Hardening of gelatin does not make any difference as to gelatin's
susceptibility to fungi, bacteria, bugs, etc. Proteolytic enzymes
would dissolve today's maximally rock solid hardened Kodak emulsion to
liquid gel, and this is exactly how people strip off the emulsion from
products to reverse engineer. Bacteria that secrete similar
proteolytic enzymes can break down hardened gelatin and eat them.
