Sugar inhibition assay. Data represent the effects of d-galactose, α-d-glucose, d-fructose, d-mannoheptose, l-rhamnose, d-cellobiose, lactose, sucrose, and d-raffinose on tailocin adsorption to B. cenocepacia strain PC184. The titer was expressed as the reciprocal of the highest dilution showing inhibition. Asterisks (*) indicate sugars that inhibited tailocin BceTMilo adsorption. Results are representative of triplicate experiments. Each bar represents the standard deviation.
