Biomass recalcitrance, the resistance of plants to release their sugars for biofuel production, is a major obstacle to the development of a sustainable bioeconomy. Overcoming this challenge necessitates a comprehensive, multidisciplinary approach. By investigating the chemical, structural, and physical properties of biomass, researchers gained a deeper understanding of recalcitrance. This knowledge enabled the manipulation of plant cell wall composition and the development of improved enzymes and microorganisms for efficient biomass deconstruction. However, there are still many unknowns that need to be addressed.
Genome editing technologies offer promising avenues for overcoming biomass recalcitrance. By precisely modifying plant genomes, researchers can engineer crops with reduced lignin content, altered cell wall structures, or enhanced sugar release. Techniques like CRISPR-Cas9 allow for targeted modifications of genes involved in cell wall biosynthesis, enabling the creation of plant varieties with increased susceptibility to enzymatic breakdown. Furthermore, genome editing can be used to introduce genes from microorganisms that possess enzymes capable of deconstructing recalcitrant biomass, thereby enhancing the plant's intrinsic ability to release sugars for biofuel production. Here, we present our current knowledge and research gaps for overcoming and understanding biomass recalcitrance.
