Picrophilaceae
Scientific classification

Class:	Thermoplasmata
Order:	Thermoplasmatales
Family:	Picrophilaceae Schleper et al., 1996
Genus
Picrophilus

Picrophilaceae is a family of microbes within the order Thermoplasmatales.[1]

Morphology and ecology

The cells are round in shape, thermophilic, heterotrophic, and obligately aerobic. This species is hyperacidophilic, with an optimal pH of 0.7. Its optimal temperature is 60 °C. It has been isolated from fumaroles, acidic sediments, dry solfataric fields, and hot springs in Hokkaidō, Japan.[2]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[3] and National Center for Biotechnology Information (NCBI).[1]
