Greetings
1) What is the composition of Difco sporulation media? I checked Difco and
BD website but couldn't find this product. A google search also yielded no
results. I could find no recipe.
A bit more effort needed on your part on this one as the information is in
the Difco manual. These can be purchased on line.
2) Why does sporulation medium induce sporulation? Are there less nutrients
present?
Its a nutrient defficient medium which becomes rapdily depleted thus
inducing sporulation.
3) Does B. subtilis grow better at 30 C or 37 C?
Depends on the strain and medium used . Why not set up an experiment to
determine optimal growth for the strains you are working with.
Also Judy is correct B.subtilis is Gram positive.
