✦ Synopsis

Cundida antarctica lipase was investigated for the synthesis of short chain fatty acid esters of geraniol in a solvent-free system. Maximal activity occurred at 60°C. High yields (about, 100%) were obtained with propionate and butyrate, while acetate showed much lower reactivity. The enzyme was used in four consecutive batch reactions with only a 10% loss of activity.
