Immobilized lipase (triacylglycerol ester hydrolase, EC 3.1.1.3) fromCandida rugosa has been immobilized on commercially available microporous polypropylene and used for the batch hydrolysis of different animal
fats. The effect of the reaction products at concentrations similar to those obtained at 90% hydrolysis, both on soluble and
immobilized lipase, was studied. Glycerol showed low inhibitory effect but oleic acid caused 50% inhibition. A mixture of
free fatty acids present in the complete hydrolysis of beef tallow inhibited lipase activity more than 70%. The stability
of the enzyme (both soluble and immobilized) was highest in the presence of 20% isooctane. The apparent Michaelis constant
for each substrate for the soluble enzyme did not change on immobilization. 相似文献

It is shown that the projection of the angular momentum of a circularly polarized electromagnetic evanescent wave along the mean velocity of energy transport (= helicity) can be reverted by a Lorentz transformation, in spite of the fact that this velocity is c. 相似文献

We compare different solutions of the convection–diffusion–reaction problem with Danckwerts boundary conditions. Analytical solution is found, and method of lines and Crank–Nicholson method are described, applied, and compared for different values of Péclet and Damköhler numbers. The eigenvalues and eigenfunctions have been obtained for all the possible values of the dimensionless parameters. And the analytical expression of the concentration has been calculated with the optimum number of terms in the Fourier expansion. 相似文献
