| They appear to be the most ancient ones yet seen and may resemble the nitrogen-fixing genes in the common ancestor of archaea, bacteria, and multicellular life, the researchers say in the Dec. Based on the modern phylogenetic classification, Bacteria, Archaea (microbes living in extreme environments) and Eukarya (sometimes termed Eukaryota) (66) may be recognized as the three domains for which separate mother cells had been produced from the PBC. Probe S-G-Syn-0424-a-A-18 was used along with an existing probe that targets the SSU rRNA sequences of Archaea to quantify the relative activity of syntrophic benzoate-degrading and methanogenic populations in 2-L mesocosms inoculated with sediment and amended with 3-CB, 2-CP, or no substrate. |
