Synthesis of Terpene Alcohol Esters by Lipase

Enzymatic synthesis of geraniol and citronellol esters by direct esterification in n-hexane

“…Palatase exhibited higher efficiency for increasing fatty acid chain length with an optimum around butyric and caproic acids. This is in agreement with earlier findings (Iwai et a/.,1980;Langrand ef al., 1990). Lipases from M. miehei on the other hand showed an increasing affinity for longer chain fatty acids.…”

Novel bacterial isolates for the resolution of esters of tertiary alcohols

“…Since both enantiomers differ in odor (Ohloff and Klein, 1962) their availability in optically pure form is desirable for flavor and fragrance composition. (+)-Linalool was reported to be a non-substrate for several microbial lipases in esterification reactions (Iwai et al, 1980;Okumura et aL, 1979). The corresponding acetate, however, could be hydrolyzed with varying success using whole microbial cells.…”

Production and characterization of extracellular lipase from Calvatia gigantea

“…Research on lipase production has been intensified in recent years due to the potential of this enzyme to both hydrolyse fats and synthesize specific esters with desirable flavour properties for industrial application (Macrae and H a m m o n d 1985;Langrand et al 1990). Whereas several publications on lipase properties have appeared so far (Iwai et al 1980;Nishio et al 1987;Langrand et al 1990) relatively little information is available on production processes of the enzyme (Nair and Bone 1987;Valero et al 1988).…”
