The persistence of bacterial DNA over geological timespans remains a contentious issue. In direct contrast to in vitro based predictions, bacterial DNA and even culturable cells have been reported from various ancient specimens many million years (Ma) old [1–8]. As both ancient DNA studies and the revival of microorganisms are known to be susceptible to contamination [8–10], it is concerning that these results have not been independently replicated to confirm their authenticity. Furthermore… Expand
Ancient bacteria show evidence of DNA repair
TLDR
The results show evidence of bacterial survival in samples up to half a million years in age, making this the oldest independently authenticated DNA to date obtained from viable cells and find strong evidence that this long-term survival is closely tied to cellular metabolic activity and DNA repair that over time proves to be superior to dormancy as a mechanism in sustaining bacteria viability.

Bacterial natural transformation by highly fragmented and damaged DNA
TLDR
The findings reveal that short and damaged, including truly ancient, DNA molecules, which are present in large quantities in the environment, can be acquired by bacteria through natural transformation, suggesting that natural genetic exchange of DNA from dead and even extinct organisms to contemporary bacteria can take place over hundreds of thousands of years. Expand
Very Old DNA
The DNA molecule degrades over time, just like other cellular components if not repaired. Often the degradation is relatively fast, as fossil remains that are only a few hundred years old containExpand
The study of bacterial DNA in ancient human mummies
TLDR
The analysis of the microbial DNA associated with human remains provides direct evidence of the JASs Invited Reviews. Expand
The past, present and future of ancient bacterial DNA
TLDR
The present avenues of research are summarized and contextualize them in the past of the field whilst also pointing towards questions still to be answered, in this review of bacterial aDNA studies. Expand
Advances in ancient DNA studies
TLDR
A series of large scale studies have begun to reveal the true potential of aDNA to record the methods and processes of evolution, providing a unique way to test models and assumptions commonly used to reconstruct patterns of Evolution, population genetics and palaeoecological change. Expand
Crosslinks Rather Than Strand Breaks Determine Access to Ancient DNA Sequences From Frozen Sediments
TLDR
The results question the reliability of the commonly used models relying on depurination kinetics for predicting the long-term survival of DNA under permafrost conditions and suggest that new strategies for repair of ancient DNA must be considered if the yield of amplifiable DNA from permaf frost sediments is to be significantly increased. Expand
Genetic analyses from ancient DNA.
TLDR
The precautions and criteria necessary to ascertain to the greatest extent possible that results represent authentic ancient DNA sequences are discussed, which highlight some significant results and areas of promising future research. Expand
Review Paper. Ancient DNA
TLDR
Initial results have revealed surprisingly complex population histories, and indicate that modern phylogeographic studies may give misleading impressions about even the recent evolutionary past. Expand
No Ancient DNA Damage in Actinobacteria from the Neanderthal Bone
TLDR
The analyses suggest that the Actinobacteria, and especially members of the Streptomycetales, contribute the majority of sequences in the DNA extracted from the Neanderthal fossil Vi33.16, paving the way for future studies of microbial compositions and patterns of DNA damage in bacteria from archaeological bones.

Characterization of Viable Bacteria from Siberian Permafrost by 16S rDNA Sequencing
TLDR
Viable bacteria were found in permafrost core samples from the Kolyma-Indigirka lowland of northeast Siberia, andPhylogenetic analysis revealed that the isolates fell into four categories: high-GC Gram-positive bacteria, β-proteobacteria, γ- Proteob bacteria, and low- GC Gram- positive bacteria.

Neanderthal DNA: Not just old but old and cold?
TLDR
The thermal history of a range of Holocene and Pleistocene bones whose DNA quality has been tested is calculated and it is found that in only very few sites with Neanderthal remains is the preservation of DNA likely to match the quality of that from the skeleton found at Mezmaiskaya Cave. Expand
Synthesis of Anabiosis Autoinducers by Non-Spore-Forming Bacteria as a Mechanism Regulating Their Activity in Soil and Subsoil Sedimentary Rocks
TLDR
Evidence was obtained indicating that autoregulation of bacterial growth and development is implemented at the level of intercellular interactions in microbial communities, probably a result of special antistress mechanisms responsible for the survival of these bacteria under extreme conditions of natural long-term cooling.
