Abstract
Lipases A and B from C.rugosa have been chemically modified with octan oyl chloride or polyethylene glycol (molecular weight: 750 or 5000). A lthough the hydrolytic activity was diminished, modification gave rise in some cases to preparations with increased synthetic activity in he xane. Furthermore, PEG(5000)-lipases A and B were significantly more s table (up to 20-fold) at alkaline pH values than the native enzymes.
