Phyllobacterium phragmitis sp. nov., an endophytic bacterium isolated from Phragmites australis rhizome in Kumtag Desert

A Gram-negative rod, designated strain 1N-3T, was isolated from a rhizome of Phragmites australis grown in Kumtag Desert, China. Phylogenetic analysis showed that the strain is closely related to Phyllobacterium salinisoli LMG 30173T with 99.0% sequence similarity in the 16S rRNA gene and 92.9% in the atpD gene. Growth was observed at salinities of 0–4% (w/v), over a pH range of 5.0–10.0 (optimum 8.0) and at temperatures of 15–40 °C (optimum 30 °C). The predominant cellular fatty acids were identified as summed feature 8 (C18:1ω7c/C18:1ω6c). The G+C content of strain 1N-3T was determined to be 60.1%. Based on phenotypic, chemotaxonomic, phylogenetic properties and genomic comparison, it is concluded that strain 1N-3T represents a novel species of the genus Phyllobacterium, for which the name Phyllobacterium phragmitis sp. nov. is proposed. The type strain is 1N-3T (=KCTC 62183T =ACCC 60071T).
