Popis: A Gram-negative, aerobic, non-spore-forming, rod-shaped, motile bacterium, named strain 59N8T, was isolated from Phragmites communis roots in the Kumtag Desert. Phylogenetic analysis based on the 16S rRNA gene sequence showed that the isolate belongs to the genus Zobellella within the family Aeromonadaceae . The analysis showed that strain 59N8T was most closely related to Zobellella taiwanensis ZT1T. The average nucleotide identity value with Zobellella taiwanensis ZT1T was 88.2 %, and the digital DNA–DNA hybridization value was 29.7±2.4 %, which was calculated using the Genome-to-Genome Distance Calculator. The G+C content of strain 59N8T was 62.8 mol%. Strain 59N8T grew at 0–5 % (w/v) NaCl (optimum, 0–4 %), pH 6.0–9.0 (optimum, 7.0–8.0) and at 10–45 °C. The major cellular fatty acids were summed feature 8 (C18 : 1ω7c/C18 : 1ω6c), summed feature 3 (C16 : 1ω7c/C16 : 1ω6c) and C16 : 0. The major polar lipids in strain 59N8T were phosphatidylethanolamine and phosphatidylglycerol. Based on the chemotaxonomic, phylogenetic and phenotypic data, strain 59N8T represents a novel species in the genus Zobellella , for which the name Zobellella endophytica sp. nov. is proposed. The type strain is 59N8T (=ACCC 60074T=KCTC 62456T).
