Biosurfactants, recognized as eco-friendly alternatives to synthetic surfactants, offer versatile applications across industries due to their biodegradability, low toxicity, and surface-active properties. Despite having number of applications and advantages, commercialization remains difficult primarily due to the high cost, with substrates alone contributing over 50% of the total production cost. Leveraging waste as a feedstock for production has opened new avenues by reducing production costs by 10%-30% while simultaneously promoting environmental sustainability. Waste-derived biosurfactants not only offer significant cost reductions and yield (1 g/L-60 g/L depending on feedstock and strain) and environmental advantages over conventional substrates but also advance circular bioeconomy principles by transforming waste into valuable products and aiding in waste management. This review synthesizes current advancements in biosurfactant classification, microbial sources, and fermentation strategies, with a particular emphasis on the valorization of low-cost waste feedstocks, such as food processing byproducts, lignocellulosic agricultural residues, and industrial effluents.

Pearson correlation coefficients between hub immune cell populations and candidate genes were computed using the cor() function in R. Seven types of differentially abundant immune cells were identified between the two groups.

Following PPI analysis, five hub genes (CXCL8, EEF1A1, IL1B, EEF2, and IL6) were obtained. The diagnostic model demonstrated excellent performance.

This study aims to clarify LJF's molecular mechanisms in treating RA. Active components and targets of LJF and RA were determined using databases such as TCMSP, GeneCards, and OMIM. Protein-protein interaction (PPI) network analysis and pathway enrichment analysis (via KEGG as well as GO databases) were conducted to predict potential targets and pathways. Molecular docking identified potential targets of three specific LJF components. The anti-arthritic effects of LJF were evaluated in vivo using a collagen-induced arthritis (CIA) rat model. Seventeen active LJF components and 126 potential anti-RA targets were identified. Key compounds include quercetin, luteolin, kaempferol, beta-carotene, and beta-sitosterol. Main targets are AKT1, TP53, JUN, TNF, IL6, CASP3, EGFR, RELA, IL1B, and VEGFA. KEGG analysis suggested the involvement of the PI3K-AKT, TNF, and IL-17 pathways. Molecular docking demonstrated that β-sitosterol, quercetin, and luteolin effectively bind to AKT1, IL6, JUN, TNF, and TP53. In vivo studies confirmed that LJF reduces pathological damage and inflammatory markers (TNF-α and IL-6) in a dose-dependent manner, supporting its anti-RA effects via AKT and RELA through PI3K-AKT and NF-κB pathways. This research identified the PI3K-AKT and NF-κB signaling pathways as key targets of LJF, highlighting their roles in its anti-RA effects.
