Question

The gelatin medium required inoculation with
3 loopfuls of culture. Why was so much organism
required?
Gelatin is a large protein molecule that
requires a lot of gelatinase in order to
completely break down.
Like a flash mob these organisms only
produce gelatinase when their cell density hits
a certain threshold.
The gelatin in the medium can re-form after
breakdown therefore many cells were needed
to effectively destroy the protein.
The organisms needed to exhaust all other
nutrients before gelatinase would be
produced therefore a large amount of culture
is added to increase the rate of nutrient
breakdown.
