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

Abstract
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 multi-locus sequence analysis and phenotypic tests. The four strains constituted two discrete groups (referred to as Baden and Silva groups) belonging to the genus Rouxiella. These groups differed in the ability to grow at 37°C, reduce nitrate into nitrite, and produce acid from several carbohydrates. Two new 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 Rouxiella is emended to take the new species into account.
