Summary: This study investigates the valorisation of lignin in a biorefinery based on lignocellulosic biomass by treating technical lignin with recombinant laccase and mediator. The treatment resulted in a preferential reduction of guaiacyl units in the recovered lignin. Phenolic compounds deriving from guaiacyl or p-hydroxyphenyl units were identified in the aqueous phases, with higher concentrations observed when an ionic liquid was involved in the treatment.

Summary: Phenolic compounds (PhCs) are widely found in plants, body fluids, food items, medicines, pesticides, dyes, etc., and many of them are highly toxic, teratogenic, and carcinogenic. There is an urgent need to develop an effective tool for the analysis of PhCs to address their environmental and health concern. Carbonaceous nanomaterials have emerged as a promising material for the fabrication of electrochemical biosensors for the detection of PhCs.

Summary: In this study, five recombinant strains were selected to produce laccase isozymes with high activities for the degradation of endocrine disrupting chemicals (phenolic compounds). The specificity and efficiency of each recombinant laccase for different phenolic compounds were investigated, and optimal degradation conditions were identified. The results suggest promising perspectives for the degradation and oxidative biotransformation of typical phenolic pollutants in the environment.

Summary: Monitoring phenolic compounds is crucial in various sectors, and laccase-based biosensing platforms have proven to be effective. However, a detailed account of advancements in laccase immobilization techniques is lacking. This review evaluates the impact of nano-immobilization techniques on laccase biosensing platforms and discusses future developments, including multi-layer laccase electrodes, covalent immobilization routes, electroconductive polymeric matrices, and novel entrapment techniques. This comprehensive assessment provides insights into the feasibility of highly specific laccase biosensors for industrial, medicinal, food, and environmental applications.

Summary: This study confirms the production of various reactive oxygen species (ROS) through oxidation of phenolic acids (PCs) by laccase, which has a significant impact on the transformation of sulfamethoxazole (SMX) in soil and aquatic environments. The presence of gallic acid (GA) enhances the transformation of SMX by laccase, and the formation of ROS such as semiquinones radical (SQ(center dot-)), superoxide anion radical (O2(center dot-)), hydrogen peroxide (H2O2), hydroxyl radical (center dot OH), and singlet oxygen (O-1(2)) is confirmed. The dissolved O-2 plays a fundamental role in the formation of SQ(center dot-), which initiates chain reactions for the generation of other ROS. The transformation pathways of SMX include the breaking of S-N bond, cleavage of oxazole ring, electrophilic substitution, Michael addition, and condensation reactions. The presence of electron-withdrawing substitution groups on the benzene ring of PCs and the less stability of SQ(center dot-) are believed to favor the transformation of SMX. These results improve our understanding of the role of laccase-mediated oxidation of PCs in SMX transformation and have implications for the treatment of SMX pollution using laccase.

Summary: This study investigated the expression patterns and functionality of SmLAC25 in Salvia miltiorrhiza. The results showed that overexpression of SmLAC25 increased lignin content in plantlets and hairy roots, but decreased the concentrations of rosmarinic acid and salvianolic acid B. Further studies revealed that the overexpression of SmLAC25 promoted lignin synthesis and inhibited salvianolic acid biosynthesis.

Summary: In this study, fungal laccase from Cerrena unicolor was used as a biocatalyst for converting 8-anilino-1-naphthalenesulfonic acid into a green-coloured antibacterial compound with dual functions as an antimicrobial agent and textile dye. The optimized transformation process resulted in a crude product with low cytotoxicity, antibacterial properties, and antioxidant properties. The synthesized green compound was non-allergenic and highly efficient in dyeing wool fibers.
