Phylogenetic Analysis of Aquaspirillum magnetotacticum Using Polymerase Chain Reaction-Amplified 16S rRNA-Specific DNA

Abstract

The 16S rRNA gene of the magnetotactic magnetogen Aquaspirillum magnetotacticum MS1 was amplified by a polymerase chain reaction, using two eubacterial consensus oligodeoxynucleotide primers flanking the majority of the 16S rRNA gene, cloned, and sequenced. Phylogenetic analysis revealed that A. magnetotacticum MS1 belongs to the alpha-group of proteobacteria. This assignment offers perspective on the biochemical properties of A. magnetotacticum, since this organism is expected to have the general properties that are common to this phylogenetic group.
