The QPlus fermenter system (Sartorius) consists of three 0.5L fermenters directed by a control tower and BioPat software which analyzes all post-partum fermentation parameters. This system is mainly used to study the intestinal microbiota. We use the ImmoGut model, characterized by the immobilization of the intestinal microbiota into beads imitating the continuous liberation of bacteria from the intestinal wall to the intestinal tract.
