Slime Mold Growth Medium

[David Kerk]

We are trying to grow Dictyostelium discoidium from an axenic ATCC
preparation.  The recommended medium lists "yeast nucleic acid, 1.0gm/L" as
an ingredient.  Can anyone help as to a supplier for this?  Are they talking
about genomic DNA, or raw stuff with DNA and degraded RNA?  Thanks.
