Description
Laccase (Laccase E.C. 1. 10. 3. 2) is a glucoproteinase containing copper. It can catalyze phenols and its derivatives, aromatic amine and its derivatives, carboxylic acids and its derivatives, steroid hormone, biochrome, organometallic compounds and non-phenols substrate.
Abbr
Laccase, Native (White rot fungi)
Applications
For indigo-dye-fading technique of jean processing by using laccase and catalysis enzymes in jean-washing industry, For selectively catalyze lignin-degradation and pulp bleaching by using laccase combined medium and xylanase. It is also a new environment friendly technique in wastepaper deinking process. For chlorophenols organic compounds degradation of wastewater treatment (which in line with pH requirements of laccase). For baking. For extract sugar. It can raise color value remaining. For others using as fiberboard adhesive, hair dyeing, lacquer dyeing film formation, crosslinking agent and biological measurement.
Unit Definition
1 unit of laccase equals to the amount of enzyme, which oxidized 1 umol ABTS at 30°C in 1 min.
Thermal stability
20 - 60°C
Stability
12 months at 4°C, activity remain ≥90%. Increase dosage after shelf life.
Storage
Should be stored in a cool place to avoid effect of high temperature.
