Fig. 4

Principal coordinate plot of the 16S metagenomics data of the microbial species in the fermentation cultures on the cathodic and anodic sides of the bioelectrochemical system (BES), non-bioelectrochemical system (NBES), second-stage methane fermenters (MFs) (← BES and ← NBES), and single-stage MF. The numbers indicate the hydraulic retention time (HRT) and pH of the substrate (pHin) in the first stage for the two-stage process as follows: 1: 4 days and 6.5, 2: 2 days and 6.5, and 3: 2 days and 7.3
