which uses methane as electron donor to reduce nitrite into dinitrogen. It is a promising
clean bioprocess for denitrification in wastewater treatment. However, the low reaction rate
and slow growth rate of N-DAMO bacteria within NC10 phylum limit the application of the
process. In this study, we chose vitamin, heme, nucleobase and betaine to investigate their
short-and long-term effects on N-DAMO bacteria. The concentrations of the growth factors of …
