Table 2.

pH levels within the top 1 mm depth of the tri-species model and single-species model before treatments, after bandage application, and for untreated models. All 10 values from 0 μm to 1000 μm were averaged, and the mean was calculated from n = 9 replicates. ANOVA tests were conducted to compare “Before treatment”-values to “After bandages” and “Untreated”-values.
