The isolation of living microorganisms from primary 250-million-year-old (MYA) salt crystals has been questioned by several researchers. The most intense discussion has arisen from questions about the texture and age of the crystals used, the ability of organisms to survive 250 million years when exposed to environmental factors such as radiation and the close similarity between 16S rRNA sequences in the Permian and modern microbes. The data in this manuscript are not meant to provide support… 

Ribosomal RNA gene fragments from fossilized cyanobacteria identified in primary gypsum from the late Miocene, Italy

This investigation investigates morphologically, biochemically and genetically primary evaporites deposited in situ during the late Miocene (Messinian) Salinity Crisis from the north-eastern Apennines of Italy and successfully extracts and amplified genetic material belonging to ancient cyanobacteria from gypsum crystals dating back to 5.910-5.816 Ma, which represents the oldest cyanobacterial DNA to date.

Phenotypic Characterization of Halophilic Bacteria Isolated From Çamalti Saltern in Turkey

P phenotypic properties and enzymatic properties of prokaryotic populations of water samples obtained from pools of Camalti saltern showed that these bacteria represents probably different genus and species of either Archaeal or Bacterial domains.

Ancient mitogenomics.

Intact DNA in ancient permafrost.

Virgibacillus salarius sp. nov., a halophilic bacterium isolated from a Saharan salt lake.

The distinct characteristics demonstrated by strain SA-Vb1(T) represent properties of a novel species of the genus Virgibacillus, for which the name VirgIBacillus salarius sp.

Revisiting Jurassic Park: The Isolation of Proteins from Amber Encapsulated Organisms Millions of Years Old

Dominican Republic amber from the Oligo-Miocene epoch, 20–40 million years ago, was interrogated for residual protein, leading to the identification of 84 peptides from 19 Saccharomyces proteins.

Continental evaporites and the search for evidence of life on Mars

Continental evaporites are deposits that originate from the evaporation of saline waters in the low areas of saline lakes from all continents, except Europe, and mainly consist of chloride, sulphate

4.2: Classifying Prokaryotes and Examples

  • Biology
Prokaryotes do not reproduce sexually, so it is not possible to classify them according to the presence or absence of interbreeding, and the nucleotide sequences in genes (particularly rRNA) have become an important criterion of microbial classification.

4.6 Archaea

The genomes of Archaea are larger and more complex than those of bacteria, and some contain a structurally similar substance called pseudopeptidoglycan or pseudomurein.

In vivo multi-dimensional information-keeping in Halobacterium salinarum

It is proposed that digital information archives composed in 3 or more dimensions may be inserted into halophilic organisms and preserved intact for indefinite periods of time.



Isolation of a 250 million-year-old halotolerant bacterium from a primary salt crystal

The isolation and growth of a previously unrecognized spore-forming bacterium (Bacillus species, designated 2-9-3) from a brine inclusion within a 250 million-year-old salt crystal from the Permian Salado Formation is reported.

The question of uniqueness of ancient bacteria

A discussion on the reasons for the homogeneity of ancient and modern microbes is presented and it is probably unreasonable to expect these organisms to be vastly different from modern isolates.

The Permian bacterium that isn't.

The proof-of- the-pudding-is-in-the-eating principle is applied to test whether the newly reported B. permians 16S ribosomal RNA gene sequence is ancient or not.

New evidence for 250 Ma age of halotolerant bacterium from a Permian salt crystal

The purported oldest living organism, the spore-forming bacterium Virgibacillus sp. Perm- ian strain 2-9-3, was recently cultured from a brine inclusion in halite of the 250 Ma Permian Salado

Similarity Analysis of DNAs

All of the procedures discussed in the chapter have been used extensively by bacteriologists and use thermal denaturation, high-performance liquid chromatography (HPLC), or dye-binding fluorimetry.

The paradox of the "ancient" bacterium which contains "modern" protein-coding genes.

Using the most scrupulous and well-documented sampling procedures and contamination-protection techniques reported to date, Vreeland, Rosenzweig, and Powers reported the isolation of a sporeforming bacterium, Bacillus strain 2-9-3, from a brine inclusion within a halite crystal recovered from the 250-Myr-old Permian Salado Formation in Carlsbad, NM.

Bacillus marismortui sp. nov., a new moderately halophilic species from the Dead Sea.

The isolates isolated from enrichments prepared from Dead Sea water samples collected 57 years ago should be regarded as members of a new species of the genus Bacillus, for which the name Bacillus marismortui sp.

Biogeology: How old are bacteria from the Permian age?

It is argued that, although the Permian age of these well-documented deposits is not in question, the fluid inclusions and the viable bacterial spores contained in them may represent much more recent features and the age ofThese microbes must therefore remain uncertain.

Bacillus salexigens sp. nov., a new moderately halophilic Bacillus species.

Six moderately halophilic, grampositive, rod-shaped strains isolated from salterns and hypersaline soils located in different geographical areas of Spain constitute a homology group with levels of DNA-DNA homology ranging from 73 to 100%.

Modern Bacterial Taxonomy

This chapter discusses the choice between phenetic and phylogenetic classifications, interactions between taxonomy and allied disciplines, and general considerations of data for phylogeny.
