Picrophilaceae Explained

Picrophilaceae is a family of microbes within the order Thermoplasmatales.

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.^[1]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)^[2] and National Center for Biotechnology Information (NCBI).^[3]
