Multiphase study of denials gram bacteria atypical of Antarctic origin
Listed in NASA Earthdata CMR
Three strains of psychrotrophic bacteria isolated from Antarctic coastal marine environments were studied to determine their taxonomic position.
Description
These bacteria were gram negative rods, facultatively anaerobic, and motile by means of a single polar flagellum. None of the bacterial isolates had an Na+ requirement.
Only one of the strains was capable of producing H2S from thiosulfate (S203-2). DNA-DNA hybridization experiments showed that the isolates formed two related groups clearly different from Shewanella putrefaciens. Their DNA base content was 42 and 38 mol% G+C respectively.

The fatty acid profiles of the bacterial isolates were found to be similar to the profiles of other Shewanella species. A1l of the strains contained (both) ubiquinones and menaquinones as occur with members of the genus Shewanella. Methylmenaquinones were also found. 16S rRNA gene anaIysis confirmed that isolated strains belonged to the genus Shewanella and were phylogenetically related to the newly identified Shewanella frigidimarina (99.5 % sequence similarity).
The results of the polyphasic taxonomic study allowed the conclusion that the three isolates must be classified within the genus Shewanella.
