Dear Michael,

I study pombe in a lab where every one else studies cerevisiae.  I tried
growing pombe on our version of SD medium which basically consists of
Difco yeast Nitrogen Base (YNB) + Casamino Acids (+Trp, Ura or Ade if
needed).  It grew much slower than on EMM.  I then found that fission
yeast actually will grow well on YNB with only the supplements needed (in
my case Ade, Ura, His and Leu).  I call this media NBA or Nitrogen Base
Agar after the following reference (Ponticelli, A. S. and Smith, G. R.
(1989) Genetics 123, 45-54) except I use 2% glucose.  I hope this helps.
