caldicellulosiruptor saccharolyticus caldicellulosiruptor saccharolyticus caldicellulosiruptor saccharolyticus is a species of thermophilic, anaerobic cellulolytic bacterium. it was isolated from a piece of wood floating in the flow from a freshwater thermal spring in new zealand in 1987, and tentatively named caldocellum saccharolyticum. in 1994, the isolate was more thoroughly characterized physiologically, and classified to a new genus, caldicellusiruptor, based on 16s rna sequence. it is the type species, and more thoroughly studied member of its genus. caldicellulosiruptor saccharolyticus scientific classification domain: bacteria phylum: bacillota class: clostridia order: thermoanaerobacterales family: thermoanaerobacterales family iii genus: caldicellulosiruptor species: c. saccharolyticus binomial name caldicellulosiruptor saccharolyticusrainey et al., 1995
