Subject: does the amount of O2, CO2, and N2 have any effect on mold growth?

its for my science fair project. i've been looking in books and on the 
internet, but i havent found anything. i put the elements in short because it 
wouldn't fit, so again they are oxygen, carbon dioxide,and nitrogen. basically 
i have no info on this. i am going to leave the constant variables as follows, 
temperature is going to be room temperature (78 deg.), amount of gas is i dont 
know, and amout of light is going to be none.
