Background Parvularcula bermudensis (strain ATCC BAA-594 / HTCC2503 / KCTC 12087) is an obligately aerobic, NaCl-requiring, chemoheterotrophic Gram-negative bacterium isolated from the Bermuda Atlantic Time Series Station in the western Sargasso Sea, Atlantic Ocean. The cells are weakly motile short rods (sometimes coccoid), 0.4-1.3 um in diameter and 0.6-1.8 um in length, that divided by binary fission. It has a short flagellum with a mean length of 2.4 um and a hook is clearly visible at one end of flagella detached from cells. The colonies on marine agar are very small (0.3-0.8 mm in diameter), yellowish-brown and very hard . The temperature range for growth is 10-37 degrees Celsius, with optimum growth at 30 degrees Celsius. No growth is observed at 4 or 44 degrees Celsius. Extended incubation of up to 40 days is required at 10 degrees before growth is observed. The pH range for growth is 6.0-9.0, with optimum growth at pH 8.0. No growth is detected at pH 5.5 or 9.5. P. bermudensis is moderately halophilic and shows good growth at NaCl concentrations of 0.75-25% (w/v) and optimal growth at 3.0% (w/v). It produced carotenoid pigments with spectral absorbance peaks at 321 and 465 nm, but no bacteriochlorophyll a. P. bermudensis reduces nitrate to nitrite, but not nitrite to N2, and utilizes some pentoses, hexoses, sugar alcohols, oligosaccharides and amino acids as sole carbon sources, but C1-C4 compounds and organic acids are not utilized as sole carbon sources. It is susceptible to chloramphenicol, carbenicillin, tetracycline, streptomycin, puromycin, erythromycin and rifampicin. However, it is resistant to nalidixic acid, kanamycin, vancomycin, ampicillin, benzylpenicillin, gentamicin and cycloheximide. (Adapted from PMID: 12892122). (EBI Integr8)
