Figure 1. Overview of batch fermentation and PolyFermS experiments. IR with immobilized Kenyan infant fecal microbiota and connected PolyFermS second-stage treatment reactors (TR1-6). Each fecal microbiota was immobilized and cultivated separately. (A) IR microbiota of donors 1 to 3 were used for batch fermentations in 24-well plates, and (B) IR of donors 4 and 5 were connected to TRs. IR: Inoculum reactors; TRs: test reactors; qPCR: quantitative PCR; HPLC: high-performance liquid chromatography; T: temperature; RT: retention time; STAB: stabilization period; TREAT: treatment period.
