Description

Tannase enzyme, also known as tannin acyl hydrolase (EC 3.1.1.20), is a specialized enzyme that catalyzes the hydrolysis of ester bonds present in gallotannins, complex tannins, and gallic acid esters, resulting in the release of gallic acid. This enzyme is of significant industrial interest due to its ability to break down these complex molecules into simpler compounds.

Applications of Tannase Enzyme

1.Food Industry: Tannase is widely used as a clarifying agent in the manufacturing of instant tea, beer, fruit juices, and some wines. It helps in improving the clarity and taste by reducing the astringency caused by tannins.

2.Pharmaceutical Industry: Tannase plays a crucial role in the production of gallic acid, an important intermediary compound in the synthesis of the antibacterial drug, trimethoprim. Gallic acid is also used in the synthesis of propyl gallate, a potent antioxidant.

3.Environmental Applications: Tannase is used in treating tannin-polluting industrial effluents and agricultural wastes, helping in reducing environmental pollution.

4.Animal Feed: Tannase can be used to reduce tannin levels in animal feed, improving the nutritional value and digestibility of the feed.

Production and Sources

Tannase can be produced by various microorganisms, including fungi such as Aspergillus, Penicillium, Fusarium, and Trichoderma, as well as bacteria and yeasts. The enzyme is typically produced through fermentation processes, and efforts have been made to improve its production, recovery, and purification processes.

Properties of Tannase

· Molecular Weight: Tannases have a vast molecular weight range from 31–310 kDa.

· Stability: They exhibit stability across a broad range of pH (3–10) and temperature (30–70°C).

· Substrates: Tannins are the primary substrates, and the enzyme can also perform a transesterification reaction for the production of propyl gallate.

Recent Advances

Recent research has focused on optimizing the production of tannase using low-cost substrates like agricultural wastes, which not only reduces the cost but also helps in waste management. Additionally, advancements in recombinant tannase manufacturing and the development of efficient downstream processing techniques are crucial for lowering production costs and improving enzyme recovery.

Tannase enzyme's versatility and its applications in various industries make it a subject of ongoing research and development, aiming to enhance its efficiency and expand its industrial applications.
