Aliidiomarina iranensis sp. nov., a haloalkaliphilic bacterium from a coastal-marine wetland

Abstract

Aliidiomarina iranensis sp. nov., a haloalkaliphilic bacterium from a coastal-marine wetland A novel Gram-stain-negative, straight rod-shaped, non-pigmented, slightly halophilic and alkaliphilic bacterium, designated strain GBPy7 T , was isolated from a sample of the coastalmarine wetland Gomishan in Iran. Cells of strain GBPy7 T were motile. Growth occurred on media with 1-15 % (w/v) NaCl (optimum 3 %), at pH 7-10 (optimum pH 8.5) and at 4-45 8C (optimum 37 8C). Phylogenetic analysis based on 16S rRNA gene sequence comparison indicated that strain GBPy7 T belonged to the family Idiomarinaceae. Its closest relatives were Aliidiomarina shirensis AIS T (98.1 % 16S rRNA gene sequence similarity) and other Aliidiomarina species (95.9-94.2 %), together with Idiomarina seosinensis CL-SP19 T (94.3 %) and Idiomarina fontislapidosi F23 T (94.3 %). The major cellular fatty acids of the isolate were iso-C 15 : 0 , iso-C 17 : 0 , iso-C 17 : 1 v9c and C 18 : 1 v7c and its polar lipid profile comprised phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, one unknown phospholipid and one unknown aminophospholipid. Cells of strain GBPy7 T contained ubiquinone Q-8. The G+C content of the genomic DNA of this strain was 51.6 mol%. The level of DNA-DNA relatedness between strain GBPy7 T and A. shirensis IBRC-M 10414 T was 21 %. The physiological, biochemical, genotypic and phylogenetic differences between strain GBPy7 T and other previously described taxa indicate that the strain represents a novel species of the genus Aliidiomarina within the family Idiomarinaceae, for which the name Aliidiomarina iranensis sp. nov. is proposed. The type strain is GBPy7 T (5IBRC-M 10763 T 5CECT 8339 T ).

Aliidiomarina quisquiliarum sp. nov., isolated from landfill leachate

“…Strain Y-6 T and A. taiwanensis MCCC 1A06493 T only differed in their contents of GL and L. The predominant respiratory quinone in strain Y-6 T was ubiquinone 8 (Q-8) which was in agreement with all members of the genus Aliidiomarina [1–11]. Compared with A.…”

“…At the time of writing, the genus comprised twelve recognized species (https://lpsn.dsmz.de/). These species were isolated from various habitats such as seawater, saline lake, saline-alkaline soil, sediment and wetland [1][2][3][4][5][6][7][8][9][10][11]. The members of this family are Gram-stain-negative, mesophilic, aerobic or facultatively anaerobic rods, require sodium ions for growth and show a poor ability to use carbohydrates as sole carbon and energy sources [12].…”

“…The major isoprenoid quinone is ubiquinone 8 (Q-8). The DNA G+C content ranges from 45 to 55 mol% [1][2][3][4][5][6][7][8][9][10][11]. This article describes a strain isolated from a landfill site and which is considered to represent a novel species of the genus Aliidiomarina.…”

Aliidiomarina halalkaliphila sp. nov., a haloalkaliphilic bacterium isolated from a soda lake in Inner Mongolia Autonomous Region, China

“…However, it is distant from both sister genera in the phylogenomic tree based on the 78 core genes [3]. At the time of writing, a total of ten species of this genus were validly published, including Aliidiomarina taiwanensis [1], Aliidiomarina haloalkalitolerans [4], Aliidiomarina shirensis [5], Aliidiomarina minuta [6], Aliidiomarina iranensis [7], Aliidiomarina sanyensis [8], Aliidiomarina soli [9], Aliidiomarina maris [10], Aliidiomarina celeris [11] and Aliidiomarina sedimenti [12]. These species were isolated from a wide variety of habitats, including seawater [1, 4], saline lakes [5, 6], coastal-marine wetland [7], Spirulina platensis cultivation pool [8], soil [9] and sediments [10–12].…”

Aliidiomarina indica sp. nov., isolated from deep seawater

“…At the time of writing, the genus comprised ten recognizedspecies. Members of the genus Aliidiomarina have been isolated from various habitats such as seawater, saline lake, saline-alkaline soil, sediment and wetland [1][2][3][4][5]. In this study, a novel bacterial strain designated as strain SW123 T was investigated in detail using a polyphasic taxonomic approach.…”
