Degradation of epigallocatechin and epicatechin gallates by a novel tannase TanHcw from Herbaspirillum camelliae

Microbial Cell Factories, 2021
Background Herbaspirillum camelliae is a gram-negative endophyte isolated from the tea plant. Both strains WT00C and WT00F were found to hydrolyze epigallocatechin-3-gallate (EGCG) and epicatechin-3-gallate (ECG) to release gallic acid (GA) and display ...

Selection of tannase-producing Aspergillus niger strains [PDF]

Brazilian Journal of Microbiology, 2001
The aim of this work was to select strains of Aspergillus niger for tannase production. Growth of colonies in plates with tannic acid-containing medium indicated their ability to synthesize tannase. Tannase activity was also measured in solid-state fermentation. A. niger 11T25A5 was the best tannase producer (67.5 U.g-1/72 hours of fermentation).

Effect of Enzyme Treatment on Physicochemical and Phytochemical Properties of Guava Puree

Food Science &Nutrition, Volume 13, Issue 11, November 2025.
Treating guava puree with 600 ppm Bioguavase for 3 h at 30 C effectively improves clarity while minimizing nutrient degradation. These conditions are suitable for producing a clarified juice by centrifugation after enzyme treatment of the puree. This protocol is recommended for industrial‐scale guava juice processing to enhance product quality and ...

Basidiomycete Yeasts of Wine Grapes and Their Potential Applications in Winemaking

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 6, November 2025.
ABSTRACT Vineyards support highly diverse communities of native yeasts, but only a small proportion are fermentative ascomycetes capable of alcoholic fermentation. Many non‐fermentative species are also present, including a range of metabolically active basidiomycete yeasts that can influence wine aromatic profiles, especially in the early stages of ...
