Complete genome sequence of Methanoculleus bourgensis strain MAB1 the syntrophic partner of mesophilic acetate-oxidising bacteria (SAOB)

摘要

Methanoculleus bourgensis strain MAB1 has been identified as the hydrogenotrophic partner of mesophilic acetate-oxidising bacteria, a syntrophic relationship operating close to the thermodynamic equilibrium and of considerable importance in ammonia-rich engineered biogas processes. Methanoculleus bourgensis strain MAB1 belongs to the order Methanomicrobiales, family Methanomicrobiaceae, within the phylum Euryarchaeota. The genome shows a total size of 2,859,299 bp encoding 3450 predicted protein-encoding genes, of which only 1472 (43 %) have been assigned tentative functions. The genome encodes further 44 tRNA genes and three rRNA genes (5S, 16S and 23S rRNA). This study presents assembling and annotation features as well as genomic traits related to ammonia tolerance and methanogenesis.Electronic supplementary materialThe online version of this article (doi:10.1186/s40793-016-0199-x) contains supplementary material, which is available to authorized users.
