An organism from a goldfish aquarium, isolated on barbital medium, was found to be a Grampositive coccus which divided in alternating planes, often appearing as a doublet or as a tetrad with adjacent sides flattened. It grew well, although slowly, on rich solid medium (LB agar) and in liquid brain-heart infusion at room temperature (ca. 22°C); growth was slower and less extensive at 30°C or 37°C. No growth was seen at 4–5°C or at 42°C. It withstands brief exposure to ultraviolet radiation. Its growth was inhibited by low levels (0.1 unit/ml) of penicillin but was unaffected by levels of acetazolamide in excess of 1 mg/ml, indicating that it lacks carbonic anhydrase. Acid was not produced from glucose, maltose, mannose, lactose, or sucrose and only weakly, if at all, from fructose. Its DNA has a G+C mol percent of 59 measured chromatographically and neither the DNA nor rRNA from the organism hybridized with DNA from any organism that seemed related on morphological or other bases. Thin-layer chromatography of chloroform: methanol extracts of the organism show that it contains phosphatidyl choline, phosphatidyl ethanolamine, and phosphatidyl glycerol. Cell-wall preparations contain glutamic acid, serine, histidine, lysine, and alanine in the ratio of 1:1:1:1:8. Colonies were red-orange in color due, in larger measure, to a carotenoid tentatively identified as rhodopin. The organism was named Pelczaria aurantia.
