Recent advances in production of lignocellulolytic enzymes by solid-state fermentation of agro-industrial wastes

Agricultural, forestry, and food industries produce large amounts of lignocellulosic wastes every year. Land disposal of these residues without proper treatment leads to environmental pollution and negative health effects. The recent advances in valorization of agro-industrial wastes by the production of lignocellulolytic enzymes under solid-state fermentation (SSF) are reviewed. SSF is a promising technology to produce lignocellulolytic enzymes. However, the large-scale feasibility is the main challenge of SSF being the control of operational parameters and adequate reactor design the first locks. The current and future trends of SSF bioreactors for lignocellulolytic enzyme production are summarized. SSF allows the production of lignocellulolytic enzymes with high stability at different temperatures and pH, improving their applicability in different industrial settings.

Automated summary

The agricultural, forestry, and food industries produce large amounts of lignocellulosic wastes annually, requiring proper treatment to prevent environmental pollution and negative health effects. Recent advancements in solid-state fermentation (SSF) for producing lignocellulolytic enzymes show promise, but face challenges in large-scale feasibility. Control of operational parameters and adequate reactor design are key obstacles to overcome in utilizing SSF for lignocellulolytic enzyme production.
