Tumebacillus Algifaecis
''Tumebacillus'' is a genus of Gram-positive, rod-shaped, spore-forming bacteria. Members of the genus can be motile or non-motile, and form white or yellow colonies on R2A agar. The genus was first proposed in 2008 from the discovery of a potentially 5000-7000 year-old bacterium from Canadian high arctic permafrost, which would become the type strain of the genus ''Tumebacillus permanentifrigoris, T. permanentifrigoris''. The genus name was derived from Latin ''tume'' (from ''tumefacere'', to make swollen) and ''bacillus'' (small rod), referring to the swollen sporangia produced by ''T. permanentifrigoris'' and the shape of the cells. Members of this genus have been isolated from arctic permafrost, soil samples, cassava wastewater, decomposing algal scum, river water, and the gut of a vulture. ''Tumebacillus'' was found during surveys of nasal airways of infants, an underground subway in Norway, and a mountain observatory in Austria. Phylogeny The currently accepted taxonomy is ...

Tumebacillus Permanentifrigoris
''Tumebacillus permanentifrigorisis'' is a species of Gram positive, strictly aerobic, bacterium. The cells are rod-shaped and form spores. It was first isolated from a 9-meter-deep permafrost Permafrost () is soil or underwater sediment which continuously remains below for two years or more; the oldest permafrost has been continuously frozen for around 700,000 years. Whilst the shallowest permafrost has a vertical extent of below ... sample from the Canadian high Arctic. The species was first described in 2008, and the name refers to its original isolation from permafrost. ''T. permanentifrigoris'' was the first species in the new genus, ''Tumebacillus'', and is the type species for the genus. The isolate may have survived 5000–7000 years in ice before being discovered. The optimum growth temperature for ''T. permanentifrigoris'' is 25-30 °C, and can grow in the 5-37 °C range and in pH 5.5-8.9. The bacterium would not grow in liquid broth media, but formed y ...
