Resumen

To reduce the energy and operational demands associated with lignocellulosic biomass deconstruction to produce biofuels and high value-added products, a range of innovative strategies has gained increasing attention within biorefinery systems. Among these, oxidative approaches employing enzymes and methods assisted by hydrodynamic phenomena have emerged as particularly promising. In parallel, the use of additives at different processing stages, including pretreatment and enzymatic hydrolysis, has proven critical for enhancing biomass digestibility and increasing the yield of fermentable compounds. This review critically examines alternative booster strategies, namely oxidative enzymes, hydrodynamic cavitation, and surfactants, through a systematic analysis of the fundamental mechanisms governing biomass deconstruction. Furthermore, recent technological advances are highlighted, and the mechanistic interplay and synergistic effects among these strategies are discussed, providing insights into their integrated application for the optimization of lignocellulosic biomass processing within a biorefinery framework.
