

Food, feed and beverage processing brings tannins into contact with macromolecules, such as proteins polysaccharides, leading to different chemical physical interactions. The interactions of are well known but less is about the affinity polysaccharides. We used bacterial cellulose from nata de coco a model compound investigate how interact by adsorption measurements using UPLC-DAD. also explore...

The molten salt hydrate, lithium chloride (LiCl)/urea/water has previously been shown to swell cellulose, but there has so far been no work done to explore its effect on other polysaccharides. In this paper we have investigated the solvent effects of LiCl/urea/water on four natural polysaccharides. Fenugreek gum and xyloglucan, which are both highly branched, were found to increase in viscosity...

Chicken egg yolk immunoglobulin (IgY) is a superior alternative to mammalian immunoglobulin. However, the practical application of IgY in research, diagnostics, and functional food is limited due to complex or time-consuming purification procedures. The objective of this study was to develop a simple, safe, large-scale separation method for IgY from egg yolk. Egg yolk was diluted with 6-fold de...
