Original-"Halobacteriaceae"[edit]

In taxonomy, the Halobacteriaceae are a family of the Halobacteriales in the domain Archaea.[4] Halophilic Archaea are represented primarily by members of the family Halobacteriaceae, but also include methanogens from the genera Methanohalophilus and Methanohalobium that occur in the sediments of hypersaline lakes. The members of family Halobacteriaceae solubilized phosphorus under the hypersaline regions. All phosphate solubilizing archaeal sequences obtained in our study by 16S rDNA amplification from the environment grouped within the Halobacteriaceae. P solubilizing capability of haloarchaea indicates that many more cultivable economically important archaeal stains await discovery and utilization in agriculture and allied sectors[5]

In taxonomy, the Halobacteriaceae are a family of the Halobacteriales in the domain Archaea.[4] Data extracted from the "NCBI taxonomy resources". National Center for Biotechnology Information. Retrieved 2007-03-19.</ref> Halobacteriaceae represent a large part of halophilic Archaea, along with members in two other methanogenic families, Methanosarcinaceae and Methanocalculaceae.[6] The family consists of many diverse genera that fill extreme environmental niches. They include neutrophiles, acidophiles (ex. Halarchaeum acidiphilum), alkaliphiles (ex. Natronobacterium), and there have even been psychrotolerant species discovered (ex. Hrr. lacusprofundi).[7] Some members have been known to live aerobically, as well as anaerobically, and they come in many different morphologies.[7] Most species of Halobacteriaceae are best known for their high salt tolerance and red-pink pigmented members, but there are also non-pigmented species and those that require moderate salt conditions.[7][8] Some species of Halobacteriaceae have been shown to exhibit phosphorus solubilizing activities that contribute to phosphorus cycling in hypersaline environments.[9] Techniques such as 16S rRNA analysis and DNA-DNA hybridization have been major contributors to taxonomic classification in Halobacteriaceae, partly due to the difficulty in culturing halophilic Archaea.[8][7][6]

Edit 2-"Halobacteriaceae"[edit]

In taxonomy, the Halobacteriaceae are a family of the Halobacteriales in the domain Archaea.[4] Halobacteriaceae represent a large part of halophilic Archaea, along with members in two other methanogenic families, Methanosarcinaceae and Methanocalculaceae.[6] The family consists of many diverse genera that can survive extreme environmental niches.[7] Most commonly, Halobacteriaceae are found in hypersaline lakes and can even tolerate sites polluted by heavy metals.[10] They include neutrophiles, acidophiles (ex. Halarchaeum acidiphilum), alkaliphiles (ex. Natronobacterium), and there have even been psychrotolerant species discovered (ex. Hrr. lacusprofundi).[7] Some members have been known to live aerobically, as well as anaerobically, and they come in many different morphologies.[7] These diverse morphologies include rods in genus Halobacterium, cocci in Halococcus, flattened discs or cups in Haloferax, and other shapes ranging from flattened triangles in Haloarcula to squares in Haloquadratum, and Natronorubrum.[11][12] Most species of Halobacteriaceae are best known for their high salt tolerance and red-pink pigmented members (due to bacterioruberin carotenoids[11]), but there are also non-pigmented species and those that require moderate salt conditions.[7][8] Some species of Halobacteriaceae have been shown to exhibit phosphorus solubilizing activities that contribute to phosphorus cycling in hypersaline environments.[9] Techniques such as 16S rRNA analysis and DNA-DNA hybridization have been major contributors to taxonomic classification in Halobacteriaceae, partly due to the difficulty in culturing halophilic Archaea.[8][7][6]
