employed to produce biofuels. Besides converting biomass into biofuels, their
components are individually useful for the assembly of high-value-added products.
Recalcitrance caused by the material properties slows progress toward a better
and refined conversion. Genetically engineering crops is not a new process, which
means that investing and studying ways to genetically improve the biomasses
regarding their resistance to pretreatments and conversion is already a reality.
These pretreatments are also constantly being updated to offer different ways of
altering the biomass. Biomass conversion is a modern necessity and will be increasingly vital.
