Fig. 9From: Production, characterization, and antifungal activity of a biosurfactant produced by Rhodotorula babjevae YS3The least energy structures of the sophorolipid (SL) homologues detected during LC–MS analyses of the SL produced by Rhodotorula babjevae YS3 and SL standard, 1,4′′-sophorolactone 6′,6′′-diacetate. Structures were drawn in ChemDraw Ultra 12.0 (LS lactonic SL, AS acidic SL, Ac acetyl group)Back to article page
