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)

In a new approach to microbial gallic acid production by Aspergillus fischeri MTCC 150, 40gL(-1) of tannic acid was added in two installments during the bioconversion phase of the process (25gL(-1) and 15gL(-1) at 32 and 44h respectively). The optimum
