**Morphological, physiological, and biochemical characteristics**  Cells were non-motile and not observed to form spores or possess flagella, though over 30 flagella or flagella-associated genes are present in the genome. In contrast, the genome for a non-motile close relative (_P. cryptus_) does not contain any flagellar genes so it is possible that strain Coronado(T) is motile under specific conditions. Unlike most members of the _Erythrobacteraceae family_, strain Coronado(T) is oxidaseand catalase  negative. This strain is also catalase positive, and  unable to hydrolze casein or starch. Cells were oval or rod shaped and ranged in length from 1.2um to 2.2um with an average of 1.6um (Figure 1). Cell width ranged from .6um to 1um with an average of .8um.  Growth was only observed under aerobic conditions, from 4°C 4°C  to 28°C, 28°C,  with optimal growth around 25°C. 25°C.  Low levels of growth were observed at pH 6.0 up to pH 8.0, maximum growth occured around neutral pH. Salt was required for growth, and the strain could not grow at >1.5% NaCl, optimal growth was at .5% NaCl. Strain Coronado(T) could utilize the following as sole carbon sources: Glycyl-L-Glutamic Acid, L-Rhamnose, D-Mannose, D-Trehalose, a-D-Glucose, L-Fucose, D-Galactose, Citric acid, D-Glucuronic acid, D-Galactonic acid, L-Galactonic acid-\(\gamma\)-Lactone, Acetoacetic acid, Acetic acid, Pyruvic acid, and L-Malic acid.
