| titleOfInvention | Construction and application of a bacterial laccase mutant LacAt and its expression strain |
| abstract | The invention discloses the construction and application of a bacterial laccase mutant LacAt and an expression strain thereof, wherein the protein sequence of the bacterial laccase mutant LacAt is shown in SEQ ID No: 1, and the gene sequence is shown in SEQ ID No: 2 . The invention uses laccase LacAn as the wild-type starting protein, constructs a mutant library through directed evolution, improves the enzyme properties, obtains the mutant enzyme by high-throughput screening technology and names it LacAt, and the enzyme activity of the fermentation broth is increased from the wild-type 560U/L. Up to 1125U/L, the protein expression of the mutant was 2 times higher than that of the wild-type enzyme. The mutant laccase LacAt is used for the decolorization of azo dyes directly 6, and the dye can be completely decolorized when no mediator is added, which improves the application ability of laccase, reduces the use cost and avoids secondary pollution, which is conducive to improvement Azo dye textile finishing process, reducing operating costs. |
