Investigating the molecular mechanisms that control this process is essential for identifying ways to degrade and use lignocellulose, a recalcitrant waste-product residue from biofeedstocks and agricultural residues, and accelerate the development of biotechnology.
It is also essential for deepening understanding of the ecological role of fungi in the global carbon cycle. However, current research on fungal plant biomass conversion (FPBC) of agricultural residues is far from comprehensive because most studies investigate only single species. To tackle these challenges, a multi-institutional team of researchers conducted a systematic analysis of transcriptome, proteome and metabolome profiles (a multiomics approach) of five fungi grown on two common agricultural feedstocks: soybean hulls and corn stover.
Analyses revealed strong time-, substrate- and species-specific patterns in fungal gene, protein and metabolite profiles associated with plant lignocellulose conversion. These findings demonstrate that a multiomics approach can provide a deeper understanding of the complex molecular changes and diversity associated with FPBC. By linking the fungal genes, enzyme activity and metabolic pathways involved in lignocellulose degradation, the approach reveals how fungi adapt to complex plant-derived carbon sources.
The findings are published in the journal MicrobiologyOpen. This knowledge can help guide the future engineering of fungal systems for converting agricultural waste into biofuels, biochemicals and other value-added bioproducts. FPBC is important to the bioeconomy because it helps turn plant waste into fuels, chemicals and other valuable products through biological processes.
It has been increasingly applied to produce biofuels and biochemicals from lignocellulose. The team's comprehensive multiomics analysis of five fungi grown on agricultural feedstocks provides key insights into how different species adapt their metabolic and regulatory strategies to distinct substrates and environmental conditions. This improved understanding of species-specific pathways, enzymes and metabolite production enhances researchers' ability to engineer fungi for more efficient biomass deconstruction and conversion.
These advances can accelerate the development of sustainable biotechnological processes that transform agricultural waste into valuable bioproducts. A multi-institutional team of researchers led by the Westerdijk Fungal Biodiversity Institute systematically analyzed the molecular profiles over time of five fungi grown on two common agricultural feedstocks. The Environmental Molecular Sciences Laboratory (EMSL), a Department of Energy (DOE) Office of Science user facility at Pacific Northwest National Laboratory, provided advanced instrumentation for analyzing proteome and metabolome changes.
