Fig. 4. Effects of sucrose addition on the bacterial network properties of the culture systems.

Fig. 4

a Changes in absolute value of negative cohesion, positive cohesion, and absolute value of negative:positive cohesion ratio of total, core and specific bacterial communities in CK (n = 12), CN10 (n = 18), and CN15 (n = 18) groups. The boxes represent the median and interquartile range, and whiskers range from minimum to maximum values. Different asterisks indicate a significant difference at *p < 0.05, **p < 0.01, ***p < 0.001 and ****p < 0.0001 based on Student’s t test. b Changes in robustness (natural connectivity) of total, core and specific bacterial networks in CK (n = 12), CN10 (n = 18) and CN15 (n = 18) groups. CK: without sucrose addition; CN10: the C/N ratio of about 10:1 obtained by sucrose addition; CN15: the C/N ratio of about 15:1 obtained by sucrose addition.
