Bathyarchaeota, formerly known as the Miscellaneous Crenarchaeotal Group, is a phylum of global generalists that are widespread in anoxic sediments, which host relatively high abundant archaeal communities. The 16S rRNA gene based tree was generated using 16S rRNA gene sequences derived from selected archaeal representatives publically available in the SILVA database. Hence, the supply of anaerobic digesters converting crop material with trace elements is crucial [43]. Investigations of the biogeochemical roles of benthic Archaea in marine sediments are hampered by the scarcity of cultured representatives. However, the reconstruction of the metabolic pathways suggests that the analyzed Bathyarchaeota may base their metabolisms on carbohydrates and amino acids utilization as well as on CO2 fixation. As expected, these results support the importance of Firmicutes for anaerobic cellulolysis/hydrolysis, acidogenesis, and acetogenesis at mesophilic and thermophilic temperatures.
