| Sumario: | Members of the genera Flavobacterium, Chryseobacterium and Sphingomonas constitute a group of microorganisms in the rhizosphere associated with plant growth promoting (PGP) features. A polyphasic approach was employed to ascertain the taxonomic status of five selected strains. Overall genome relatedness indices of digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) between the strains and the other members of the genera Flavobacterium, Chryseobacterium and Sphingomonas were found to be below the established thresholds, respectively. Morphological, physiological, and biochemical characteristics of the strains confirmed their status as five novel species. A large variety of genes involved in plant growth promotion and carbohydrate utilization were found in all strains suggesting a contribution of all strains to PGP. Based on the result of the polyphasic characterization, the following names are proposed: Chryseobacterium terrae sp. nov., with the strain ST-37T as the type strain (= CCM 9260T = LMG 32728T); Flavobacterium plantiphilum sp. nov., with the strain ST-87T as the type strain CIP 112180T = DSM 114790T = LMG 32757T); Flavobacterium rhizophilum sp. nov., with the strain ST-75T as the type strain (= CIP 112185T = DSM 114831T = LMG 32758T); Flavobacterium rhizosphaerae sp. nov., with the strain ST-119T as the type strain (CIP 112181T = DSM 114832T = LMG 32756T); and Sphingomonas plantiphila sp. nov. with the strain ST-64 T as the type strain (= CCM 9261T = CIP 112178T = DSM 114515T = LMG 32729T). |
