Summary
This comprehensive review explores how scientists can use modern genetic engineering tools to improve filamentous fungi (molds and mushrooms) for producing valuable products like antibiotics, enzymes, and sustainable food and materials. The authors explain that while these fungi naturally excel at breaking down plant material and producing useful compounds, they haven’t received as much attention from genetic engineers as other microorganisms. By applying techniques like CRISPR gene editing, computational modeling, and directed evolution, researchers can make fungal strains grow faster, produce higher yields, and use cheaper feedstocks, making industrial production more efficient and environmentally friendly.
Background
Filamentous fungi play critical roles in carbon and nutrient cycling and have been exploited for industrial applications including enzyme production, antibiotic discovery, and biomass generation. Despite their ecological and biotechnological importance, filamentous fungi have been historically overlooked by synthetic biologists compared to model organisms like bacteria and yeast.
Objective
This review summarizes synthetic biology and computational tools for mining, engineering, and optimizing filamentous fungi as bioproduction chassis. The authors detail methods to address strain development bottlenecks including slow growth rates, low production yields, and difficulties in downstream purification.
Results
The paper presents a comprehensive toolkit for fungal synthetic biology including modular cloning strategies, CRISPR/Cas genome editing, transposon-based mutagenesis, and genome-scale metabolic modeling. Examples demonstrate improvements in enzyme production, secondary metabolite discovery, and optimization of protein secretion pathways.
Conclusion
Bringing synthetic biology practices into filamentous fungi research will expand the limited panel of host organisms for commercially-feasible and environmentally-sustainable bioproduction of enzymes, chemicals, therapeutics, foods, and materials. The convergence of synthetic biology and mycobiology may catalyze the next revolution in the bioeconomy.
