Solid-State Fermentation for the Recovery of Phenolic Compounds from Agro-Wastes

The review article explores solid-state fermentation (SSF) as an eco-friendly method for extracting phenolic compounds from agro-wastes, which are typically considered pollutants. SSF is advantageous due to its low water usage, minimal equipment needs, and reduced wastewater production, making it a sustainable alternative to traditional methods. The document highlights the health benefits of phenolic compounds, such as antioxidant, antimicrobial, and anticancer properties, and their potential against SARS-CoV-2. It discusses the roles of microorganisms like Aspergillus species in enhancing polyphenol recovery and emphasizes the importance of optimizing factors like inoculum, moisture, and pH. The review underscores the potential of using agro-wastes like Castilla rose, mango, grapes, and pomegranate in SSF to create value-added products with health and industrial applications.
