The existence (a) and size (b) of the bacteriostatic circle around the inks filter paper disk (n = 5). The quantitative results were exhibited as mean ± standard deviation, and one-way analysis of variance was employed to make the statistical analysis. When p < 0.05, it means a significant difference (*); when p < 0.01, it represents a very significant difference (**); when p < 0.001, it indicates a very high significant difference (***)Back to article page
