MICROBIOLOGICAL COMPLEX FOR MODELING PROCESSES IN THE GASTROINTESTINAL TRACT OF ANIMALS

In vivo modeling of digestive processes is not a standard mathematical modeling task, taking advanced technologies of several sciences. This article will consider a microbiological complex for modeling the processes occurring in the gastrointestinal tract of animals. The system belongs to mini-models with a working volume of up to 400 ml, the simulation of the dynamics of the mixing of the chyme is static, which significantly simplifies the methodology of conducting experiments, but imposes difficulties on the stages of pretreatment of food matrices. The following characteristics are achieved: reactor volume from 50 to 100 mL; a pH accuracy of ± 0.1; temperature accuracy of ± 0.063 °C.
