Article Synopsis
- Basidiomycete white rot fungi play a crucial role in the global carbon cycle by degrading all components of plant cell walls.
- The study examined the proteomes of two similar white rot fungi grown on spruce wood, revealing that about 5% of their proteins are enzymes specifically for breaking down plant cell walls.
- Differences in enzyme production rates were linked to the initial growth rates on the wood, providing insights for potential biotechnological uses of these fungi and their enzymes.
Production of value-added compounds from a renewable aromatic polymer, lignin, has proven to be challenging. Chemical procedures, involving harsh reaction conditions, are costly and often result in nonselective degradation of lignin linkages. Therefore, enzymatic catalysis with selective cleavage of lignin bonds provides a sustainable option for lignin valorization.

- The white-rot fungus Obba rivulosa efficiently breaks down softwood by selectively removing lignin from spruce wood, which has potential applications in the pulp and paper industry.
- A study focused on the monokaryotic strain 3A-2 revealed how the fungus changes its gene expression over an 8-week period during solid state cultivation.
- Initial high expression of genes for degrading plant cell walls was observed at the 2-week mark, followed by a decrease, indicating that different fungal strains may have varying abilities to degrade plant materials.
The biological conversion of plant lignocellulose plays an essential role not only in carbon cycling in terrestrial ecosystems but also is an important part of the production of second generation biofuels and biochemicals. The presence of the recalcitrant aromatic polymer lignin is one of the major obstacles in the biofuel/biochemical production process and therefore microbial degradation of lignin is receiving a great deal of attention. Fungi are the main degraders of plant biomass, and in particular the basidiomycete white rot fungi are of major importance in converting plant aromatics due to their ability to degrade lignin.
