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.

호주 동부와 동남부의 상징적인 유대류로, 체중이 최대 15kg이며 저칼로리인 유칼립투스 잎 식단에서 에너지를 절약하기 위해 하루 최대 22시간을 잠으로 보낸다. 대부분의 다른 포유류를 죽일 수 있는 유독한 유칼립투스 성분을 처리하도록 고도로 특화되어, 해독에 특별히 적응된 장내 미생물총을 지닌다. 2022년 기후 변화, 서식지 개발, 클라미디아 감염으로 인한 개체수 감소로 위기종으로 지정되었다.
