A Corrigendum on
Living at the Extremes: Extremophiles and the Limits of Life in a Planetary Context
by Merino, N., Aronson, H. S., Bojanova, D. P., Feyhl-Buska, J., Wong, M. L., Zhang, S., et al. (2019) Front. Microbiol. 10:780. doi: 10.3389/fmicb.2019.00780
In the original article, there was a mistake in the legend for Table 4 as published. The legend in Table 4 is missing two parentheses around “Poly.” The correct legend appears below.
“Table 4. Examples of notable (Poly)extremophiles and their physiological requirements.”
Additionally, there was a mistake in Table 3 and Table 5 as published. In Table 3, the lowest temperature listed for Planococcus halocryophilus Or1 is “−18°C.” It should be “−15°C” instead. In addition, the pH range is “nr” but should be “6–11” instead. In the temperature column, 37 is bold type, but this should be regular type.
TABLE 3
Table 3. Limits of life as identified by (poly)extremophilic organisms in pure cultures.
TABLE 5
Table 5. Boundary conditions for different planetary bodies of astrobiological interest (compared to Earth), split into atmosphere, surface, and subsurface layers.
In Table 5, the atmosphere entry for Earth > Atmosphere > Geochemistry is listed as “8.1% N2,” but the actual composition of Earth's atmosphere is “78% N2.”
The corrected Table 3 and Table 5 appear below.
Lastly, there is a grammatical error in the original article.
A correction has therefore been made to the section Can Life Originate, Evolve, or Survive on Other Planetary Bodies?, paragraph five:
“Solar and galactic cosmic rays (high-energy particles with energies from 10 MeV to >10 GeV) present challenges to life on the surface and near-surface of Mars and other planetary bodies. However, any subsurface aquifer deeper than a few meters would be protected from damaging radiation. Dartnell et al. (2007) calculated the galactic cosmic ray dosage rates and the corresponding survival times (which they defined as a million-fold decrease in cell number) of characteristic microbes at different depths in Mars's subsurface. At the surface, E. coli has a survival time of 1,200 years, while at 20-m depth, that survival time jumps to 1.5 × 108 years. Compared to E. coli, D. radiodurans has survival times an order of magnitude longer. These survival times are, in fact, lower limits in light of recent measurements by the Radiation Assessment Detector onboard the Mars Science Laboratory (Hassler et al., 2014), which found that the actual dose rate at Gale Crater (76 mGy year−1) is a factor of 2 lower than that modeled by Dartnell et al. (2007).”
The authors apologize for these errors and state that they do not change the scientific conclusions of the article in any way. The original article has been updated.
