Abstract:
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-37^T as the type strain (= CCM 9260^T = LMG 32728^T); Flavobacterium plantiphilum sp. nov., with the strain ST-87^T as the type strain CIP 112180^T = DSM 114790^T = LMG 32757^T); Flavobacterium rhizophilum sp. nov., with the strain ST-75^T as the type strain (= CIP 112185^T = DSM 114831^T = LMG 32758^T); Flavobacterium rhizosphaerae sp. nov., with the strain ST-119^T as the type strain (CIP 112181^T = DSM 114832^T = LMG 32756^T); and Sphingomonas plantiphila sp. nov. with the strain ST-64 ^T as the type strain (= CCM 9261^T = CIP 112178^T = DSM 114515^T = LMG 32729^T).
