Aspergillus Hydrophobins: Physicochemical Properties, Biochemical Properties, and Functions in Solid Polymer Degradation

Takumi Tanaka et al.

Summary: In this review, the properties and functions of Aspergillus hydrophobins are comprehensively discussed based on recent findings. Aspergillus hydrophobins can be purified in a water phase without organic solvents and self-assemble to form amphipathic membranes. Certain hydrophobins help Aspergillus evade host immune recognition and recruit cutinases for polyester hydrolysis. Aspergilli produce various small secreted proteins (SSPs) to decompose solid polymers.

Systems biology-guided understanding of white-rot fungi for biotechnological applications: A review

Teeratas Kijpornyongpan et al.

Summary: Plant-derived biomass is a rich carbon source on Earth, and white-rot fungi have the unique ability to efficiently break down plant cell walls. They play a crucial role in global carbon cycling and have potential applications in biotechnology. Current research on white-rot fungi has mainly focused on their extracellular enzymes, while their intracellular metabolism remains less explored. Systems biology is a powerful tool to study the biological processes of white-rot fungi.

Comparative transcriptional analyses of Pleurotus ostreatus mutants on beech wood and rice straw shed light on substrate-biased gene regulation

Hongli Wu et al.

Summary: P. ostreatus expressed variable enzymatic repertoire-related genes in response to distinct substrates; a demand to upregulate cellulolytic genes seems to be present in ligninolysis-deficient mutants; the regulation of some specific genes probably driven by the demand is dependent on the substrate.

Targeted disruption of hir1 alters the transcriptional expression pattern of putative lignocellulolytic genes in the white-rot fungus Pleurotus ostreatus

Hongli Wu et al.

Summary: Mutational analysis of a mutant with decreased lignin-degrading ability in P. ostreatus revealed that a mutation in the hir1 gene encoding a histone chaperone altered the expression pattern of ligninolytic genes. This suggests that hir1 plays a critical role in regulating lignocellulolytic genes in P. ostreatus.

Intracellular pathways for lignin catabolism in white-rot fungi

Carlos del Cerro et al.

Summary: Research shows that two white-rot fungi can utilize lignin as a carbon source and funnel carbon from lignin-derived aromatic compounds into central carbon metabolism via intracellular catabolic pathways. These insights into global carbon cycling and the foundation for a sustainable bioeconomy highlight the importance of simultaneous lignin depolymerization and bioconversion by white-rot fungi.

Efficient genome editing with CRISPR/Cas9 in Pleurotus ostreatus

Tatpong Boontawon et al.

Summary: Efficient gene mutagenesis in Pleurotus ostreatus was achieved using plasmid-based CRISPR/Cas9, generating drug-resistant strains and introducing mutations via homology-directed repair. This approach could contribute to molecular breeding of non-GM cultivated strains in the future.
