| Parvularcula bermudensis Cho and Giovannoni, 2003 |
Parvularcula bermudensis was identified in 2003 in the western Sargasso Sea in the Atlantic Ocean. It is a marine bacterium that forms a deep branch in the Alpha Proteobacteria, distinct from the other orders.
Parvularcula isolates are Gram-negative, strictly aerobic, chemoheterotrophic, slightly motile short rods with a single flagellum. Colonies on marine agar are very small (0·3–0·8 mm in diameter), yellowish-brown and very hard. They are oxidase positive and catalase negative.
