Chromobacterium violaceum might be worth a try.
Use almost any soil as long as not too acid.
Keep moist and then very carefully place some sterilised rice grains on 
the surface. Chr violaceum will go for the high C:N ratio and colour 
infected grains deep purple. Carefully remove them and plate out on a 
starch containing medium.
Failing that go for Bacillus cereus var. mycoides. In virtually all 
soils and unmistakeable in colony form.
