33609882-1	2021	This study focused on the nitrous oxide (N2O) generation from the biological nitrogen removal process under different pH levels.	Nitrous Oxide	26-39	phenylalanine hydroxylase	Homo sapiens	118-120	
33609882-1	2021	This study focused on the nitrous oxide (N2O) generation from the biological nitrogen removal process under different pH levels.	Nitrous Oxide	41-44	phenylalanine hydroxylase	Homo sapiens	118-120	
33609882-3	2021	The mean gaseous N2O emission accounted for 0.329%, 0.103%, 0.085%, and 0.793% of the influent total nitrogen at pH of 5, 6, 8, and 9, respectively.	Nitrous Oxide	17-20	phenylalanine hydroxylase	Homo sapiens	113-115	
33609882-6	2021	The impacts of pH on N2O generation were more likely related to the response of bacterial enzymes and nitrogen compounds, rather than the feedback of bacterial community structure itself.	Nitrous Oxide	21-24	phenylalanine hydroxylase	Homo sapiens	15-17	
33609882-7	2021	Above all, an influent pH range of 6-8 is recommended for nitrogen removal and N2O mitigation in anoxic-oxic process.	Nitrous Oxide	79-82	phenylalanine hydroxylase	Homo sapiens	23-25
