Hypothesis

Can the lcc1 gene from Trametes trogii be successfully expressed in Pichia pastoris to produce a functional laccase enzyme?

Conclusion

The lcc1 gene from T. trogii was successfully expressed in P. pastoris, resulting in a recombinant laccase with potential industrial applications.

Supporting Evidence

  • The recombinant laccase was produced at a yield of 17 mg/l.
  • The enzyme showed high activity in the presence of organic solvents.
  • Decolourization of synthetic dyes was significantly enhanced with redox mediators.

Takeaway

Scientists took a gene from a fungus and put it into yeast to make an enzyme that can help break down dyes and other pollutants.

Methodology

The lcc1 cDNA was expressed in Pichia pastoris using the alcohol oxidase promoter, and the recombinant enzyme was purified and characterized.

Limitations

The study did not explore the long-term stability of the enzyme in various industrial conditions.
