The gene for ribulose-bisphosphate carboxylase was characterized for several chemoautotropic bacterial symbionts. The gene of the symbiont of the deep-sea snail Alvinochonca hessleri has been largely sequenced and compared to the sequences of other photo- and chemoautotrophic bacteria and a preliminary phylogenetic tree has been constructed. Oligonucleotide probes against the symbionts in Lyrodus pedicellatus have been used to verify the identity of this bacterium. Method development to obtain sequences from badly preserved symbiont host samples has been continued. Keywords Symbiotic bacteria Oligonucleotide probes, 16S rRNA sequences.
