Terrestrial tardigrade is known to show very strong anti-environmental character at a dehydrated state called “tun” state. It was reported to be alive after exposed to the hydrostatic pressure of 0.6 GPa, which was almost twice higher than the limit for most bacteria and multi-organisms. However, the limit of the hydrostatic pressure above which tardigrades cannot survive is unknown. We performed an experiment to put tardigrades into high hydrostatic pressure of 7.5 GPa, more than 10-times higher than investigated so far, and convinced that they can survive after exposure to 7.5 GPa for up to 12 h.

Abstract
Terrestrial tardigrade is known to show very strong anti-environmental character at a dehydrated state called “tun” state. It was reported to be alive after exposed to the hydrostatic pressure of 0.6 GPa, which was almost twice higher than the limit for most bacteria and multi-organisms. However, the limit of the hydrostatic pressure above which tardigrades cannot survive is unknown. We performed an experiment to put tardigrades into high hydrostatic pressure of 7.5 GPa, more than 10-times higher than investigated so far, and convinced that they can survive after exposure to 7.5 GPa for up to 12 h.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
