I should have used the word 'enrichment' instead of selective. But
for Riffi's experiment a general media like nutrient agar should be
used as this student sounds like the environment is to be sampled,
remember this is a high school student and looking at the microbes in
the environement would be a better starting point for learning than
getting straight into the pathogenic microbes.
So I think that the media to be used should be nutrient agar. The
question is does this student have access to all of the components?
