This thesis examines the ability of betacyanin, a natural red-violet pigment from red pitahaya (Hylocereus polyrhizus) and red spinach (Amaranthus dubius)in inhibiting the growth of bacteria that cause diseases and bacteria attached to surfaces such as glass, polystyrene, polyvinyl chloride, polyethylene, polypropylene, and silicone rubber. Extraction was optimized to produce a betacyanin fraction and various assays were carried out to identify the best betacyanin formulation against a polymicrobial biofilm.
