Metabolic Effects of Sucralose on Environmental Bacteria
Growth curves for environmental isolates. Each isolate was cultured in TSB amended with varying concentrations of sucralose. The open circle indicates the positive control, closed circle is the 27.8 mM group, the closed square is the 55.3 mM group, the open square is the 83.7 mM group, and the closed triangle is the 111.7 mM group. The positive control group consisted of no sucralose added to the TSB in order to ascertain normal growth. This was performed to determine the effect that sucralose had on bacterial growth. The 83.7 mM and 111.7 mM concentrations were significantly () inhibited compared to the control group for each isolate. The 55.3 mM concentration was significantly () inhibited compared to the control group for Stenotrophomonas sp. and Ensifer arboris.
