Names Intrasporangium calvum DSM 43043
Accession numbers NC_014830
Background Intrasporangium calvum (strain ATCC 23552 / DSM 43043 / JCM 3097 / NBRC 12989 / 7 KIP) is an airborne Gram-negative bacterium isolated from under nonselective conditions on plates of meat-peptone agar exposed to the atmosphere of a school dining room (1967). The name Intrasporangium, was selected to emphasize the possibility of intercalary formation of sporangia in mycelial filaments. I. calvum forms a branching mycelium, which tends to break into irregular fragments. The mycelium may bear intercalary vesicles but does not contain spores. The vesicles are ovoid and lemon-shaped. The mycelial filaments penetrate the agar and form compact, small colonies. I. calvum is able to grow between 28 and 37 degrees Celsius, however, the cells grow faster at 37 degrees Celsius than 28 degrees Celsius, but it does not at 45 degrees Celsius. It is able to reduce nitrate to nitrite when KNO3 is added to the growth medium. One particularly interesting feature of I. calvum is that the type of its menaquinone is different from all other representatives of the family Intrasporangiaceae. (Adapted from PMID: 21304734).
