Abstract
Ruminiclostridium sufflavum DSM 19573(T) and Anaerosphaera aminiphila DSM 21120(T) were first isolated from a methanogenic bioreactor treating cattle waste in Hokkaido, Japan. The R. sufflavum draft genome sequence is 4.4 Mb with 3,773 predicted genes, and the A. aminiphila draft genome sequence is 2.0 Mb with 1,962 predicted genes.
