论文摘要：
Abstract 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 (C18:1x7c/
C18:1x6c). The G?C content of strain 1N-3T was
determined to be 60.1%. Based on phenotypic,
chemotaxonomic, phylogenetic properties andgenomic 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).
