Spatiotemporal distribution and potential functions of N₂O-reducing bacteria in the waters of the Pearl River Estuary.

ABSTRACT:

Background

The reduction of N₂O to N₂, catalyzed by two kinds of N₂O-reducing bacteria, is the only known biological pathway of N₂O sink. However, the distribution and function of N₂O-reducing bacteria in estuarine waters remains unknown. This study investigated the distribution and community characteristics of two clades of N₂O-reducing bacteria (clades I and II) and their potential function in the waters of the Pearl River Estuary (PRE).

Results

Our results reveal that the gene abundance of the NosZ-II type of N₂O-reducing bacteria was remarkably higher than the NosZ-I type, specifically 2.29 to 16.41 times higher in summer and 1.63 to 16.68 times higher in winter, indicating that the NosZ-II type
