Examples
Examples of obligately anaerobic bacterial genera include Actinomyces, Bacteroides,  Clostridium, Fusobacterium, Peptostreptococcus, Porphyromonas, Prevotella, Propionibacterium, and Veillonella. Clostridiumspecies are endospore-forming bacteria, and can survive in atmospheric concentrations of oxygen in this dormant form. The remaining bacteria listed do not form endospores.

Several species of the Mycobacterium, Streptomyces, and Rhodococcus generas are examples of obligate anaerobe found in soil.

Examples of obligately anaerobic fungal genera include the rumen fungi Neocallimastix, Piromonas, and Sphaeromonas.

In July 2019, a scientific study of Kidd Mine in Canada discovered sulfur-breathing organisms which live 7900 feet below the surface. These organisms are also remarkable for eating rocks such as pyrite as their regular food source.
