5S ribosomal RNA sequences of Vibrio adaptatus, V. cyclosites, V. hollisae and V. neocistes; three of these eubacteria may not be true members of the Vibrionaceae.

To estimate the phylogenetic position of each bacterial species, ACKNOWLEDGEMENTS the nucleotide sequences of the 5S nbosomal RNAs from four Gram-negative marine eubacteria, Vibrio adaptatus, V. This work was supported in part by the following grants; NSF cyclosites, V. hoUisae and V. neocistes were determined by #BSR-8806509, EPA #CR812246 and ONR chemical and enzymatic methods (1). The 5S rRNAs of V. #N00014-86-K0696. adaptatus, V. neocistes and V. cyclosites show very low homologies (69%, 69% and 74% on average, respectively) to REFERENCES those of most other Vibrio species (2), indicating that these three i p ^ y H , Hon.H , Suzulu,K I , Osawa.s and Komagata.K (1987) J species are not true members of the Vibrionaceae.
