Abstract
The 16S rRNA of the bacterion Aquifex pyrophilus, a microaerophilic, oxygen-reducing hyperthermophile, has been sequenced directly from the the PCR amplified gene. Phylogenetic analyses show the Aq. pyrophilus lineage to be probably the deepest (earliest) in the (eu)bacterial tree. The addition of this deep branching to the bacterial tree further supports the argument that the Bacteria are of thermophilic ancestry.Entities:
