What is the best way to clean mold/mildew from under bathroom floors?

Question:When I moved into my apartment I noticed that under the floor where the tub meets the floor there is a growth of mold that seems to be growing. I was wondering if anyone had any suggestions for cleaning this mold out from under the floor? Realize as well that I cannot do too much "construction" since it is a rented apartment. Thanks for the help.

Answers:
I would use bleach diluted with water on the mildew. I hope it is not under the floor if it is the landlord needs to repair. Especially if you are allergic to mold/mildew. Also I use Oda Ban this is a good product for mildew too and it is good with bad odors it will kill germs too. I use it on stubborn stains in my own home.
