Pearson correlation matrix between the reactors final performances and the microbial communities of the inocula and the final community of the reactors. The asterisk shows that the correlation has a statistical significance (p < 0.05). References: H₂, consumed H₂ (in gCOD); CH₄, produced CH₄ (in gCOD); VFA, produced VFA (in gCOD)
