英文摘要: Rhamnolipid as a biosurfactant was produced by a strain of pseudomonas sp. Cultured in a 10L stirring fermentor for 80 h. The yield of rhamnolipid was 22g/L. Rhamnolipid was hydrolyzed in 1 mol/L sulfuric acid at 120℃ for 1.5 h to obtain the highest yield of rhamnose which was over 95%. After removing lipid by organic solvent and ions by ion-exchange resin, pure rhanmose was obtained through crystallization at yield of about 70%. The chemcial structure of hydrolysis products determined by NMR and MS was rhamnose and β-hydroxydecanoic acid.
