| halalkalicoccus tibetensis gen. nov., sp. nov., representing a novel genus of haloalkaliphilic archaea. | a haloalkaliphilic archaeon (strain ds12t) isolated from lake zabuye, the tibetan plateau, china, was characterized to elucidate its taxonomy. the strain was aerobic, chemo-organotrophic, and grew optimally at 40 degrees c, ph 9.5-10.0 and 3.4 m nacl. cells of strain ds12t were non-motile cocci and stained gram-variable. the major polar lipids of strain ds12t were diphytanyl and phytanyl-sesterterpanyl diether derivatives of phosphatidylglycerol and phosphatidylglycerol phosphate methyl ester. n ... | 2005 | 16280517 |
| halalkalicoccus jeotgali sp. nov., a halophilic archaeon from shrimp jeotgal, a traditional korean fermented seafood. | a novel, extremely halophilic archaeon b3(t) was isolated from shrimp-salted seafood. its morphology, physiology, biochemical features and 16s rrna gene sequence were characterized. strain b3(t) is non-motile, gram-variable, requires at least 10 % (w/v) nacl for growth and grows in the ranges of 21-50 degrees c and ph 6.5-9.0. the dna g+c content of strain b3(t) was 63.2 mol%. phylogenetic analysis based on the 16s rrna gene sequences indicated that strain b3(t) belonged to the genus halalkalico ... | 2007 | 17911300 |
| diversity of halophilic archaea from six hypersaline environments in turkey. | the diversity of archaeal strains from six hypersaline environments in turkey was analyzed by comparing their phenotypic characteristics and 16s rdna sequences. thirty-three isolates were characterized in terms of their phenotypic properties including morphological and biochemical characteristics, susceptibility to different antibiotics, and total lipid and plasmid contents, and finally compared by 16s rdna gene sequences. the results showed that all isolates belong to the family halobacteriacea ... | 2007 | 18050917 |
| phylogenetic analysis of the archaeal community in an alkaline-saline soil of the former lake texcoco (mexico). | the soil of the former lake texcoco is an extreme environment localized in the valley of mexico city, mexico. it is highly saline and alkaline, where na+, cl(-), hco3(-) and co3(2-) are the predominant ions, with a ph ranging from 9.8 to 11.7 and electrolytic conductivities in saturation extracts from 22 to 150 ds m(-1). metagenomic dna from the archaeal community was extracted directly from soil and used as template to amplify 16s ribosomal gene by pcr. pcr products were used to construct gene ... | 2008 | 18097633 |
| archaeal diversity in the haloalkaline lake elmenteita in kenya. | a non-culture approach was used to study the archaeal diversity in lake elmenteita, kenya. five different sampling points were selected randomly within the lake. wet sediments and water samples were collected from each sampling point. in addition, dry mud cake was collected from three points where the lake had dried. dna was extracted from these samples and the 16s rrna genes were amplified using primers described to be domain-specific for archaea. eleven clone libraries were constructed using p ... | 2010 | 19806396 |
| complete genome sequence of halalkalicoccus jeotgali b3(t), an extremely halophilic archaeon. | halalkalicoccus jeotgali b3(t), isolated from salt-fermented seafood from south korea, is an extremely halophilic archaeon belonging to the family halobacteriaceae. here, we present the complete genome sequence of the type strain h. jeotgali b3(t) (3,698,650 bp, with a g+c content of 62.5%), which consists of one chromosome and six plasmids. this is the first complete genome sequence of the halalkalicoccus species. | 2010 | 20601480 |
| haloarchaeobius iranensis gen. nov., sp. nov., an extremely halophilic archaeon isolated from the saline lake aran-bidgol, iran. | strain eb21t was isolated from a brine sample of aran-bidgol salt lake, a saline playa in iran. strain eb21t was orange-red pigmented, motile rod and required at least 2 m nacl but not mgcl(2) for growth. optimal growth was achieved at 3.5 m nacl and 0.2 m mgcl(2). the optimum ph and temperature for growth were ph 7.5 and 40 -¦c, respectively, while it was able to grow over a ph range and a temperature range of 6.0-8.0 and 25-55 -¦c, respectively. analysis of 16s rrna gene sequence revealed that ... | 2011 | 21685256 |
| halovenus aranensis gen. nov., sp. nov., a novel extremely halophilic archaeon fromaran-bidgol salt lake, iran. | a novel red-pigmented halophilic archaeon, strain eb27t, was isolated from aran-bidgolsalt lake, a hypersaline playa in iran. the cells of strain eb27t were nonmotile and pleomorphic, from rods to triangular or disk shaped. strain eb27t needs at least 2.5 m nacl and 0.1 m mgcl2 for growth. optimal growth was achieved at 4 m nacl and 0.5 m mgcl2. the optimum ph and temperature for growth were ph 7.5 and 40 -¦c, respectively, while it was able to grow over a ph range and a temperature range of 6.0 ... | 2011 | 21828022 |
