The lipase of Rhizopus origin has been used in immobilized enzyme form
for hydrolysis and transesterification of triglycerides. The hydrolyt
ic and transesterification activities of the enzyme fixed on Doulite E
S 568, celite, cyclodextrin polymer, diatomaceous silica carriers were
determined. The fatty acid composition of bioconversion products has
been analyzed with Chrom 5 gas chromatograph and with Beckman HPLC app
aratus. The multiple use of the immobilized enzyme is highly economica
l. Keeping the optimal temperature, pH value and reaction time, the mo
dification of triglycerides becomes a controllable biotechnological pr
ocedure.
