The breakdown of plant lignin modifies the structure of lignocelluloses, thus making carbohydrates accessible for efficient bioconversion. White-rot fungi produce ligninolytic enzymes such as lignin peroxidase, manganese peroxidase, laccases and various peroxidases, which mineralize lignin efficiently. We review here applications of ligninolytic enzymes for the delignification of lignocellulosic materials, the removal of recalcitrant organic pollutants, wastewater treatment, decolorization of dyes, soil treatment, conversion of high molecular weight coal fractions to low molecular weight coal fractions, which could be used as a feed stock for the production of commodity chemicals, biopulping and biobleaching in paper industries and enzymatic polymerization in polymer industries.

Lignocellulosic biomass represents perhaps the most abundant renewable resource with a potential to replace fossilbased feedstock for sustainable energy, chemical and materials production. Among the three chief lignocellulosic biomass components (i.e. cellulose, hemicellulose and lignin), lignin is a macromolecule with an aromatic skeleton with a variety of functional groups (e.g. hydroxyl, methoxy, carbonyl, double bond) and carries a higher energy density. The unique structure makes lignin an intriguing substrate for energy, chemicals and materials productions. However, the high molecular weight and complex macromolecular structure have made lignin a challenging substrate to be transformed by many conversion methods. Microbial enzyme degradation and modification of lignin have been subjected to a significant amount research in the last a few decades. Yet so far little success has been demonstrated to merit the use of enzymatic technology for lignin transformation at a commercial scale. This paper provides an updated review of the development of lignin degrading/modifying enzymes with an emphasis on identifying the key barriers and challenges toward practical applications of microbial enzymes for lignin valorization with a hope to generate new insights and direction that can overcome these challenges.
