Stolz et al. 1999.
Gram-negative, vibrioid to spiral-shaped cells, 0.3 x 1-2 μm. Motile by polar flagella.
Isolated from enrichments using agar plates containing a minimal salts medium with
20 mM acetate and 20 mM selenate, incubated in the presence of hydrogen. Grows at
25-35 ºC, but not at 42 ºC. Grows in the presence of 0.05% NaCl and pH 7.5. May
grow in microaerobic conditions.
Isolated from a selenium-contaminated freshwater marsh, Nevada, USA.
Undetermined.

Can utilize selenate and arsenate as electron acceptors. Selenate is reduced through
selenite to selenium. Nitrate is reduced to ammonium. Selenate, arsenate,
thiosulfate,
S0, trimethylamine oxide, Fe(III), nitrate, fumarate, aspartate & manganese
dioxide can
be used as a terminal electron acceptor when grown under anoxic
conditions with
lactate as the electron donor. Ferments fumarate.
