Four bacterial strains isolated from peat bog soil or swampy meadow in Baden-Württemberg (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 °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, 323T=CIP 111153T=DSM 100043T) and Rouxiella silvae for the Silva group (type strain, 213T=CIP 111154T=DSM 103735T). The definition of the genus Rouxiellahas also been emended in order to take these two novel species into account.
