Bacteria trapped in two different types of spearmint gums chewed by human volunteers as function of time.

The number of bacteria trapped in chewed gums for two types of spearmint gums as a function of the chewing time. Error bars denote the standard deviation over a group of five volunteers, with each volunteer having chewed the same gum twice for all time points. A. CFUs trapped per gum piece obtained after molding, sonication and agar-plating. B. Total number of bacteria trapped per gum piece obtained after dissolving the gum and performing qPCR.
