✦ Synopsis

A kinetic model of solid state fermentation with temperature deactivation of microorganisms is presented. The experimental results of cultivation of Aspergillus niger on a mixture of wheat bran and beet pulp in temperature range from 26 ~ to 40 ~ were used to estimate the parameters of the model. The activation energies of growth, thermal deactivation and maintenance have been calculated.
