Canonical correspondence analysis (CCA) ordination diplot for the archaeal community. Red vectors represent the influence of the process parameters such as pH (pH), organic loading rate (OLR), biogas production (Biogas), total solids (TS), volatile solids (VS), methane (CH4), carbon dioxide (CO2) and hydrogen sulphide (H2S) contents in the biogas, alkalinity (Alk.), ammonium–nitrogen (NH4–N), total volatile fatty acids (Total VFAs), acetate (Acet.) and propionate (Propio.), contents in the sludge; blue triangles represent archaeal taxa derived from the high-throughput 16S rRNA amplicon sequencing at the species level: unknown Methanomassiliicoccaceae (U.Mmass.), unknown Methanospirillaceae (U.Mspir.), unknown WSA2 (U.WSA2.), unknown vadinCA11 (U.vadin.), Methanobacterium sp. A (Meth.A.), Methanobacterium sp. B (Meth.B.), Methanoculleus sp. (Mcul.), Methanomassiliicoccus sp. (Mliico.), Methanomethylovorans sp. (Mmethyl.), Methanosaeta sp. (Msae.), Methanosarcina sp. (Msar.), unknown pGrfC26 A (U.pGrf.A), unknown pGrfC26 sp. B (U.pGrf.B). A detailed correlation matrix including all process parameters and the archaeal community diversity is provided as Additional file 2: Table S4
