'''''Tractidigestivibacter'' sp. KH2P3'''

''Tractidigestivibacter'' sp. KH2P3 was isolated from bovine rumen contents in NZ using KH medium which was supplemented with haemin and vitamin K [1]. KH2P3 is a non-motile, non-spore forming Gram positive, anaerobe which produces D-lactate as the main product from glucose fermentation. KH2P3 is a high G+C lactic acid bacterium and while originally identified as ''Olsenella'' it was subsequently assigned to the genus ''Tractidigestivibacter'' within the family ''Atopobiaceae'' [2].

''Tractidigestivibacter'' species encode glycyl radical enzyme (GRE) superfamily enzymes that catalyse reactions rarely found in other bacteria, such as aromatic amino acid decarboxylases that enable ''T. scatoligenes'' to produce skatole and p-cresol from tryptophan and tyrosine [3]. KH2P3 encodes two arylacetate decarboxylase gene clusters.

The draft genome for KH2P3 (2,421,020 bp) was generated through the Hungate1000 project with JGI [1].
