설명

일반 설명

Tannase is an enzyme that is produced by several organisms such as plants, bacteria, fungi, and yeast. This enzyme is also found in plant sources such as tannin-rich vegetables, especially in the leaves, fruits, branches, and bark.

애플리케이션

Tannase from Aspergillus ficuum has been used:

• as a standard to determine the tannase activity of bacterial isolates
• to study its effects on the inhibitory activity of tannic acid on biofilm formation
• to obtain Proanthocyanidins (PA) by enzymatic hydrolysis of grape skin and seeds

생화학적/생리학적 작용

Tannase catalyzes the ester bonds located in complex tannins, gallo-tannins, and gallic acid esters, which results in the release of gallic acid. This enzyme can be used as a clarifying agent in the manufacture of beer, tea, wine, and juices and to treat tannin-polluting agricultural waste and industrial effluents.

단위 정의

1 U corresponds to the amount of enzyme which changes the absorbance at 310 nm by 1.0 per minute at pH 4.7 and 30°C (tannic acid as substrate, final volume 3 ml)
