Clostridiaceae

The Clostridiaceae are a family of the bacterial class Clostridia, and contain the genus Clostridium.

The family Clostridiaceae (scientific name) defined by the taxonomic outline of '' Bergey's Manual of Systematic Bacteriology contains as its core the genus Clostridium (sensu stricto), as well as Acetivibrio, Acidaminobacter, Alkaliphilus, Anaerobacter, Caloramator, Caloranaerobacter, Coprobacillus, Dorea, Natronincola, Oxobacter, Sarcina, Sporobacter, Thermobrachium, Thermohalobacter, and Tindallia. The previous inclusion of these additional genera (as seen on the right) in a family Clostridiaceae is based for the most part because the type species of these genera are in many cases phylogenetically related to misclassified species of the genus Clostridium. However, with the exception of Anaerobacter, Caloramator, Oxobacter, Sarcina, and Thermobrachium, these genera fall outside the radiation of what can be considered the true family Clostridiaceae and are now regarded as belonging to other families within the low G + C, Gram-positive phylum.
