摘要：

The activity and enantioselectivity of Lipase PS from Pseudomonas cepacia and lipoprotein lipase from Pseudomonas sp. were investigated in organic solvents preequilibrated to water activities ranging from <0.1 to 0.53, using as a model reaction the transesterification between (+/-)-sulcatol and vinyl acetate. Variations of water activity markedly influenced the transesterification rate but did not modify the enantioselectivity of the two enzymes.
