1Improvement of Properties of Pseudomonas sp.Lipase in Resolution of 2-Octanol显示文摘A novel preparation method was developed to form a surfactant-lipase complex for the resolution of 2-octanol in a solvent-free system. The E value was improved from 6.64 to 120.2. The lipase modified by the anionic surfactant possessed a low solubility in the solvent-free system, which was beneficial to the recovery and the repeated usage of the lipase. The surfactant-lipase complex maintained a high enantioselectivity after five cycles of usage. The effect of water on both the activity and the enantioselectivity of the lipase has also been investigated; the direct addition of a salt hydrate pair of Na 4P 2O 7·H 2O and Na 4P 2O 7 can dramatically activate the modified enzyme.WANGZhi QUANJing WENGLiang ZHENGLiang-yu LIUNing DONGHuan CAOShu-gui 2003Chemical Research in Chinese Universities2003,19,4:3
2Resolution of 2-Octanol via Lipase-catalyzed Enantioselective Acetylation in Organic Solvents显示文摘The lipases from different sources were screened for their ability to catalyze the resolution of 2-octanol in organic solvents with vinyl acetate as the acylating reagent. The medium effect has been studied on the irreversible transesterification with varying water activity(a_w). The influence of vinyl acetate concentration on it has also been investigated. Under the optimal conditions, the enantiomeric ratio(E value) of pseudomonas fluorescence lipase(PFL) exceeded 200 with an enantiomeric excess(e.e.) of S-2-octanol above 99% at a 51% degree of conversion.WANGZhi LIZheng-qiang YuDa-hai WENGLiang LIUMing ZHANGGui-rong CAOShu-gui 2004Chemical Research in Chinese Universities2004,20,5:1
