Abstract
A Gram-stain-negative, strictly aerobic, slightly halophilic, non-motile and rod-shaped bacterial strain, designated P2E16T, was isolated from mangrove (Avicennia marina) rhizosphere, collected at Devipattinam mangroves, Tamil Nadu, India. Strain P2E16T grew optimally at pH 7.0–8.0, at 25–28 °C and in the presence of 2–3 % (w/v) NaCl. 16S rRNA gene analysis showed that strain P2E16T was phylogenetically closely related to the genus
Zunongwangia
, with
Zunongwangia profunda
SM-A87T as the closest related type strain (98.2 % 16S rRNA gene sequence similarity) and less than 93 % 16S rRNA gene sequence similarity to all other members of the family
Flavobacteriaceae
. Strain P2E16T contained MK-6 as the major respiratory quinone, phosphatidylethanolamine as the predominant polar lipid and iso-C15 : 0 (17.8 %), iso-C17 : 0 3-OH (15.1 %), C15 : 0 (12.8 %), iso-C17 : 1ω9c (9.8 %), iso-C15 : 1 G (9.0 %), and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH; 7.1 %) as the major fatty acids. The DNA G+C content was 34.3 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness and low DNA–DNA relatedness demonstrated that strain P2E16T was distinct from the type strain of
Zunongwangia profunda
. On the basis of these presented data, strain P2E16T is considered to represent a novel species of the genus
Zunongwangia
, for which the name Zunongwangia mangrovi sp. nov. is proposed. The type strain is P2E16T ( = DSM 24499T = LMG 26237T = KCTC 23496T). An emended description of the genus
Zunongwangia
is also provided.
