Intrasporangium is a genus of Gram positive, nonmotile bacteria. The genus name refers to the mycelium of the type strain forming intercalary vesicles that were originally identified as spores. However, no spores have been observed in later studies. [1] The family Intrasporangiaceae is named after the genus, and Intrasporangium is the type genus for the family. [3]
The genus was first proposed in 1967. The type species I. calvum was first isolated from air in a school dining room in the Soviet Union. [1] The genus was monospecific until 2012, when three species were added to the genus. I. chromatireducens and I. mesophilum were proposed as new species, and the monospecific Humihabitans oryzae was reclassified as I. oryzae. [4] [5] The novel genus and species Monashia flava was proposed in 2016, but was later found to be a member of Intrasporagium, most likely a strain of I. oryzae. The genus is currently defunct. [6] [7]
Although the first isolation of Intrasporangium was from an air sample, subsequent isolations have mainly been from various types of soil. The soil sources include a manganese mine, [4] a former coal gasification site, [8] a uranium-contanimated site, [9] and the rhizospheres of a rice paddy and of Jatropha curcas . [5]
Kribbella is a genus of bacteria first discovered in 1999.
Intrasporangiaceae is an actinomycete family. The family is named after the type genus Intrasporangium. The type species of Intrasporangium was originally thought to form endospores; however, the mycelium of this strain may bear intercalary vesicles that were originally identified as spores. No members of Intrasporangiaceae are known to form spores.

Intrasporangium mesophilum is a species of Gram positive, strictly aerobic bacterium. The species was initially isolated from rhizospheric soil of an oilseed plant, Jatropha curcas. The species was first described in 2012, and its name refers to its mesophilic growth conditions.
Phycicoccus is a genus of Gram positive, aerobic, non-endosporeforming bacteria. Species in this genus are mesophilic and have cells that are short rods or coccoid.

The species was first described in 2013, and its name refers to the island from which it was first isolated.
Knoellia is a genus of Gram positive, aerobic, non-endosporeforming bacteria. Species in this genus are mesophilic and have cells that are irregular rods or coccoid.
Knoellia remsis a species of Gram positive, nonmotile, non-sporeforming bacteria. The bacteria are aerobic and mesophilic, and the cells are coccoid that group in pairs, tetrads, or clusters. It was originally isolated from an air sample from the Regenerative Enclosed Life Support Module Simulator, which was a system designed to simulate life aboard the International Space Station. The species is named after REMS, the acronym for the Regenerative Enclosed Life Support Module Simulator. The species was originally classified as Tetrasphaera remsis in 2007, but was reclassified into the genus Knoellia in 2018.
