Brown %J Atlas Journal of Biology %D 2010 %I Atlas Publishing, LP %X The diversity of Archaea in a municipal wastewater sludge sample was investigated by amplification of ribosomal RNA genes from sludge DNA using archaeal-specific primers. Surprisingly, a large fraction (32%) of these sequences were from Halobacteriales, not previously seen in surveys of wastewater sludge. Other abundant sequences were from members of uncultivated ¡®environmental¡¯ archaeal groups that are commonly detected in sludge and sediment environments. Only a few distant relatives of Methanosarcina (which are commonly thought of as the predominant methanogenic species in sludge environments) were detected. %K Archaea %K methanogen %K halophile %K Euryarchaea %K Crenarchaea. %U http://www.atlas-publishing.org/table_of_content.php?tablecontentid=55&action=download&
