Wont micro-organisms quickly adapt and start producing UV resistant strains?

The germicidal effect is a function of the DNA being directly affected by the UV rays and breaking apart. Very few organisms exist that could adapt, this would require external shells, skin etc, not typically found in microorganisms.

Tardigrades and organisms ables to survive space by having more efficient DNA repair mechanisms.

Unlikely for most organism, true
