'''''Ruminococcus albus'' AD2013'''

''Ruminococcus albus'' AD2013 (DSM 115563) was isolated from the plant-adherent fraction of bovine rumen contents in NZ [1, cow D]. AD2013 has not been phenotypically characterized but its genome encodes a broad range of carbohydrate active enzymes, as well as proteins containing dockerin and carbohydrate-binding domains. AD2013 is predicted to be cellulolytic, and to have similar metabolism to ''Ruminococcus albus'' 7.

The draft genome for AD2013 (4,234,989 bp) was generated through the Hungate1000 project with JGI [2].

NCBI: ''Ruminococcus albus''/''Hominimerdicola alba''

GTDB: ''Hominimerdicola alba_A''. AD2013 belongs to a different species group than the type strain of ''H. alba'' (7, DSM 20455) [3].

Risk group: 1.
