Shewanella
sp. strain ANA-3.
Strain ANA-3 was originally isolated from a wooden pier within a brackish estuarine
environment at Woods Hole, MA, and it is characterized by a unique As(V) respiratory
metabolism and a remarkable salinity tolerance range (Saltikov et al. 2003).
Further, ANA-3 grows faster and at higher temperatures (37 C) than many other
Shewanella species, including S. oneidensis MR-1, however, it does not grow
with DMSO as terminal electron acceptor, as most Shewanella species do. Therefore,
its sequencing would offer insight into interesting physiological adaptation
strategies, including adaptations to fluctuating salt concentrations, and contribute
to the better coverage of the phylogenetic sequence continuum that we seek
to achieve, i.e., it represents a unique cluster in the 16S rRNA gene tree,
while physiological data further support that it is a different organism from
its close neighbors also proposed for sequencing.
