Ab. Medvinskii et al., The mechanism of formation of Liesegang structures around Dictyostelium discoideum population, BIOFIZIKA, 45(3), 2000, pp. 525-531
A theoretical study of the: phenomenon of Liesegang structure formation ind
uced by the Dictyostelium discoideum population in a medium containing foli
c acid was carried out. Using a "reaction-diffusion" model proposed in this
work, it was shown that the formation of Liesegang structures around the D
ictyostelium discoideum population depends on two competing processes: (a)
inactivation of folic acid by vegetative amoebae and (b) the chemical react
ion of folic acid with the products of amoeba metabolism, which results in
the formation of insoluble sediment. The dependence of the model solutions
on the geometric and functional parameters was studied. The results are in
good agreement with experimental data.
