The Clostridia are a class of Firmicutes, including Clostridium and other similar genera. They are distinguished from the Bacilli by lacking aerobic respiration. Studies show they are not a monophyletic group, and their relationships are not entirely certain. Most are currently placed within a single order, called Clostridiales. Some enzymes included are used in bioremediation. Classes Bacilli Clostridia Mollicutes The Firmicutes are a division of bacteria, most of which have Gram-positive stains. ...

Orders Bacillales Lactobacillales The term bacilli (singular bacillus) is used to refer to any rod-shaped bacteria. ... Look up Aerobic in Wiktionary, the free dictionary. ... Families Acidaminococcaceae Clostridiaceae Eubacteriaceae Heliobacteriaceae Lachnospiraceae Peptococcaceae Peptostreptococcaceae Syntrophomonadaceae The Clostridiales are an order of Clostridia bacterium, containing eight families. ... Bioremediation can be defined as any process that uses microorganisms, fungi, green plants or their enzymes to return the environment altered by contaminants to its original condition. ...
Most clostridia will not grow under aerobic conditions and vegetative cells are killed by exposure to O2, but their spores are able to survive long periods of exposure to air.
The clostridia are ancient organisms that live in virtually all of the anaerobic habitats of nature where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals.
Clostridia are able to ferment a wide variety of organic compounds.
