Optimization of functional polysaccharide production in Naematelia aurantialba : Surfactant‐driven yield enhancement and multifunctional property optimization

This study establishes an effective T80 supplementation strategy to enhance NAPS yield and functionality in submerged fermentation, and further elucidates its mode of action as a metabolic regulator. These findings offer a sustainable method for generating NAPS and lay the groundwork for utilizing surfactants to boost yields of edible and medicinal fungal polysaccharides. This approach shortens the fermentation duration by 12 h, substantially reducing energy consumption and operational costs, offering an environmentally friendly and economically viable strategy for industrial-scale polysaccharide production. © 2026 Society of Chemical Industry.
