Concentration (bacteria/mg) of four genera at each pH range with standard deviation and median. a Lactobacillus spp. show a robust propensity (p = 0.003) for the lowest pH range (4.5–5.0). b Streptococcus spp. have variable concentrations at different pH ranges, and no correlation to any pH group was observed. c Prevotella spp. revealed a strong tendency (p = 0.042) for pH range (5.5–6.0). d Fusobacterium spp. showed no propensity for any pH group. They could be considered outliers with very low concentration levels
