Summary: | Nitrospira
is the most diverse genus of nitrite-oxidizing bacteria, and its members are widely spread in various natural and engineered ecosystems. In this study, the phylogenetic diversity of
Nitrospira
and monthly changes of its abundance from Zhanjiang Bay were investigated. Phylogenetic analysis showed that among 58 OTUs with high abundance, 74% were not affiliated with any previously described
Nitrospira
species, revealing a previously unrecognized diversity of coastal
Nitrospira
. The abundances of both
Nitrospira
and
Nitrospina
exhibited a significantly monthly change. During most of the months, abundance of
Nitrospina
was greater than that of
Nitrospira
. In particle-attached communities, either abundance of
Nitrospina
or
Nitrospira
was highly correlated with that of ammonia-oxidizing archaea (AOA), whereas abundance of ammonia-oxidizing bacteria was only highly correlated with that of
Nitrospina
. In free-living communities, either abundance of
Nitrospina
or
Nitrospira
was correlated only with that of AOA. These results suggest that both
Nitrospira
and
Nitrospina
can be involved in nitrite oxidation by coupling with AOA, but
Nitrospina
may play a greater role than
Nitrospira
in this tropical bay
