Clostridium amylolyticum is an anaerobic, endospore-forming bacterium in the family Clostridiaceae notable for its ability to ferment starch (amylon in Greek, giving the species epithet) and other complex carbohydrates to produce organic acids, alcohols, and gases. Like other members of the Clostridium genus, it is a strictly anaerobic rod-shaped bacterium that produces resistant endospores enabling survival in unfavorable environmental conditions, including exposure to heat, desiccation, and oxygen. C. amylolyticum is found in starch-rich anaerobic environments such as soil, sediments, and fermentation systems, where its amylolytic enzymes break down starch polymers into simpler sugars that are then fermented. The genus Clostridium is polyphyletic and has undergone extensive reclassification as molecular phylogenetics revealed it encompasses multiple distinct evolutionary lineages. Amylolytic clostridia have industrial applications in bioprocessing, particularly in biofuel production through simultaneous saccharification and fermentation of starchy biomass feedstocks, and in producing commodity chemicals through anaerobic fermentation.

Clostridium peptidivorans is an anaerobic, endospore-forming bacterium in the family Clostridiaceae specialized in the fermentation of peptides and amino acids, as indicated by the species epithet meaning 'peptide-devouring.' It was isolated from anaerobic environments rich in proteinaceous material, including oil field brine waters and sediments where complex organic nitrogen compounds are abundant. Like all clostridia, it is a strictly anaerobic, Gram-positive, rod-shaped bacterium that forms resistant endospores. C. peptidivorans uses Stickland fermentation reactions — coupled oxidation and reduction of amino acid pairs — to derive energy from peptide and amino acid substrates, producing organic acids, ammonia, and other end products. The ability to metabolize peptides makes it an active participant in the anaerobic degradation of protein-rich organic matter in subsurface environments. Its discovery in oil field environments suggests that peptidivoranous clostridia play roles in the anaerobic cycling of organic nitrogen in deep subsurface biotopes, contributing to biogeochemical processes in petroleum-associated anaerobic microbial communities.
