Croceibacter atlanticus HTCC2559

Croceibacter atlanticus HTCC2559T was cultivated from seawater collected at a depth of 250 m from the Sargasso Sea and was isolated by high throughput dilution-to-extinction culturing. It is a bright saffron-colored, strictly aerobic, obligate chemoheterotroph. Cells are non-motile straight rods, about 1.9 um long and 0.4 um wide, dividing by binary fission. Temperature range for growth is 10 - 28 degrees C, with optimum growth at 20 - 23 degrees C with no growth observed at 4 and 30 degrees C. The pH range for growth is pH 6.0 - 10.0, with optimum growth at pH 7.5 - 8.0. It is moderately halophilic, showing good growth at NaCl concentrations of 0.5 - 15% (w/v), with optimal growth at 3.0% (w/v) NaCl. As suggested by it color, it produces carotenoid pigments with wavelength absorbance spectral peaks at 318 and 483 nm. There was no difference in the spectral peaks between light-grown and dark-grown cultures. It degrades gelatin, DNA, starch, casein, and elastin, but not cellulose (adapted from PMID 12747413 and 20639333). (EBI Integr8)
