Don't strain yourself

Bacterias seem harder and harding to kill off.

Strain 121 is a microbe, some sort of bacteria.
This microbe is the only known bacteria (thus far) to survive in an autoclave.
It is the first microbe to be found having survive and reproduce in the temperature used in an autoclave cycle. It subjects the equipment to high pressure steam at 121 °C (250^o F) or more, with a cycle typically running for 15-20 minutes. I don't think Strain 121 broke out in a sweat (lol).

Autoclaves are devices that sterilizes equipment. They are used in laboratories/hospitals to remove any dangerous and maybe potential hazardous stuff from instruments/equipment.

I not sure if this strain is dangerous to humans.
