The growing of bacteria and fungi can be done in any non selective media, only thing depends from temperature of growling - the biodiversity can be various.
PDA is a classic undifine media for mold fungi, but many bacteria will grow on it. LB, NB, and TSB are classical undefine media for bacteria (for some - too protein-based), but many fungi will gro on them...
