	abstract = {Microbial densities, functional genes, and their responses to environment factors have been studied for years, but still a lot remains unknown about their interactions with each other. In this study, the abundances of 7 nitrogen cycling genes in the sediments from Hangzhou Bay were analyzed along with bacterial and archaeal 16S rRNA abundances as the biomarkers of their densities. The amount of organic matter (OM) and total nitrogen (TN) strongly positively correlated with each other and microbial densities, while total phosphate (TP) and ammonia-nitrogen (NH3{\textendash}N) did not. Most studied genes were density suppressed, while\&nbsp;nirS\&nbsp;was density stable, and\&nbsp;nosZ\&nbsp;and\&nbsp;hzo\&nbsp;were density irrelevant. This suggests\&nbsp;eutrophication\&nbsp;could limit\&nbsp;inorganic nitrogen\&nbsp;cycle pathways and the removal of nitrogen in the sediment and emit more greenhouse gases. This study provides a new insight of\&nbsp;microbial community\&nbsp;structures, functions and their interactions in the sediments of eutrophic bays.},
