Altererythrobacter troitsensis sp. nov., isolated from the sea urchin Strongylocentrotus intermedius

Abstract

An aerobic, halotolerant, Gram-negative bacterium was isolated from the sea urchin Strongylocentrotus intermedius and subjected to taxonomic characterization. The strain, designated KMM 6042 T , was rod-shaped, motile and yellow-pigmented. Phylogenetic analysis indicated that the strain was most closely related to the type strain of Altererythrobacter dongtanensis, and the level of 16S rRNA gene sequence similarity between the two was 99.0 %. However, the DNA-DNA relatedness between the two strains was 34.4±7.6 %. Physiological and chemotaxonomic properties clearly distinguished the novel strain from other species of the genus Altererythrobacter. It is thus evident from the phylogenetic and phenotypic analyses that strain KMM 6042T merits recognition as a novel species of the genus Altererythrobacter, for which the name Altererythrobacter troitsensis sp. nov. (type strain, KMM 6042 T 5KCTC 12303T 5JCM 17037 T ) is proposed.

Genomic-based taxonomic classification of the family Erythrobacteraceae

“…The family Erythrobacteraceae , belonging to the order Sphingomonadales , class Alphaproteobacteria [1], is distributed globally, inhabiting various environments including subterrestrial, lake, intertidal areas, mangrove, coastal and deep-sea sediments [2–10], soil [11–13], desert sands [14, 15], a stadium seat [16], seawater [17–19], estuary water [20–22], fresh water [23, 24], hot springs [25–27], air [28] as well as plants and animals [29–36] (Table S1, available in the online version of this article). The members of the family Erythrobacteraceae are Gram-stain-negative, rod or pleomorphic coccoid-shaped, pink-, red-, orange- or yellow-pigmented, and aerobic chemoorganotrophs [1].…”

Draft Genome Sequence of Altererythrobacter troitsensis JCM 17037, Isolated from the Sea Urchin Strongylocentrotus intermedius

“…It accommodates bacteria inhabiting various habitats, such as marine sediment ( 1 , 2 ), seawater ( 3 – 5 ), tidal flats ( 6 ), the rhizosphere of wild rice ( 7 ), desert sand ( 8 ), etc. Interestingly, Altererythrobacter troitsensis JCM 17037 was isolated from the sea urchin Strongylocentrotus intermedius ( 9 ). Here, we present the draft genome of A. troitsensis JCM 17037 to facilitate the study of its physiology, adaptation, and evolution.…”

Altererythrobacter atlanticus sp. nov., isolated from deep-sea sediment

“…At the time of writing, the genus Altererythrobacter comprises 12 species with validly published names. Members of the genus Altererythrobacter have been isolated from seawater (Seo & Lee, 2010; Park et al , 2011), marine sediment (Kwon et al , 2007; Matsumoto et al , 2011), the rhizosphere of wild rice associated with mangrove (Kumar et al , 2008), tidal flats (Yoon et al , 2005; Fan et al , 2011; Jeong et al , 2013), desert sand (Xue et al , 2012) and a sea urchin (Nedashkovskaya et al , 2013). The members of the genus Altererythrobacter are characterized by the yellow to orange–red colony colour on plates, lack of bacteriochlorophyll, C 18 : 1 ω7 c as major fatty acid, and Q-10 as predominant respiratory quinone.…”
