kitchen sink drain smells like mildew

I have done everything I can think of since the smell started (vinegar and baking soda, bleach...) We replaced our garbage disposal recently and a smell of mildew began within months. The plumber does not know what the cause is. I remember an Ask TOH show about something similar, but don't remeber the cause. Any ideas? :confused:

Iis there a p trap now not holding water? Some times the water can siphon out and sewer gas enters threw the drains.

We got a new disposal and the smell from it was caused by food particles under the rubber insert in the drain. I just stick my hand in, pull out the insert, and wash it off.
You can run pieces of lemon or orange through after that.
