Abstract

Graphical abstract: Highlights: Lignin-first biorefinery attracts attention for aromatic chemicals and biofuels. Laccase is an excellent green catalyst for lignin biodegradation. Thermostable laccase was better in lignin biodegradation at industrial condition. Three major approaches in thermostable laccase discovery are elucidated thoroughly. Abstract: As the most abundant aromatic polymers on the Earth, lignin has great potential to produce biofuels and aromatic chemicals due to their high carbon content and low oxygen content. Lignin-first biorefinery methods have attracted increasing attention recently for their high-value of aromatic chemicals, and high biofuels productivity from lignocellulosic wastes. Thermostable laccase has proven to be an excellent alternative catalyst in degrading lignin for its versatile catalytic abilities under industrial conditions and pollution-free by-products. Thermostable laccases can be found in native extreme environments or modified by biologically based technologies such as gene recombination expression and enzyme direct evolution. This review demonstrated thermostable laccases and their application in lignin degradation. Future research should focus more on the investigation of the reaction of thermostable laccases with lignin substrates.
