Yes. Despite what some people have said on this forum it is possible to sterilize in the microwave.
Many people use it for kitchen sponges.
The article below from researchers at the university of florida showed that its even possible to sterilize syringes killing even Bacillus cereus spores, its just it takes 12 minutes to do so.

If I am sure that the microwave can and will destroy most bacteria, and that a proper protocol might increase its efficiency I find what you give us is a PR note that do not link to any primary source (not surprising, but annoying, even more so knowing that PR dept are known for often arranging the result to make them more interesting...).
The second thing is that there are norms and protocols to prove that a sterilization protocol is working, and interestingly, they are not used nor mentioned in this. For one thing, the common tests are based on the survival of Bacillus stearathermophilus, not Bacillus cereus. And usually cultures with known numbers of bacteria are used which allow to track the efficiency of the sterilization over time.
So decontamination (reducing the bacterial load to safe level) in a microwave, sure. Sterilizing, not so much.

conditions for sterilization have been established clearly for a long time now

I highly doubt any kind of microwave treatment would effectively kill spores.

An interesting one for the classification of the microwave, we shall determine it by making some aspect that could be use to see the function. It was the function that should be the way to use it for a long period. It was highly recommended to make some action to know the result if they trying to sterilize.
