Sporosarcina pasteurii DSM 33* + 2% urea Isolated from soil M220 + CaCl2 Gram-positive bacilli FA Motile 9.1 ± 0.1

Marine bacteria grew for 3 days on solid media at 25 °C. *Sporosarcina pasteurii DSM 33 was used as a model bacterium for its ability to biomineralize [23]. FA: facultative anaerobe; OA: obligate aerobe.
