Extremely Halophilic Archaea

Two extremely halophilic archaea, strains 9-3T and 31-hongT, were isolated from Aibi salt lake and Aiding salt lake in Xin-Jiang, China. Their morphology, physiology, biochemical features, polar lipid compositions and 16S rRNA gene sequences were characterized in order to elucidate their taxonomic status. The results from this study indicated that strains 9-3T and 31-hongT are members of the genus Halorubrum. Their physiological properties and polar lipid compositions are clearly different from those of the currently described species of Halorubrum. DNA–DNA relatedness values for strain 9-3T with respect to its closely related neighbours Halorubrum saccharovorum JCM 8865T and Halorubrum lacusprofundi JCM 8891T were 51.6 and 25.1 %, respectively, DNA–DNA relatedness values for strain 31-hongT with respect to its closely related neighbours Hrr. saccharovorum JCM 8865T and Hrr. lacusprofundi JCM 8891T were 29.4 and 44.9 %, respectively, and DNA–DNA relatedness between strains 9-3T and 31-hongT was 54 %. Thus, two novel species of the genus Halorubrum are proposed, Halorubrum lipolyticum sp. nov. (type strain 9-3T=CGMCC 1.5332T=JCM 13559T) and Halorubrum aidingense sp. nov. (type strain 31-hongT=CGMCC 1.2670T=JCM 13560T).

Halophilic archaeal strains ABH32T and AX-7T were isolated from Aibi salt lake in Xin-Jiang, China, and were subjected to taxonomic studies. The cells of both strains were rod-shaped, and growth required at least 10 % (w/v) NaCl. The cellular polar lipids were identified as phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and mannose-2,6-disulfate (1→2)-glucose glycerol diether (S2-DGD). The isolates were different in that strain ABH32T did not require magnesium and had strong ability to assimilate sugars for growth, whereas strain AX-7T required magnesium and did not assimilate glucose, sucrose or maltose for growth. Both strain ABH32T and strain AX-7T were most closely related to members of the genera Haloterrigena and Natrinema. On the basis of phenotypic and genotypic characteristics, especially their cellular polar lipids, the two isolates were assigned to the genus Haloterrigena. Moreover, the DNA relatedness values for strains ABH32T and AX-7T with respect to members of the genus Haloterrigena were found to be well below 70 %. Thus, strains ABH32T and AX-7T represent two novel species within the genus Haloterrigena, for which the names Haloterrigena longa sp. nov. (type strain ABH32T=CGMCC 1.5334T=JCM 13562T) and Haloterrigena limicola sp. nov. (type strain AX-7T=CGMCC 1.5333T=JCM 13563T) are proposed.

ABSTRACT The genomes of two extremely halophilic Archaea species, Haloarcula marismortui and Haloferax mediterranei, were sequenced using single-molecule real-time sequencing. The ∼4-Mbp genomes are GC rich with multiple large plasmids and two 4-methyl-cytosine patterns. Methyl transferases were incorporated into the Restriction Enzymes Database (REBASE), and gene annotation was incorporated into the Haloarchaeal Genomes Database (HaloWeb).

Two extremely halophilic archaea, namely, Natrinema versiforme BOL5-4 and Natrinema pallidum BOL6-1, were isolated from a Bolivian salt mine and their genomes sequenced using single-molecule real-time sequencing. The GC-rich genomes of BOL5-4 and BOL6-1 were 4.6 and 3.8 Mbp, respectively, with large chromosomes and multiple megaplasmids. Genome annotation was incorporated into HaloWeb and methylation patterns incorporated into REBASE.

High Durability

In the salt lake areas in China, the ordinary cement concrete can be corroded by the salt in the saline soil seriously, and the application of ordinary portland cement concrete in this area is impeded. Therfore, some new cementitious materials which has high durability should be searched in order to be used in the underground engineering in saline soil areas. In this study, the sulfoaluminate cement is immersed into the salt solution that has high concentration Mg2+, Cl-, SO42-, and the complex solution of them. The corrosion resistance performance of sulfoaluminate cement against high concentration salt solution is tested. The results indicate that Sulfoaluminate cement has perfect durability against sulfate corrosion whose concentration is in the scope of this test. Sulfoaluminate cement can not be corroded by MgCl2 solution when MgCl2 solution concentration is lower than degree 3; but when the concentration of MgCl2 solution reaches degree 4, MgCl2 solution could corrode the sulfoaluminate cement seriously. The corrosion of the specimens immersed in MgCl2 solution whose concentration is degree 4 is caused by the composite action of Mg2+ and Cl-.

ABSTRACTWe investigated the phylogenetic diversity and community structure of members of the halophilicArchaea(orderHalobacteriales) in five distinct sediment habitats that experience various levels of salinity and salinity fluctuations (sediments from Great Salt Plains and Zodletone Spring in Oklahoma, mangrove tree sediments in Puerto Rico, sediment underneath salt heaps in a salt-processing plant, and sediments from the Great Salt Lake northern arm) usingHalobacteriales-specific 16S rRNA gene primers. Extremely diverseHalobacterialescommunities were encountered in all habitats, with 27 (Zodletone) to 37 (mangrove) different genera identified per sample, out of the currently described 38Halobacterialesgenera. With the exception of Zodletone Spring, where the prevalent geochemical conditions are extremely inhospitable toHalobacterialessurvival, habitats with fluctuating salinity levels were more diverse than permanently saline habitats. Sequences affiliated with the recently described generaHalogranum,Halolamina,Haloplanus,Halosarcina, andHalorientalis, in addition to the generaHalorubrum,Haloferax, andHalobacterium, were among the most abundant and ubiquitous genera, suggesting a wide distribution of these poorly studied genera in saline sediments. TheHalobacterialessediment communities analyzed in this study were more diverse than and completely distinct from communities from typical hypersaline water bodies. Finally, sequences unaffiliated with currently described genera represented a small fraction of the totalHalobacterialescommunities, ranging between 2.5% (Zodletone) to 7.0% (mangrove and Great Salt Lake). However, these novel sequences were characterized by remarkably high levels of alpha and beta diversities, suggesting the presence of an enormous, yet-untapped supply of novelHalobacterialesgenera within the rare biosphere of various saline ecosystems.
