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.
