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	
11257884-14	2001	Headspace analysis showed production of N2O, suggesting the enrichment coupled the biodegradation of PAH to denitrification.	Nitrous Oxide	40-43	phenylalanine hydroxylase	Homo sapiens	101-104	
35445300-12	2022	In contrast, the N2O emissions from the growing season were controlled by soil temperature, water table level, pH, NH4+-N, NO3--N, total nitrogen, total organic carbon, and C/N ratio, which could explain 14.51-45.72% of the temporal variation of N2O emissions.	Nitrous Oxide	17-20	phenylalanine hydroxylase	Homo sapiens	111-113	
33257072-2	2021	Current knowledge gaps include how nitrification-related N2O is associated with soil microbes in different pH soils.	Nitrous Oxide	57-60	phenylalanine hydroxylase	Homo sapiens	107-109	
33257072-9	2021	The results showed that N2O yield for AOA and AOB varied with soil pH.	Nitrous Oxide	24-27	phenylalanine hydroxylase	Homo sapiens	67-69	
33257072-14	2021	To conclude, soil pH was a key factor affecting the contribution of ammonia oxidizers to nitrification-related N2O emissions.	Nitrous Oxide	111-114	phenylalanine hydroxylase	Homo sapiens	18-20	
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
