Sophorose, a disaccharide within sophorolipids synthesized by yeast, functions as a biosurfactant owing to its hydrophobic properties. It demonstrates multifaceted biological activities, including antibacterial, antifungal, spermicidal, virucidal, and anticancer effects. Furthermore, sophorose serves as a potent inducer of cellulase gene expression in Trichoderma reesei during fermentation.
