What is laccase enzyme used for?

What is laccase enzyme used for?

Food Processing Industry. In food industry, laccase is used for the elimination of undesirable phenolic compound in baking, juice processing, wine stabilization, and bioremediation of waste water [2]. Laccase improves not only the functionality but also the sensory properties [107].

What is the meaning of laccase?

: a blue copper-containing oxidase occurring especially in the sap of lacquer trees and having an ability to produce lacquer from the sap and induce oxidation of certain polyhydroxy phenols (as urushiol)

Is laccase extracellular?

Fungal laccases are involved in sporulation, pigment production, fruiting body formation, stress defense, plant pathogenesis, and lignin degradation [27, 28]. Although most purified laccases are extracellular enzymes, wood-rotting fungi also contain intracellular laccases.

Where is laccase found?

Laccases are widely distributed in higher plants, bacteria, fungi, and insects. In plants, laccases are found in cabbages, turnip, potatoes, pears, apples, and other vegetables. They have been isolated from Ascomyceteous, Deuteromycteous and Basidiomycetous fungi to which more than 60 fungal strains belong [3].

What type of enzyme is laccase?

Laccases are the versatile enzymes which catalyze oxidation reactions coupled to four-electron reduction of molecular oxygen to water. They are multicopper enzymes which are widely distributed in higher plants and fungi. They are capable of degrading lignin and are present abundantly in many white-rot fungi.

What is extracellular laccase?

Laccases are the model enzymes for multicopper oxidases and participate in several applications such as bioremediation, biopulping, textile, and food industries. The molecular weights of partially purified laccase were 52 kDa for rice bran and 55 kDa for wheat bran.

How many enzymes are there in our body?

There are approximately 1300 different enzymes found in the human cell. These enzymes can combine with coenzymes to form nearly 100,000 various chemicals that enable us to see, hear, feel, move, digest food, and think.

How is laccase used in the food industry?

Laccase has also been widely used in the food industry. Increasing the stability of glucose is a major application of laccase in the food industry. The addition of laccase can improve the stability of the wine, thus reducing the amount of sulfur dioxide used.

What kind of enzyme is the laccase enzyme?

Laccase was first discovered in the toxicodendron vernicifluum. Subsequently, it was found that certain fungi also secreted the laccase. Laccase can catalyze the degradation of a variety of aromatic compounds, especially phenols, and is a natural environmentally friendly enzyme.
