However, if treating ammonium in the CK incubations as indigenous background and deducting it from corresponding NF incubations, the remaining ammonium (net NH 4 + ) in NF incubations showed a decreasing trend along increasing WFPS levels, suggesting a possible active net ammonium consumption under higher moisture conditions ( Table 1 ).
By analyzing the α-diversity at each time point in the three groups, our study showed that in the EODF-SCI group, the gut microbiota structure changed dynamically, the abundance of gut microbiota showed a trend of decreasing and then increasing, and its diversity showed a trend of decreasing, then increasing, then decreasing, and finally increasing.
We also observed that under different carbon-nitrogen ratios (DOC: NO 3 − ), the content of NO 3 − -N in the reaction system showed a downward trend ( Figure 6C ), while the content of NH 4 + -N showed a trend of rapid increase and then gradual decrease ( Figure 6D ), and at the same time, the higher the value of DOC: NO 3 − , the more dramatic the changes in the NO 3 − -N and NH 4 + -N content ( Figures 6C , D ).
