Commercially useful lipases are usually obtained from microorganisms that produce a wide variety of extracellular lipases. Many lipases are active in organic solvents where they catalyze a number of useful reactions including esterification (Chowdary et al., 2001; Hamsaveni et al., 2001; Kiran et al., 2001a; Kiyota et al., 2001; Krishna and Karanth, 2001; Krishna et al., 2001; Rao and Divakar, 2001), transesterification, regioselective acylation of glycols and menthols, and synthesis of peptides (Ducret et al., 1998; Zhang et al., 2001) and other chemicals (Therisod and Klibanov, 1987; Weber et al., 1999; Born- scheuer, 2000; Berglund and Hutt, 2000; Liese et al., 2000; Azim et al., 2001).
