| halomicrobium mukohataei gen. nov., comb. nov., and emended description of halomicrobium mukohataei. | haloarcula mukohataei, previously isolated from soils of salt flats in argentina, was originally placed in the genus haloarcula on the basis of 16s rrna gene sequence comparison. however, its morphology and polar lipid composition differs from that of the other haloarcula species. in addition, its phylogenetic distance from other haloarcula species is rather large, and the 16s rdna sequence does not contain many of the signature bases characteristic of the genus. transfer of the species to a new ... | 2002 | 12361294 |
| phylogenetic relationships within the order halobacteriales inferred from 16s rrna gene sequences. | phylogenetic relationships within the halophilic archaea were inferred from comparisons of the 16s rrna gene sequences from 61 strains, representing 18 genera with validly published names within the order halobacteriales. trees produced using distance-matrix (least-squares and neighbour-joining) methods affirm with strong bootstrap support that the members of the order halobacteriales are a monophyletic group. ten genera were supported as monophyletic groups [haloarcula, halobiforma, halococcus, ... | 2006 | 16738095 |
| 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 |
| intraspecific polymorphism of 16s rrna genes in two halophilic archaeal genera, haloarcula and halomicrobium. | all members of the genera haloarcula and halomicrobium whose names have been validly published were surveyed for 16s rrna gene polymorphism, and the transcription of the genes from two species was investigated during growth at different nacl concentrations. the species of haloarcula and halomicrobium harbour at least two different 16s rrna gene copies, and 18 new sequences of 16s rrna genes were obtained. the type i and type ii 16s rrna genes of haloarcula are divergent at 4.8-5.6% of their nucl ... | 2009 | 18836684 |
| halomicrobium katesii sp. nov., an extremely halophilic archaeon. | two extremely halophilic archaea, strains al-5(t) and k-1, were isolated from lake tebenquiche (atacama saltern, chile) and ezzemoul sabkha (algeria), respectively. cells of the two strains were short-rod-shaped and gram-negative; colonies were orange-pigmented. they grew optimally at 37-40 degrees c and ph 7.0-7.5 in the presence of 25 % (w/v) nacl. magnesium was not required. polar lipid analysis revealed the presence of phosphatidylglycerol and phosphatidylglycerophosphate methyl ester, the a ... | 2008 | 18842855 |
| a unique group of virus-related, genome-integrating elements found solely in the bacterial family thermaceae and the archaeal family halobacteriaceae. | viruses sh1 and p23-77, infecting archaeal haloarcula species and bacterial thermus species, respectively, were recently designated to form a novel viral lineage. in this study, the lineage is expanded to archaeal halomicrobium and bacterial meiothermus species by analysis of five genome-integrated elements that share the core genes with these viruses. | 2010 | 20400546 |
| complete genome sequence of halomicrobium mukohataei type strain (arg-2). | halomicrobium mukohataei (ihara et al. 1997) oren et al. 2002 is the type species of the genus halomicrobium. it is of phylogenetic interest because of its isolated location within the large euryarchaeal family halobacteriaceae. h. mukohataei is an extreme halophile that grows essentially aerobically, but can also grow anaerobically under a change of morphology and with nitrate as electron acceptor. the strain, whose genome is described in this report, is a free-living, motile, gram-negative eur ... | 2009 | 21304667 |
| halomicrobium zhouii sp. nov., a halophilic archaeon from a marine solar saltern. | a halophilic archaeal strain tbn51(t) was isolated from a marine solar saltern in jiangsu, china. the colonies were red-pigmented and the cells were pleomorphic, motile, and stained gram-negative. it was able to grow at 20-55 °c (optimum 42 °c), at 1.4-5.1 m nacl (optimum 2.6 m nacl), at 0-1.0 m mgcl2 (optimum 0.05 m mgcl2) and at ph 5.5-9.5 (optimum ph 7.0). cells lysed in distilled water and the minimal nacl concentration to prevent cell-lysis was 8 % (w/v). the major polar lipids of strain tb ... | 2011 | 21764983 |
