River-bay system is a transitional zone connecting land and ocean and an important natural
source for methane emission. Methanogens play important roles in the global greenhouse …

Methanogenesis from oxic water has been proven to be a significant component of methane
source in large and deep freshwater ecosystems. However, the biogeography of …

Methanogens are an important biogenic source of methane, especially in estuarine waters
across a river-to-sea gradient. However, the diversity and trophic strategy of methanogens in …

Methane is a potent greenhouse gas and produced mainly by methanogens. Few studies
have specifically dealt so far with methanogens in estuarine environments. In this study …

Aquaculture ponds represent ecologically relevant environments to study the community
composition and diversity of methanogenic assemblages, as well as their interactions with …

Methanogen populations of an intertidal mudflat in the Yangtze River estuary of China were
investigated based on the methyl coenzyme M reductase A (mcrA) gene using 454 …

Freshwater reservoirs are an important source of the greenhouse gas methane (CH 4).
However, little is known about the activity and structure of microbial communities involved in …

Studies on methanogenesis from freshwater sediments have so far primarily focused on lake
sediments. To expand our knowledge on the community composition of methanogenic …

Abstract Sediments from Xuanwu Lake have been dredged in the past 3 years to improve
the water quality, but methanogenesis should still exist in the newly settled sediment …

Methane emissions from wetlands contribute to the currently rising levels of methane in the
atmosphere. Nonetheless, the assessments of methane-producing Archaea (methanogens) …
