“…Several recent studies on the composition of soil microbial diversity in saline soils revealed that soil salinization had negative effects not merely on soil biochemical properties, but also on the structure of microbial communities (Foti et al, 2007;Yuan et al, 2007;Hidri et al, 2013;Wang et al, 2014;Zhang et al, 2015). Regarding the soil microbial community in saline soils of Songnen Plain, only some representative new species of halophilic and halotolerant bacteria and archaea have been reported by pure culture methods (Wu et al, 2008;Wang et al, 2010;Liu et al, 2011b;He et al, 2014;Pan et al, 2016). These microorganisms have gradually formed adaptations, including unique structures and physiological functions, such as the accumulation of osmotic adjustment-related substances (Yan and Marschner, 2012).…”

Songnen Plain is originally one of the three major glasslands in China and has now become one of the three most concentrated distribution areas of sodic-saline soil worldwide. The soil is continuously degraded by natural and anthropogenic processes, which has a negative impact on agricultural production. The investigation of microbial diversity in this degraded ecosystem is fundamental for comprehending biological and ecological processes and harnessing the potential of microbial resources. The Illumina MiSeq sequencing method was practiced to investigate the bacterial diversity and composition in saline-alkali soil. The results from this study show that the change in pH under alkaline conditions was not the major contributor in shaping bacterial community in Songnen Plain. The electrical conductivity (EC) content of soil was the most important driving force for bacterial composition (20.83%), and the second most influencing factor was Na + content (14.17%). Bacterial communities were clearly separated in accordance with the EC. The dominant bacterial groups were Planctomycetes, Proteobacteria, and Bacteroidetes among the different salinity soil. As the salt concentration increased, the indicators changed from Planctomycetes and Bacteroidetes to Proteobacteria and Firmicutes. Our results suggest that Proteobacteria and Firmicutes were the main indicator species reflecting changes of the main microbial groups and the EC as a key factor drives the composition of the bacterial community under alkaline conditions in saline-alkali soil of Songnen Plain.

Likewise, Halostagnicola larsenii, Halostagnicola kamekurae, and Halostagnicola sp. A56 were co-located on a separate branch in the phylogenetic tree (Fig. 1). The ANI/AAI values between Hs. larsenii, the type species of the genus, and Hs. kamekurae and Halostagnicola sp. A56 were 87.16%/86.61% and 86.88%/86.84%, respectively. Therefore, the proposals that Halostagnicola is a novel genus (Castillo et al., 2006b), and that Hs. kamekurae is a novel species of this genus (Nagaoka et al., 2010), are valid. It is also likely that Halostagnicola sp. A56, whose ANI/AAI value with Hs. kamekurae was 92.10%/91.64%, represents a novel species that is yet to be characterized and named. Furthermore, Natronococcus occultus, Natronococcus amylolyticus, and Natronococcus jeotgali were co-located on a separate branch in the phylogenetic tree (Fig. 1). The ANI/AAI values between Nc. occultus, the type species of the genus, and Nc. amylolyticus and Nc. jeotgali were 85.82%/84.69% and 87.01%/84.22%, respectively. Hence, the proposals that Natronococcus is a novel genus (Tindall et al., 1984), and that Nc. amylolyticus and Nc. jeotgali are novel species of this genus (Kanal et al., 1995;Roh et al., 2007), are valid. The genus Natrialba and a potentially novel genus within subclade 5AThe novel genus Natrialba containing a single species was proposed by Kamekura and Dyall-Smith (1995). Since then, the names of five species of Natrialba have been validly published. As of July 2019, the genome sequences of all six species of Natrialba have been sequenced, with Natrialba magadii ATCC 43099 T being sequenced twice (Table 1). Subclade 5A in the phylogenetic tree ( Fig. 1) contained two distinct branches, each having three species of Natrialba. The ANI/AAI value between Natrialba taiwanensis and Natrialba aegyptia was 94.83%/95.00%. Since the DNA-DNA hybridization level between Na. taiwanensis and Na.aegyptia was reported to be 66% (Hezayen et al., 2001), it is likely that these two species are very closely related. The DNA-DNA hybridization level between Natrialba asiatica, the type species of the genus, and Na. taiwanensis was reported to be 55.8% (Hezayen et al., 2001), indicating that they are two different species. This is supported by the fact that the ANI/AAI value between these archaea was 93.12%/92.95%. Furthermore, the ANI/AAI value between Natrialba chahannaoensis and Na. magadii was 88.84%/88.17%, the ANI/AAI value between Na. magadii and Natrialba hulunbeirensis was 89.40%/89.61%, and the ANI/AAI value between Na. chahannaoensis and Na. hulunbeirensis was 88.78%/89.90%. This result confirms the proposal by Xu et al. (2001) that Na. chahannaoensis and Na. hulunbeirensis are distinct from each other, and from Na. magadii.However, the ANI/AAI values between Na. asiatica and Na. chahannaoensis, Na. magadii, Na. hulunbeirensis, and Natrialba sp. SSL1 were 82.17%/76.00%, 82.58%/76.21%, 82.55%/76.30%, and 82.75%/75.75%. Interestingly, Hezayen et al. (2001) had reported that the 16S rDNA sequence similarity between Na. asiatica and N...

“…Since halophilic enzymes from the haloarchaea are generally considered to be active and stable at high salt concentrations, they have potential for biotechnological applications such as engineering for salt-resistant plants in agriculture, environmental bioremediation of organic pollutants and production of fermented foods. The genus Haloterrigena was first proposed by Ventosa et al [ 4 ] with the reclassification of Halococcus turkmenicus as Haloterrigena turkmenica [ 4 ], and presently includes nine species: H. turkmenica [ 4 ], H. thermotolerans [ 5 ], H. longa , H. limicola [ 6 ], H. saccharevitans [ 7 ], H. hispanica [ 8 ], H. jeotgali [ 9 ], H. salina [ 10 ], and H. daqingensis [ 11 ], all of which are pleomorphic, Gram-negative staining, and red- or light pink-pigmented. However, the genus Haloterrigena is poorly characterized at the genome level.…”

Haloterrigena jeotgali is a halophilic archaeon within the family Natrialbaceae that was isolated from shrimp jeotgal, a traditional Korean salt-fermented food. A29T is the type strain of H. jeotgali, and is a Gram-negative staining, non-motile, rod-shaped archaeon that grows in 10 %–30 % (w/v) NaCl. We present the annotated H. jeotgali A29T genome sequence along with a summary of its features. The 4,131,621 bp genome with a GC content of 64.9 % comprises 4,215 protein-coding genes and 127 RNA genes. The sequence can provide useful information on genetic mechanisms that enable haloarchaea to endure a hypersaline environment.
