Properties of lipases, which not only hydrolyze lipids in aqueous solutions, but are also active in nonaqueous systems, have attracted interest of many researchers. The presented dissertation contains a review of publications devoted to synthesis and classification of microbial lipases, both intra- and extracellular ones. Types of reactions catalyzed by these enzymes, their specificity, mechanism of reaction, molecular background of the interfacial activation, and an influence of the reaction medium on their properties are discussed.
