If you are starting new plants you should start with a good commercial potting soil.
I don't recommend reusing old potting soil.
You can compost the old soil.

It is possible to sterilize old soil but this isn't an easy or a task you may want to do in your oven.

You also can help prevent mold and fungus growth by making sure your plants have adequate air circulation.
