Sophorose (2-O-beta-D-Glucopyranosyl-D-glucopyranose) monohydrate is the disaccharide component of microbial glycolipids, which are often used as biosurfactants due to their hydrophobicity. Sophorolipids also exhibit antibacterial , antifungal , spermicidal, virucidal, and anticancer activities. In studies of Trichoderma reesei fermentation, sophorose monohydrate has been identified as a potent inducer of cellulase gene expression.
