Abstract:
The nucleotide sequence of 5 S ribosomal RNA (rRNA) of type strain Sulfobacillus thermosulfidooxidans VKM B-1269 was determined. This organism represents a group of moderately thermophilic acidophilic chemolithotrophic bacteria, able to use ferrous and sulfur compounds as the sole energy source. 5 S rRNA of this bacterium is drastically different from all other known bacterial 5 S rRNA sequences. It is suggested that S. thermosulfidooxidans represents a new lineage of bacterial evolution, that diverged from other bacteria at an early step of their evolution.
