| survey of archaeal diversity reveals an abundance of halophilic archaea in a low-salt, sulfide- and sulfur-rich spring. | the archaeal community in a sulfide- and sulfur-rich spring with a stream water salinity of 0.7 to 1.0% in southwestern oklahoma was studied by cloning and sequencing of 16s rrna genes. two clone libraries were constructed from sediments obtained at the hydrocarbon-exposed source of the spring and the microbial mats underlying the water flowing from the spring source. analysis of 113 clones from the source library and 65 clones from the mat library revealed that the majority of clones belonged t ... | 2004 | 15066817 |
| haloferax sulfurifontis sp. nov., a halophilic archaeon isolated from a sulfide- and sulfur-rich spring. | a pleomorphic, extremely halophilic archaeon (strain m6(t)) was isolated from a sulfide- and sulfur-rich spring in south-western oklahoma (usa). it formed small (0.8-1.0 mm), salmon pink, elevated colonies on agar medium. the strain grew in a wide range of nacl concentrations (6 % to saturation) and required at least 1 mm mg(2+) for growth. strain m6(t) was able to reduce sulfur to sulfide anaerobically. 16s rrna gene sequence analysis indicated that strain m6(t) belongs to the family halobacter ... | 2004 | 15545470 |
| archaeal diversity at the great salt plains of oklahoma described by cultivation and molecular analyses. | the great salt plains of oklahoma is a natural inland terrestrial hypersaline environment that forms evaporite crusts of mainly nacl. previous work described the bacterial community through the characterization of 105 isolates from 46 phylotypes. the current report describes the archaeal community through both microbial isolation and culture-independent techniques. nineteen distinct archaea were isolated, and ten were characterized phenetically. included were isolates phylogenetically related to ... | 2009 | 19306116 |
| phylogenetic diversities and community structure of members of the extremely halophilic archaea (order halobacteriales) in multiple saline sediment habitats. | we investigated the phylogenetic diversity and community structure of members of the halophilic archaea (order halobacteriales) 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) using halobacteriales-specific 16s rrna gene pr ... | 2011 | 22179255 |
