Rouxiella badensis sp nov and Rouxiella silvae sp nov isolated from peat bog soil and emendation description of the genus Rouxiella

Four bacterial strains isolated from peat bog soil or swampy meadow in Baden-Wurttemberg (Germany) and found to have rrs sequences close to that of Rouxiella chamberiensis were compared to this species by using multi-locus sequence analysis and phenotypic tests. The four strains constituted two discrete groups (referred to as the Baden and the Silva groups) belonging to the genus Rouxiella. These groups differed in their ability to grow at 37 degrees C, reduce nitrate into nitrite, and to produce acid from several carbohydrates. Two novel species are, therefore, proposed: Rouxiella badensis sp. nov. for the Baden group (type strain, 323(T) = CIP 111153(T) = DSM 100043(T))and Rouxiella silvae for the Silva group (type strain, 213(T) = CIP 111154(T) = DSM 103735(T)). The definition of the genus Rouxiella has also been emended in order to take these two novel species into account.
