There has never been a report of any Pseudomonad exhibiting any notable
resistance to heat. Since proteins that lack heat protective characteristics
tend to denature at 55-60 deg. C it might be dificult to calculate a D value
at 70 since death would occur fairly quickly.
Another thing in sterilization that people often forget is just how much more
resistant spore bearing organisms are to heat, alkylation and oxidation than
are vegetative cells. The differences in resistance are really emormous.
