qPCR relative abundance of target bacterial species grown on the oxygen optodes exposed to the HVM shot area and an equivalent area in an unshot control. a Log (10) copy number per biofilm of undisturbed and HVM treated regions of the biofilm. There was a significant reduction in the target species in the treated areas (P ≤ 0.05). Black: Untreated control biofilm, White: HMV treated biofilm. b Log relative reduction in species abundance after HVM treatment. Data were log 10 transformed and presented as geometric mean and 1 SD
