There was a useful discussion on Exakta list about fungi and UV.
Apparently, hard UV can stop fungus grow, but Sun's UV rays can even 
hasten the growth of some fungi. Typical UV tubes will do it also..
The best way to remove fungus is undoubtely a fungicide :),
you may also try silica gel in large quantities. 
I sent links to info on excellent Robert Monaghan website in my 
other letter on the same subject :)
