3.4.2 FAPROTAX Forecast
In this study, we analyzed the ecological functions of prokaryotic bacteria with FAPROTAX. Based on Figure 6-b, the experimental group of symbiotic bacteria displayed a wide range of ecological functions. These functions included intracellular parasites, nitrogen respiration, nitrate respiration, nitrate reduction, and other unidentified functions. These findings provide insights into the functional versatility and contributions of symbiotic bacteria within the ecosystem. The symbiotic microbial functions exhibited distinct changes throughout the experiment. At the end of the initial MHWs, the HA group showed a marked increase in the relative abundance of intracellular parasite bacteria., On the contrary, after the 5-day recovery, the HB group maintained a significantly high abundance of intracellular parasite bacteria. Following the subsequent MHWs, the HC group demonstrated a notable increase in the relative abundance of nitrogen respiration, nitrate respiration, and nitrate reduction bacteria. Additionally, after a 5-day recovery period, the HD group exhibited an elevated relative abundance of nitrate reduction and Other bacteria.
