Fraction of survival of E. coli in buffer alone versus buffer and gelatin. Survival is calculated based on the initial survival of E. coli in its corresponding buffer alone. A significant difference in survival between PBS (buffer only) and PBS buffer plus ~ 1 ml of gelatin, and between M9 (buffer only) and M9 buffer plus 1 ml of gelatin (P < 0.005) was seen
