High conversion yields of
68% have also been reported in the case of synthesis
of ascorbyl-palmitate by Candida antartica lipase
[20]. No esterification with lower chain fatty acids
was observed except with butyric acid (conversion
yield 56.3%). In contrast to data in Tables 3 and 4
where esters with oleic acid were not formed, reversal
in substrate specificities were observed as regards
short chain fatty acids excepting butyric acid when
ascorbic acid was used as the substrate (Table 5).
This variation is well known for lipases which vary
markedly in their substrate specificities with a change
in one of the substrates and the reaction system
[3,15,16].
It can be concluded that lipase production by A.
terreus is affected by the type of oil, pH and nitrogen
source in a growth-dependent manner and by Ca2
and Mg2 in a growth-independent manner. This lipase
is able to carry out esterification reacti
