Devosia nitraria sp. nov., a novel species isolated from the roots of Nitraria sibirica in China

Abstract

An aerobic, Gram-stain negative, short rod-shaped and motile strain, 36-5-1T, was isolated from the roots of Nitraria sibirica in Zhangye city, Gansu province, north-west of China. Phylogenetic analysis based on the 16S rRNA gene sequence and two housekeeping genes (glnA and atpD) indicated that the strain represents a novel species closely related to the Devosia, Rhizobium and Devosia genera with 98.3, 96.2 and 91.1% similarities, respectively. The strain 36-5-1T contained Q-10 as the predominant ubiquinone and 16:0 (36.8%) as the major fatty acid; a large amount of unidentified glycolipid, diphosphatidylglycerol, phosphatidylglycerol and a small amount of unidentified polar lipids were present as polar lipids. In addition, the G+C content of the genomic DNA was 61.7 mol% and the DNA–DNA hybridization with type strains Devosia geojensis BD-c194T and Devosia pacifica NH131T 44.1 ± 1.1 and 40.2 ± 1.7, respectively. Based on chemotaxonomic data and molecular properties, strain 36-5-1T represents a novel species within the genus Devosia, for which the name Devosia nitraria sp. nov. is proposed. The type strain is 36-5-1T (=CGMCC1.15704T=NBRC112416T).Electronic supplementary materialThe online version of this article (doi:10.1007/s10482-017-0901-z) contains supplementary material, which is available to authorized users.

Devosia salina sp. nov., isolated from South China Sea sediment

“…S5), D. riboflavina (Fig. S3) and Devosia nitraria [5], but slightly different from D. indica (Fig. S4).…”

“…At the time of writing, the genus Devosia comprises 30 species with validly published names (https://lpsn.dsmz.de/genus/devosia). Members of the genus are ubiquitous in diverse ecological niches including nitrifying inoculum [3], root nodules [4], the roots of Nitraria sibirica [5], soils [6][7][8][9][10], hexachlorocyclohexane dump sites [11,12], alpine glacier cryoconite [13], deep-sea sediments [14][15][16], seawater [17,18], beach sediment [19] and subterranean sediment [20]. It has been reported that the genus has some functions of detoxification and degradation of organic pollutants [21,22].…”

Devosia beringensis sp. nov., isolated from surface sediment of the Bering Sea

“…At the time of writing, the genus Devosia contains 27 species with validly published names (www.bacterio.net/devosia.html). Devosia strains have been isolated from various environments including hexachlorocyclohexane dump site [2], roots of Nitraria sibirica [3] and deep-sea sediments [4]. Members of the genus Devosia are described as Gram-stain-negative, rod-shaped, obligately aerobic, oxidase-positive bacteria, with Q-10 or Q-11 as the predominant respiratory quinone.…”

Plant growth‐promoting activity of endophytic bacteria from sweet sorghum (Sorghum bicolor (L.) Moench)

“…Bacteria from the genus Paenibacillus, Bacillus, Staphylococcus, and Microbacterium are endophytes in sweet sorghum plants (Mareque et al 2015; de Fretes et al 2018. Previous studies reported that bacteria from the genus Devosia were endophytes in the roots of Nitraria (Xu et al 2017) and Brachybacterium were endophytes in rubber plants (Hi dayati et al 2014). The ability of endophytic bacteria as plant growthpromoting bacteria can support the growth of sweet sorghum as well as a solution to reduce the use of chemical fertilizers and pesticides.…”
