elusimicrobiota elusimicrobiota the phylum elusimicrobiota, previously known as "termite group 1", has been shown to be widespread in different ecosystems like marine environment, sewage sludge, contaminated sites and soils, and toxic wastes. the high abundance of elusimicrobiota representatives is only seen for the lineage of symbionts found in termites and ants. elusimicrobiota scientific classification domain: bacteria phylum: elusimicrobiotageissinger et al. 2021 classes elusimicrobia endomicrobia synonyms "elusimicrobaeota" oren et al. 2015 "elusimicrobia" geissinger et al. 2009 "elusimicrobiota" whitman et al. 2018 candidate phylum tg1 the first organism to be cultured was elusimicrobium minutum; however, two other species have been partially described and placed in a separate class, known as endomicrobia. phylogeny 16s rrna based ltp_12_2021 gtdb 07-rs207 by genome taxonomy database elusimicrobiales elusimicrobiaceae elusimicrobium minutum endomicrobiales endomicrobiaceae endomicrobium proavitum elusimicrobiales elusimicrobiaceae "ca. avelusimicrobium excrementipullorum" elusimicrobium minutum endomicrobiales endomicrobiaceae endomicrobium e. proavitum "ca. e. trichonymphae" taxonomy the currently accepted taxonomy is based solemnly on the list of prokaryotic names with standing in nomenclature (lpsn) and national center for biotechnology information (ncbi) phylum elusimicrobiota geissinger et al. 2021 class "elusimicrobiia" oren, parte & garrity 2016 ex cavalier-smith 2020 order elusimicrobiales geissinger et al. 2010 family elusimicrobiaceae geissinger et al. 2010 genus "ca. avelusimicrobium" gilroy et al. 2021 species "ca. a. excrementipullorum" gilroy et al. 2021 genus elusimicrobium geissinger et al. 2010 species e. minutum geissinger et al. 2010 class endomicrobia (sic) zheng et al. 2018 order endomicrobiales zheng et al. 2018 family endomicrobiaceae zheng et al. 2018 genus endomicrobium zheng et al. 2018 species e. proavitum zheng et al. 2018 species "ca. e. pyrsonymphae" stingl et al. 2005 species "ca. e. superficiale" izawa et al. 2017 species "ca. e. trichonymphae" stingl et al. 2005
