The bright colors of Grand Prismatic Spring, Yellowstone National Park are produced by thermophilic bacteria. [33] Prokaryotes have diversified greatly throughout their long existence. Their metabolism is far more varied than that of eukaryotes, leading to many highly distinct types. For example, prokaryotes may obtain energy by chemosynthesis ...
This article lists the genera of the bacteria.The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [1] and National Center for Biotechnology Information (NCBI). [2]
Bacteria inhabit soil, water, acidic hot springs, radioactive waste, [61] and the deep portions of Earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals. Once regarded as plants constituting the class Schizomycetes, bacteria are now classified as prokaryotes.
Endospore-forming bacteria can cause disease; for example, anthrax can be contracted by the inhalation of Bacillus anthracis endospores, and contamination of deep puncture wounds with Clostridium tetani endospores causes tetanus, which, like botulism, is caused by a toxin released by the bacteria that grow from the spores.

It consists of all bacteria, which are prokaryotes (lacking nucleus), thus, Domain Bacteria is made up solely of prokaryotic organisms. [62] [63] Some examples are: Cyanobacteria – photosynthesising bacteria related to the plastids of eukaryotes. [64] Spirochaetota – Gram-negative bacteria involved in human diseases like syphilis and lyme ...
Cyanobacteria are globally widespread photosynthetic prokaryotes and are major contributors to global biogeochemical cycles. [28] They are the only oxygenic photosynthetic prokaryotes, and prosper in diverse and extreme habitats. [29] They are among the oldest organisms on Earth with fossil records dating back at least 2.1 billion years. [30]
Vibrio — a genus of comma-shaped bacteria first described in 1854 [11] Bacterium — a genus of rod-shaped bacteria first described in 1828. Haeckel does not explicitly assign this genus to the Monera. Bacillus — a genus of spore-forming rod-shaped bacteria first described in 1835 [12] Haeckel does not explicitly assign this genus to the ...
This article lists the orders of the Bacteria.The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [1] and National Center for Biotechnology Information (NCBI) [2] and the phylogeny is based on 16S rRNA-based LTP release 132 by The All-Species Living Tree Project.
