| Abstract: | The Hopf bifurcation of solutions to a system of ordinary differential equations on micro-organisms continuous cultivation is studied. The mian results of the paper are using bifurcation theory which is studied for the bifurcation of a kind delay differential equation as parameter by the time lag. |
