intrasporangiaceae intrasporangiaceae intrasporangiaceae is an actinomycete family. the family is named after the type genus intrasporangium. the type species of intrasporangium (i. calvum) 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. intrasporangiaceae scientific classification domain: bacteria phylum: actinomycetota class: actinomycetia order: micrococcales family: intrasporangiaceaerainey et al. 1997 type genus intrasporangiumkalakoutskii et al. 1967 (approved lists 1980) genera aquipuribacter tóth et al. 2012 fodinibacter wang et al. 2009 humibacillus kageyama et al. 2008 intrasporangium kalakoutskii et al. 1967 (approved lists 1980) janibacter martin et al. 1997 knoellia groth et al. 2002 kribbia jung et al. 2006 lapillicoccus lee and lee 2007 marihabitans kageyama et al. 2008 ornithinibacter xiao et al. 2011 ornithinicoccus groth et al. 1999 oryzihumus kageyama et al. 2005 oryzobacter kim et al. 2015 pedococcus nouioui et al. 2018 phycicoccus lee 2006 segeticoccus lee and whang 2020 terrabacter collins et al. 1989 terracoccus prauser et al. 1997 tetrasphaera maszenan et al. 2000 synonyms aquipuribacteraceae salam et al. 2020 phylogeny the currently accepted taxonomy is based on the list of prokaryotic names with standing in nomenclature and the phylogeny is based on whole-genome sequences. intrasporangiaceae intrasporangium janibacter tetrasphaera pedococcus phycicoccus knoellia outgroups dermacoccaceae notes aquipuribacter, fodinibacter, humibacillus, kribbia, ornithinibacter, ornithinicoccus, oryzihumus, oryzobacter, segeticoccus, terrabacter, and terracoccus are not included in this phylogenetic tree.
