Yeah, baking soda works well, but you gotta clean the source with some bleach (10 parts water to 1 part bleach). It's about the only thing that will kill it safely and permanently. After the baking soda kills the leftover odor, the problem should be solved.
The OP didn't seem to imply there was any visible mold growth. But just in case, I'd like to clarify the process a bit.
When cleaning, do the cleaning outside. This will reduce the amount of errant spore in the home. If you can't, then you need to isolate the cabinet in plastic while you clean it to reduce the amount of spore spread in your home.
Do not "sponge" the tainted area with bleach/water if the area is dry. Lightly mist the area with a spray bottle, then proceed to clean. Discard the sponge after you're finish. You might want to wear a mold rated mask if the problem is severe enough. You can read more about it on sites like
black mold info.com. I'm not saying you do have black mold, but mold is mold and the process is usually the same for any mold.
It's rarely done with exception to antique preservation work, but there is a product called CPES (used to treat wood rot) that seals wood and supresses new mold growth (the anti-mold growth is not advertised). CPES is a two part epoxy that is
very thin, exactly like water. I've used this on some areas of the house to stabilize dry rot and suppress mold growth. In the manner I've applied it, it's meant to be a temporary fix but I'm aware of some people using it as part of a permanent process. The drawback is CPES gives a real shine to wood, effectively strips any paint (it can be painted over), and it's a little on the expensive side. Other effective methods is treating the wood with a copper solution such a Copper-Green wood preservative (gives the wood a gross green color) and Jasco Clear Copper wood preservative (tints the wood just a tiny bit in its natural color). Both products are fantastic at supressing mold and are fantastically toxic

You'll need to treat the wood with the bleach/water solution before applying the preservatives though.
It probably goes without saying, but don't ever let the wood get wet again.
