Comparison of the ratio change in the obligate and facultative anaerobes. These charts show the comparison of the ratio change (RC) in the number of live bacteria for A: total bacteria, B: total obligate anaerobes, C–H: each of the obligate anaerobes, I: total facultative anaerobes, and J–N: each of the facultative anaerobes. An RC value of more than 1 indicates that the bacterial group survived and even grew after the blending procedure. The box plot depicts the median and interquartile range and error bars represent the minimum and maximum values of the RC from 16 healthy volunteers. Each box plot compared RCs of anaerobic-prep and aerobic-prep, for samples stabilized immediately after blending (RCAn0 and RCAe0), and also for samples stabilized after maintenance for 1 h under the respective anaerobic or aerobic conditions (RCAn1 and RCAe1). Significant differences are indicated by asterisks (**P < 0.01, ***P < 0.001; Wilcoxon signed-rank sum test)
