Regulatory Mechanisms of Tannins on the Decomposition Rate of Mixed Leaf Litter in Submerged Environments [PDF]

Plants
Terrestrial cross-boundary inputs of leaf litter serve as a critical foundation for secondary productivity in freshwater ecosystems. The regulatory mechanisms of tannins in leaf litter on degradation rates under submerged conditions remain unclear.

Biosorption of Chromium from Textile Wastewater Using Mimosa pudica Tannin Gel

Equilibrium, 2021
. The heavy metal content is very dangerous because it can pollute the environment. One of the heavy metals waste commonly found in the textile industry is chromium (Cr). Mimosa pudica is a weed plant and its availability is very abundant.

The effect of wine age and tannin composition on tannin activity across consecutive Pinotage red wine vintages

OENO One, 2022
The effect of wine age on tannin chemistry and tannin activity values was investigated in red wine extracts according to a chemosensory approach. Sixteen Pinotage red wines of multiple vintages (2003-2018) were each isolated into four distinct polymeric ...

Tannins as Hemostasis Modulators [PDF]

Frontiers in Pharmacology, 2022
The hemostasis system is often affected by complications associated with cardiovascular diseases, which results in thromboembolic events. Compounds of plant origin and plant extracts are considered as a promising source of substances that could modulate the functioning of the hemostasis system and thus reduce the risk of thromboembolism.

Persimmon-derived tannin ameliorates the pathogenesis of ulcerative colitis in a murine model through inhibition of the inflammatory response and alteration of microbiota

Scientific Reports, 2021
Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) induced by dysregulation of the immune response in the intestinal mucosa. Although the underlying mechanisms of UC development are not fully understood, disruption of gut microbiota ...

Colloidal stability of tannins: astringency, wine tasting and beyond [PDF]

, 2008
Tannin-tannin and tannin-protein interactions in water-ethanol solvent mixtures are studied in the context of red wine tasting. While tannin self-aggregation is relevant for visual aspect of wine tasting (limpidity and related colloidal phenomena ...

Effect of protein-tannin ratio and tannin concentration on the bovine serum albumin (BSA)-based precipitation method for red wine tannin concentration

OENO One, 2011
Aims: The main objective of the study was to ascertain whether an existing protein precipitation assay could be simply modified to determine tannin at low concentration in wines. This was achieved by mixing a greater volume of wine to a smaller, but more

Response to dietary tannin challenges in view of the browser/grazer dichotomy in an Ethiopian setting : Bonga sheep versus Kaffa goats [PDF]

, 2015
It has been suggested that goats (typical browser) are better adapted to digest tannin-rich diets than sheep (typical grazer). To evaluate this, Bonga sheep and Kaffa goats were used in a 2x3 randomized crossover design with two species, three diets, and
