摘要

Lignocellulose, one of the world's most abundant renewable resources, is essential to produce animal feeds, biofuels, and other valuable products. However, its complex and resilient structure poses a significant challenge to the conversion process. White-rot fungi (WRF), nature's primary lignin degraders, are emerging as a powerful biological tool to unlock the full potential of this valuable resource. A bibliometric analysis of research conducted between 2003 and 2024 indicates a consistent rise in global publication output concerning WRF-based lignocellulose degradation. The analysis identifies clear research hotspots in four main areas: (1) selection and optimization of fungal strains, (2) elucidation of enzyme-driven degradation pathways, (3) development of effective pretreatment strategies, and (4) innovation in applied products, especially high-quality feed ingredients. Furthermore, network mapping reveals that cross-border collaborations significantly amplify research influence and visibility. In the future, greater attention should be paid to targeted enzyme engineering to enhance catalytic efficiency, expanded exploration of multifunctional products—particularly feed additives with nutritional and bioactive properties—and scaling up processes from pilot studies to industrial-scale operations.
